With Efficiency to Pure Driving Pleasure.
The new BMW 1 Series Coupe.


The new BMW 1 Series Coupe concentrates on one feature in particular: pure driving pleasure. Indeed, this compact two-door with its muscular design enhances and expands the very successful BMW 1 Series to an even higher level than before.

Featuring high-performance gasoline and diesel engines, offering agile handling and standing out through challenging, dynamic design, this new performance model simply begs the enthusiast to enjoy the sporting moments in everyday traffic. Conceived as a four-seater with its luggage compartment separated from the passenger compartment and with the rear seat backrest offering a 60 : 40 split as standard, the BMW 1 Series Coupe also ensures a high level of all-round function and practical value right from the start.

The focus with this model is however clearly on Sheer Driving Pleasure BMW style. This comes out particularly in the top-of-the-range BMW 135i Coupe offering a truly unique level of performance on the road.

And like its five- and three-door counterparts in the BMW 1 Series, the new two-door model obviously stands out also through its exemplary efficiency.

Apart from the six-cylinder gasoline engine featured in the BMW 135i Coupe, there are two four-cylinder turbodiesels of the latest generation in the BMW 123d Coupe and the BMW 120d Coupe.

Boasting these power units, all three model variants offer top performance versus the competition both on the road and in terms of fuel economy.

Indeed, through its remarkably good balance of performance and economy, the new BMW 1 Series Coupe dramatically proves the success of the BMW EfficientDynamics development strategy combining significant advantages in fuel economy with an equally impressive improvement of dynamic performance through the specific modifications and improvements made within the car itself and in the engine.

Following in the footsteps of the BMW 02 with maximum efficiency and agility.

Introducing the 1 Series, BMW has successfully extended its model range to the lower end of the market, at the same time enriching the compact segment with the first and to this day only rear-wheel-drive model in the market.

Now the BMW 1 Series Coupe bears out the sporting spirit of this model series in terms of agility and handling to an even higher standard, using the benefits of compact dimensions and low weight consistently for further optimization of driving dynamics.

This is not the first time that BMW is setting the standard in driving pleasure in the process of entering a smaller model segment.

On the contrary – the BMW 02 Series launched in 1966 is acknowledged to this day as the forerunner for driving dynamics and agility. Rear-wheel drive, powerful engines and space for four – these were the elementary features of this model series so successful for 12 long years.

Entering the US market: the BMW 1 Series continues its global success.

With the BMW 1 Series Coupe entering the market, the BMW 1 Series is now set to make its debut also in the USA as the entry-level model leading into the BMW range. Indeed, the launch of the BMW 135i Coupe will give the concept of sports driving pleasure in a compact car its ultimate breakthrough also in the US market, the BMW 1 Series thus continuing its worldwide story of success. And at the same time the debut of the BMW 1 Series in the USA is significantly expanding BMW’s presence in the international marketplace.

Exterior design: clear distinctions versus the competition.

The new BMW 1 Series Coupe raises the design language so typical of this model series to a new, even more distinctive level. The sporting proportions of the car give it a unique look in the compact segment, the long front end, the passenger compartment – or the “greenhouse”, as it is sometimes called – moved far to the back, and the short rear end clearly distinguishing this two-door performer from its competitors.

Seen from the side, the shoulder-line of the car beneath the window area is the most striking element, while the widely flared side-sills accentuate the convex/concave surfaces of the side body panels. Interacting with the muscular wheel arches, these powerful contours clearly emphasize the sporting character and performance of the BMW 1 Series Coupe.

In its front end design, the new Coupe stands out clearly as a member of the BMW 1 Series: The design of the radiator grille, the kidney grille so typical of BMW with its powerfully accentuated chrome frame and headlights, is identical on all models.

The new body color Sedona Red metallic is exclusive to the BMW 1 Series Coupe, the range of body colors being rounded off by eight further metallic paintwork colors and three non-metallic options.

A feature typical of a BMW Coupe is the dark, glazed B-pillar creating the impression of one consistent window area extending from front to rear.

Forming a clear contrast to the stable bodyshell of the car, the greenhouse looks light and agile. And the “Hofmeister kick” so typical of all BMWs stands out as a particularly dynamic element.

Yet another feature characteristic of the new Coupe is the typical roof line extending down to the deliberately short and compact rear end in a striking, dynamic angle. The wide, frameless door, finally, as well as the B-pillar raked to a steep angle, shift the visual center of gravity of the car’s silhouette further to the rear.

Horizontal light edges giving the rear end a powerful and dynamic look.

The new BMW 1 Series Coupe boasts a powerful and dynamic rear end including a fully integrated third brake light. As a particularly sporting feature, the luggage compartment lid comes with a spoiler literally chiseled into the rear end of the car, accentuating the short rear section and building up extra downforce on the rear axle at high speeds.

The breakdown of individual sections within the L-shaped rear lights follows the horizontal orientation of the car’s lines at the rear. The back-up lights and direction indicators, for example, form a white band, with additional, horizontal light conductors integrated in the rear light clusters and offering a homogeneous lighting effect with the help of light-emitting diodes (LEDs).

Featuring this design highlight already to be admired on other model series, the BMW 1 Series Coupe stands out clearly as a genuine BMW also in the dark. And the brake lights operating in two stages as a function of brake power are yet another feature typical of BMW, with the additional benefit of extra safety on the road.

Soft radii and horizontal shapes within the car.

The interior of the BMW 1 Series offers clear and at the same time solid, sophisticated flair. Dynamic, horizontal elements create a formal connection between the front and rear, with the cockpit characterized by taut but widely stretching lines and surfaces.

The upper section of the dashboard, in turn, is finished in black, with high quality, natural-looking surface grain further enhancing this touch of quality.

The lower section of the dashboard comes in either black, gray or beige, like the rest of the interior, again emphasizing the orientation of the car through its horizontal design and creating a generous feeling of space.

The control console for entertainment and air conditioning is integrated smoothly and harmoniously into the dashboard through its soft radii and flowing surfaces. The Controller featured in the optional iDrive control system is integrated directly into the center console, again following BMW’s characteristic philosophy. Galvanized pearl gloss surfaces, finally, are to be admired on the door openers, on the glove compartment opener, on the radio’s rotary knobs, on the knobs of the optional automatic air conditioning, on the iDrive Controller, and on the ornamental trim strips featured on the optional leather sports steering wheel.

Four seats and many options for customization.

The BMW 1 Series Coupe comes as standard with two individual seats at the rear offering the car’s occupants a high level of driving comfort. The armrests and the cloth or leatherette inserts integrated in the side panels take up the design of the door linings.

The BMW 1 Series Coupe is available with a choice of no less than four upholstery options harmoniously matching the interior with the body color of the car and emphasizing the individual style of the driver: two cloth, one cloth/leather combination, and one leather upholstery option. Naturally, these upholstery options may be combined in the appropriate colors within the three color worlds and with no less than nine equipment and trim colors.

The trim bars are available with a choice of no less than six versions including aluminum in fine polished look, particularly sophisticated, grained poplar, high-tech titanium, and high-gloss Diamond Black as well as Cashmere Silver.

BMW 135i Coupe in unique look.

To give the car a truly unique look, the BMW 135i Coupe as the top version in the new model range comes as standard with an optimized M aerodynamics package modified versus the M Sports Package. With its extra-large, central air intake, the front air dam highlights the sporting character of the car. The two air intakes at the side in unique design are split horizontally by a center bar and border on slightly contoured flaps additionally accentuating the wide front end of the BMW 135i Coupe. A further sign of distinction is the chrome-plated bars in the kidney grille to be found only on the BMW 135i.

The side-sills on the BMW 135i Coupe are accentuated and contoured even more than on the other models, an additional light edge highlighting the wedge shape of the car. The rear air dam of the BMW 135i Coupe, in turn, incorporates an anthracite-colored insert at the bottom and is wrapped further around the wheels than on the other model variants, emphasizing the wide track of the car. An additional small spoiler lip referred to in motorsport as a “gurney” serves to optimize the car’s aerodynamics. And last but not least, the tailpipes are finished in dark chrome at the rear.

Twin Turbo technology for pure energy in the BMW 135i Coupe.

The top model in the range is the BMW 135i Coupe offering a truly unique standard of performance in the compact class. This outstanding model is powered by a 3.0-litre straight-six featuring Twin Turbo technology and second-generation direct gasoline injection (High Precision Injection).

Maximum output of 225 kW/306 hp and peak torque of 400 Newtonmetres/295 lb-ft offer all the power and performance required to set a new standard in terms of driving dynamics.

Responding immediately to the driver’s commands whenever required, the turbocharged power unit again offers that Sheer Driving Pleasure so typical of BMW: Standing up even against competitors from higher segments of the market through its supreme performance, the two-door BMW 135i Coupe accelerates to 100 km/h in just 5.3 seconds, with top speed limited to 250 km/h (155 mph). Average fuel consumption according to the EU standard, in turn, is just 9.2 litres/100 kilometers, equal to 30.7 mpg imp.

High Precision Injection – second-generation direct gasoline injection – plays a key role in the car’s concept of limiting fuel consumption to a minimum: Compared with an equally powerful turbocharged engine featuring intake manifold injection, the new power unit in the BMW 135i Coupe offers a reduction in fuel consumption by approximately 10 per cent.

BMW 123d Coupe: offering the best in efficiency and performance.

The BMW 123d Coupe opens up a new dimension of EfficientDynamics, making its world debut with a new 2.0-litre four-cylinder diesel featuring Variable Twin Turbo technology and common-rail fuel injection.

Maximum output of this all-aluminum power unit is 150 kW/204 hp, with peak torque of 400 Newton-metres/295 lb-ft at 2,000 rpm and top speed of 238 km/h or 148 mph.

The car’s sporting performance is also borne out by acceleration to 100 km/h in 7.0 seconds. And with average fuel consumption in the EU test cycle of just 5.2 litres/100 kilometers (equal to 54.3 mpg imp), the BMW 123d Coupe ranks right at the top in its performance class versus the competition.

Variable Twin Turbo technology ensures particular efficiency in boosting the power and performance of the engine. Featured so far exclusively in BMW’s six-cylinder diesels, this technological concept combines a small and a large exhaust gas turbocharger with one another. At low engine speeds the small turbocharger cuts in first, providing spontaneous power and performance thanks to its lower inertia. At higher engine speeds the large turbocharger comes in to provide additional boost, this combination ensuring supreme power and pulling force at virtually all revs.

Yet a further point is that the new four-cylinder diesel in the BMW 123d Coupe is the first engine with common-rail direct injection where the piezo-injectors deliver fuel into the combustion chambers with extreme precision at a pressure of 2,000 bar.

Turbocharger with variable turbine geometry in the BMW 120d Coupe.

As the most economical variant of BMW’s new sporting two-door model, the BMW 123d Coupe rounds off the model range at the time of its introduction.

This model is also powered by a new-generation four-cylinder diesel.

Developing maximum output of 130 kW/177 hp and peak torque of 350 Newton-metres/258 lb-ft between 1,750 and 3,000 rpm, and offering average fuel consumption of just 4.8 litres/100 kilometers, equal to 58.8 mpg imp, together with a CO2 emission rating of 128 grams per kilometer, the BMW 120d Coupe again sets the standard for supreme efficiency in its segment of the market. Top speed of the new model, finally, is 228 km/h or 141 mph, with acceleration to 100 km/h coming in 7.6 seconds.

The power unit features an exhaust gas turbocharger which, thanks to its variable turbine geometry, ensures optimum development of power for all load ranges. A further important point is that the engines of both the new BMW 123d Coupe and the new BMW 120d Coupe are far lighter than comparable four-cylinder diesels mainly thanks to the aluminum crankcase with its thermally integrated gray-cast-iron cylinder liners. And representing a new generation of diesel engines, both power units naturally come as standard with a diesel particulates filter fitted close to the engine.

Wide range of improvements serving to reduce fuel consumption.

Pursuing the BMW EfficientDynamics development strategy, the BMW 1 Series Coupe naturally comes as standard with a wide range of features serving to reduce both fuel consumption and emissions while at the same time enhancing the driver’s pleasure at the wheel: All variants of the BMW 1 Series Coupe available in the European market feature Brake Energy Regeneration incorporating intelligent alternator control. Applying this principle in the new BMW 1 Series Coupe, the battery is charged only after reaching its minimum charge level during application of the brakes or in overrun, and is disconnected electrically when accelerating. On the road this means more power for that Sheer Driving Pleasure so typical of BMW and, at the same time, a reduction of both fuel consumption and CO2 emissions.

On manual gearbox models with the new four-cylinder power units BMW’s Auto Start Stop function provides greater efficiency above all in city traffic by automatically switching off the engine whenever it is not required, for example when the car is standing at the traffic lights. Then, to re-start the engine, all the driver has to do is press down the clutch pedal.

The gearshift point indicator likewise helps to optimize fuel economy, the electronic “brain” of the engine calculating the optimum gear required as a function of current driving conditions for maximum fuel economy. An arrow symbol then shown in the instrument cluster together with a number indicating the best gear tells the driver when it is ideal to shift gears.

In conjunction with the new four-cylinder diesel engines, the BMW 1 Series Coupe also features active control and management of the air flaps in the radiator grille: as long as the engine does not require any cool air the flaps remain closed, significantly improving the car’s aerodynamics and reducing fuel consumption accordingly.

In combination with the four-cylinder power units, numerous ancillaries are also operated according to current requirements in order to minimize the consumption of energy. The electric motor for the EPS Electric Power Steering, for example, with its integrated Servotronic function, consumes energy only when steering assistance is actually required. The electric coolant pump, to quote another example, does not operate as a function of engine speed, but is rather temperature-controlled, cutting in only when the pump is really needed. And last but not least, the belt drive on the a/c compressor is fitted with an on-demand clutch, the compressor being automatically disconnected as soon as the driver or passenger switches off the air conditioning.

EfficientDynamics also on the automatic transmission.

As an alternative to the manual gearbox, the BMW 120d Coupe is the first model in the range available as an option with six-speed automatic transmission, with the other models due to follow at a later point in time.

The automatic transmission features new converter technology with an integrated torsion damper reducing the loss of energy and allowing shorter reaction and gearshift times. Benefiting from these features, the BMW 1 Series Coupe offers that sporting driving feeling so typical of a BMW also in its automatic transmission version.

The automatic transmission comes complete with a Steptronic function, with paddles for shifting gears directly from the steering wheel available as a further option.

High-tech suspension with newly developed final drive.

In typical BMW style, the new BMW 1 Series Coupe transmits the power of the engine to the rear wheels and from there on to the road. This design concept and configuration – engine at the front, drive wheels at the rear – guarantees optimum traction, good weight distribution front-to-rear, excellent directional stability, and safe handling. And the separation of drive power and steering, to add a further important point, gives the car extremely agile driving behaviour at all times.

The rear axle of the BMW 1 Series Coupe is a five-arm construction reflecting the requirements of the car’s particularly powerful and high-torque engines.

The front axle on the BMW 1 Series Coupe is also built to a standard quite unique in the compact segment: The double-joint spring-strut tiebar axle with its anti-roll bar is made largely of aluminum, offering an optimum combination of superior stiffness and low weight – which, together with the very stable track control arms and thrust rods, as well as exact wheel guidance, makes an important contribution to the car’s driving dynamics.

As the entry-level model into the range, the BMW 120d Coupe comes with 16-inch light-alloy wheels, while the BMW 123d Coupe is fitted as standard with 17-inch light-alloy wheels. In both cases the wheels come on tires with reduced roll resistance making a further contribution to the car’s fuel economy.

As the top version in the range, the BMW 135i Coupe features 18-inch light alloy wheels highlighting the car’s active performance and dynamism. And as yet a further feature the BMW 135i Coupe comes as standard with M Sports Suspension and a high-performance brake system incorporating six-piston fixed callipers on the front axle and two-piston fixed callipers at the rear.

Perfect handling and precision on the road.

With the exception of the top model in the range, all variants of the BMW 1 Series Coupe are fitted as standard with BMW’s EPS Electric Power Steering complete with Servotronic for speed-related steering power assistance.

ABS anti-lock brakes and ASC Automatic Stability Control preventing the drive wheels from spinning when setting off are naturally also featured as standard. CBC Cornering Brake Control – again standard equipment – stabilizes the car whenever necessary during application of the brakes in a bend.

All of these functions are part of the car’s DSC Dynamic Stability Control, which also includes DTC Dynamic Traction Control allowing more slip on the drive wheels, for example when setting off on loose ground or for particularly fast lateral acceleration.

Electronically controlled differential locking function for even better traction in the BMW 135i Coupe and the BMW 123d Coupe.

To ensure optimum traction with the superior engine output and powerful torque characteristics of these models, both the new BMW 135i Coupe and the new BMW 123d Coupe come with special improvements for enhanced pulling force. The main focus is on promoting a sporting and ambitious style of motoring, for example when accelerating out of a bend or hairpin.

Whenever the driver switches off DSC Dynamic Stability Control and DTC Dynamic Traction Control completely in these two model variants, the electronically controlled differential lock in the DSC-Off mode will continue to ensure optimum traction. In the process the inner drive wheel in a bend threatening to spin is slowed down appropriately by applying the brakes in a tight bend. This promotes the car’s traction and pulling force on the road, without a negative influence on its steering behaviour.

High safety standard exceeding international requirements.

The safety concept of the BMW 1 Series Coupe is based first and foremost on the stable and solid body of the entire model series. High-strength steel, the specific structure of the Coupe’s body and special deformation elements serve to meet all legal standards and requirements in international markets and fulfil the conditions for excellent results in all consumer protection tests the world over.

Optimum safety is also ensured by no less than six airbags, crash-optimized seats, three-point inertia-reel seat belts, and headrests for the driver and passengers in the BMW 1 Series Coupe.

Premium standard also in terms of equipment.

Equipment features so far to be found primarily in upmarket cars highlight the premium character of the BMW 1 Series Coupe also in terms of comfort and safety. Available as an option, bi-xenon headlights and Adaptive Headlights complete with integrated Bending Lights make driving in the dark safer than ever before.

The combination of these comfort and safety functions in this car segment is absolutely unique and unprecedented. A further point is that the optional iDrive control system allows the driver via the central Controller – and if he wishes also by voice input – to intuitively control all secondary and comfort functions of the communication system, air conditioning, entertainment, and the optional navigation system.

The audio systems available in the new BMW 1 Series Coupe are among the most sophisticated and advanced in the entire segment. Indeed, individual choice also in the world of entertainment allows optional use of a USB port supplementing the standard AUX connection, enabling the driver or passenger to integrate an external MP3 player such as an Apple iPod into the audio system. A further possibility is to connect a conventional USB stick in order to play music files on the audio system in the car, again in the interest of freedom of choice in every respect.

The steering column adjustable manually for height and reach, height adjustable seats for the driver and front passenger, as well as electric window lifts naturally come as standard in the BMW 1 Series Coupe. And as a feature rarely to be found in a coupe, the rear-set backrest folds down in a highly practical 40 : 60 split to provide a further increase in luggage space over and above the 370 liters already offered by the regular luggage compartment.

An optional 12-volt plug in the luggage compartment, finally, allows convenient operation of external appliances such as a cooling box.

Even more dynamic performance and striking looks provided by the M Sports Package.

The particularly sports-minded driver of the BMW 1 Series Coupe is able to upgrade his car to an even higher standard in terms of both looks and driving dynamics, using the most appropriate components provided for this purpose by BMW M GmbH. The optional M Sports Package therefore offers all the features desired and is already partly included in modified form in the BMW 135i Coupe as standard.

Concept:
More Sport in the Compact Class.

- Consistent expansion of the BMW 1 Series.
- BMW 1 Series Coupe: the new yardstick for top sporting performance in the segment.
- Efficient and agile on the tracks of the BMW 02.


Firmly established in the market, but still quite unique – this is the best way to describe the position of the BMW 1 Series in the compact car segment.

Introducing this outstanding model series, BMW has successfully extended its line-up down to the lower end of the market, at the same time genuinely enriching the compact segment through the first and to this day only rear-wheel-drive model in this part of the market.

The most sporting version of the BMW 1 Series is also BMW’s most compact coupe – a unique combination which gives the BMW 1 Series Coupe its particular appeal and very special style. So now the highly attractive design and the appealing character of a typical BMW Coupe is entering the BMW 1 Series segment, with consistent use of the car’s compact dimensions and low weight in the interest of optimum driving dynamics.

The exceptional torsional stiffness of the body structure, the technically most advanced and sophisticated chassis and suspension in the segment, and perfectly balanced 50 : 50 weight distribution likewise create ideal conditions for nimble and precise handling, interacting with the high-performance six- and four-cylinder power units to provide a truly unique driving experience.

Best results versus the competition – in terms of both performance and economy.

The BMW 1 Series Coupe thrills both the driver and the beholder from the start through its incomparably active and dynamic character standing out clearly over the competition through its unparalleled performance.

At the same time the car offers everything required to combine supreme driving dynamics with impressive efficiency, all engine variants of the BMW 1 Series Coupe ranking right at the top over the competition in terms of their balance of performance and fuel economy. Clearly, this makes BMW’s new two-door sports model a particularly attractive ambassador of the BMW EfficientDynamics development strategy.

Concentrating on pure driving pleasure, the BMW 1 Series Coupe furthermore lives out BMW’s traditional spirit of sporting performance in a particularly modern form. Quite simply, this is the supreme symbiosis of agility and lightness, on the one hand, with superior drivetrain technology, on the other – which has always been the recipe for success in BMW’s most sporting models.

Driving pleasure in compact dimensions: the BMW 02 Series was the forerunner.

This is not the first time that BMW is setting the standard for driving pleasure by entering a smaller vehicle segment. On the contrary – the BMW 02 Series introduced way back in 1966 is acknowledged to this day as the forerunner in dynamic performance and agility. Rear-wheel drive, powerful engines and space for four – for 12 long years these were the elementary fortes of this successful model series.

In its design the BMW 02 Series was characterized by dynamic proportions with a short body overhang at the front, a powerful shoulder-line, a long engine compartment lid, and long wheelbase – styling elements now re-interpreted in the BMW 1 Series Coupe to provide an equally unique look.

Another exciting comparison is that the special edition BMW 2002 turbo ranking even higher than the top model in the BMW 02 Series – the BMW 2002 – marked the absolute climax of thrilling performance even back then. And today the BMW 135i Coupe with its 225 kW/306 hp Twin Turbo power unit offers a modern, contemporary rendition of this car concept in an entirely new class of its own.

Entering the US market: the BMW 1 Series is continuing its global story of success.

Launching the BMW 1 Series Coupe, BMW is now also set to introduce the 1 Series as the brand’s entry-level model in the USA: Introduction of the BMW 135i Coupe in the US market will indeed boost the concept of particularly sporting driving pleasure in a compact car to an unprecedented level in the USA, enabling the BMW 1 Series to continue its worldwide story of success and significantly expand its international presence in the market.

Design:
Powerful, Striking, Unmistakable.

- Design reflecting both dynamic performance and Sheer Driving Pleasure.
- Unique coupe concept rendering the design language of the BMW 1 Series.
- BMW 135i Coupe featuring the M Aerodynamics Package as standard.


Just one look at the dynamic proportions of this unique two-door proves that driving pleasure is the philosophy and creed of the new BMW 1 Series: The long front end, the passenger cell – sometimes also referred to as the “greenhouse” – moved far to the rear, and the short rear end give the car a unique interpretation of the coupe concept making it stand out clearly from the competition.

Through its sporting and powerful overall look, the BMW 1 Series Coupe offers a supreme standard of individual style and emotional strength. Reflecting BMW’s design philosophy, the features of the car are highlighted authentically by the language of exterior and interior design, the dynamically designed surfaces, muscular wheel arches, and long, frameless doors bearing visible reference to the philosophy of rear-wheel drive quite unique in this segment – and, accordingly, to a driving experience otherwise only available in higher classes further up in the market. The generous and stylishly refined interior, finally, likewise reflects the premium character of the car.

Through its challengingly dynamic design, the new Coupe clearly extends and enriches the design language of the BMW 1 Series. Through its looks alone, this two-door brings out all the sporting and agile character of this particular model series in an unusually exciting form.

Above all the BMW 135i Coupe reveals its dynamic character at very first sight, this top model in the range boasting truly unique looks: Visible at very first sight, the modified M Aerodynamics Package featured as standard and carried over from the M Sports Package highlights the BMW 135i Coupe as the most powerful model in this series.

Appealing contrasts: the airy greenhouse resting on a stable body.

Through its sporting proportions alone, the BMW 1 Series Coupe holds an absolutely unique position within the compact segment. The entire silhouette of the car is dominated by striking and powerful lines. The most outstanding feature seen from the side is the distinctive shoulder line beneath the windows extending from the front end of the car along the entire side all the way to the rear lid and subdividing the body of the car into the light roof structure and a compact foundation. At the rear, finally, the shoulder line tapers out into the rear lid just above the rear light clusters.

Powerfully flared wheel arches accentuate the convex-concave surfaces of the side panels, at the same time creating a sleek flow towards the rear of the car, which further reinforces the interplay of light and shade between the side-sills and the lower segment of the side panel, thus serving to stretch out the silhouette even further.

Together with the widely flared wheel arches, the convex-concave surfaces underline the muscular flair of the BMW 1 Series Coupe with all the character of a well-trained athlete. Clearly, this again highlights the car’s permanent urge for performance wherever the driver wishes to go.

Through its innovative, dynamic surface design, the BMW 1 Series Coupe reveals its close relationship to the BMW Z4 likewise standing in its design for agility, progressiveness, and individual style.

The sporting, extra-low greenhouse moved far to the rear appears particularly light and agile in comparison with the muscular body of the car. Its soft contours reflect the underlying concept of such a compact car, clearly distinguishing this Coupe from other fixed-head two-door BMW brand models.

And last but not least, this high quality, sophisticated surface design gives the compact BMW 1 Series Coupe all the character and class of higher model series.

Model-specific and new features at the front of the car.

The outgoing and active expression of the front end clearly reveals at first sight that the new Coupe is a member of the BMW 1 Series. The design of the radiator grille, the typical BMW kidney grille with its powerfully contoured chrome frame, and the headlights reflect the same body features at the front of the five- and three-door models.

Dark-colored trim bars surrounding the lights create a clear optical contrast to the metal surrounds on the striking dual headlights. The optionally available bi-xenon round headlights, together with their corona-shaped light conductor rings serving to provide a daytime light function, likewise characterize the Coupe unmistakably as a BMW. The prominent chrome frame around the kidney grille, finally, adds to the particular style and flair of this compact model.

The new BMW 1 Series Coupe stands out from the three- and five-door hatchback models also through the new design of the air dam. On the BMW 123d Coupe and BMW 120d Coupe, the front air dam features a large central air intake at the bottom and two openings at the side. These openings are split horizontally and border on trim bars reflecting the swept arrow look of the engine compartment.

The fog lamps are integrated in the upper section of the segments formed in this way, a large, homogenous surface without bumper bars characterizing the bumpers positioned beneath.

Authentic in its expression.

The BMW 1 Series Coupe expresses its agile and dynamic character clearly, full of conviction and, at the same time, with absolute passion. The exterior look of the car is straightforward and quite simply smacks of power – self-confident without exaggerated gimmicks.

The BMW 1 Series Coupe clearly stands out as a genuine BMW in every respect, with all the qualities of BMW’s higher model series in terms of premium standards and the quest for leadership in its segment.

A feature typical of a BMW Coupe is the dark, glazed B-pillars creating the impression of a band of windows extending all through the car and further highlighted by the optional Chrome Line exterior. As a particularly dynamic element, the “Hofmeister kick” typical of BMW at the bottom of the C-pillar boasts that characteristic counter-swing to the front. The roof line, in turn, reaches its highest point behind the B-pillar, creating the impression of a genuine wedge shape symbolizing the dynamic performance and sporting character of this agile Coupe right from the start even with the car at a standstill.

The long, frameless door and the B-pillar raked to a steep angle move the optical counterpoint of the car’s silhouette to the rear, creating the impression that the driver’s seating position has also been shifted further back.

Both of these effects again stand for agility and dynamic performance, while at the same time emphasizing the concept of rear-wheel drive in the BMW 1 Series Coupe quite unique in this segment.

Rear-end design also standing out from the rest of the crowd.

The rear end of the BMW 1 Series Coupe is equally powerful and striking in its look, distinctive horizontal lines accentuating the sheer width of the car.

In combination with the widely flared wheel arches, these powerful lines also bear testimony to the safe roadholding of the new Coupe.

As a particularly sporting feature, the rear lid boasts a carefully sculptured contour flap visualizing the short rear end and enhancing downforce on the rear axle at high speeds. And last but not least, the rear end also comes with a third brake light integrated in the rear spoiler.

The subdivision of individual light units within the L-shaped rear light clusters follows the horizontal orientation of lines at the rear, with the back-up light and direction indicators standing out clearly as a white band.

Horizontal light conductors are also integrated into the rear-light clusters, illuminated by light-emitting diodes (LEDs) for a particularly homogeneous lighting effect. Indeed, this design feature already well-known from other model series clearly reveals in the dark that the BMW 1 Series Coupe is a genuine BMW in every respect. And finally, the two-stage brake lights varying in brightness and size as a function of brake power are another feature typical of BMW serving in addition to enhance safety on the road.

The new Sedona Red metallic body color is reserved exclusively for the BMW 1 Series Coupe, which is furthermore available with eight more metallic paintwork colors and three standard color options.

BMW 135i Coupe with distinctive differences in its looks.

As the top model in the range, the BMW 135i Coupe stands out clearly through its modified M Aerodynamics Package. Indeed, right from the start the front air dam with its extra-large central air intake emphasizes the concept designed for superior driving dynamics. The two separate air intakes at the sides, in turn, are subdivided by a dark crossbar and border on slightly flared flaps extending deeper down than the central air intake to guide the air past the front wheels and emphasize the wide front end of the BMW 135i Coupe also in visual terms.

The side-sills of the BMW 135i Coupe also boast their own, distinctive design, an additional light edge reinforcing the wedge shape. Again, this design feature typical of a BMW Coupe creates the impression of dynamic performance right from the start, even with the car at a standstill.

To highlight the BMW 135i Coupe as the top model also from the rear, the middle section of the rear air dam is finished in matt anthracite beneath the bumper, where the integrated diffuser optimizes the car’s aerodynamics.

The side sections finished in body color point towards the rear wheels, accentuating the wide track of the car. A further feature is the dark chrome finish of the tailpipe covers on the exhaust system, while the discreet spoiler lip commonly referred to in motorsport as a “gurney” on the rear lid provides yet a further sign of distinction with a positive impact on the flow of air.

Soft radii and horizontal shapes determine the interior design.

The interior of the BMW 1 Series excels by its clear and at the same timesolid, sophisticated flair. Dynamic, horizontal elements create a formal connection between the front and rear, with the interior offering space for up to four occupants giving the car a standard of class and sophistication otherwise to be admired only in higher segments of the market.

The cockpit is characterized by taut but widely stretching lines and surfaces, with the upper section of the dashboard finished in black. High-quality, natural-looking grain enhances this touch of quality.

The lower section of the dashboard comes in either Black, Grey or Beige, one of BMW’s so-called world colors, emphasizing the orientation of the car through its horizontal design and creating a generous feeling of space.

The control console for entertainment is integrated smoothly and harmoniously into the dashboard through its soft radii and flowing surfaces. It extends into the center console between the two front seats accommodating the Controller masterminding the optional iDrive control system as well as a cup holder. Galvanized pearl gloss surfaces, for example on the opening levers for the doors and glove compartment, on the radio control buttons, on the controls of the optional automatic air conditioning, on the iDrive Controller and on the ornamental trim strips highlighting the optional leather sports steering wheel ensure further optical flair and individual style.

A special design feature integrated on the inside panels of the front doors between the upper waistline and the armrest follows the contours of the surrounding lines and is finished in the same material as the seats. In models finished in Boston leather available as an option, the high standard of quality and sophisticated look is further emphasized by an ornamental seam, while a map pocket is integrated in the lower part of the door lining as a particularly practical feature.

Formal harmony of front and rear.

The BMW 1 Series Coupe comes as standard with two single seats at the rear ensuring a high level of motoring comfort. The armrests as well as the cloth or leather inserts integrated in the side lining take up the design of the front door linings, a storage box between the two seats offering additional space for ods and ends. The rear-seat backrest, finally, is split 60 : 40 for an even higher standard of functional quality in this compact sports model.

To match the color and look of the interior to the respective body color and, at the same time, to emphasize the driver’s individual style, the BMW 1 Series Coupe is available with no less than four upholstery options – two in cloth, one combination of leather and cloth, and one all-leather option. These, in turn, come with a choice of three so-called world colors and nine individual colors.

The interior trim is available in five different versions including aluminum in fine-polish look, particularly sophisticated walnut, titanium with its technical and almost cool touch, as well as high-gloss Diamond Black.

Drivetrain:
Top Performer in Power and Efficiency.

- Prize-winning straight-six in the BMW 135i Coupe.
- Four-cylinder diesel with demanding turbocharger technology.
- Consistent implementation of BMW EfficientDynamics.


Featuring an engine range from 130 kW/177 hp all the way to 225 kW/306 hp, the BMW 1 Series Coupe sets new standards in its segment. All of the power units in the series – both the six-cylinder gasoline engine and the two four-cylinders turbodiesels – offer a particularly impressive combination of dynamic performance, motoring efficiency and running refinement, with superior output on a further improvement of fuel economy and reduced exhaust emissions.

The drive units available for the BMW 1 Series Coupe represent the latest state-of-the-art in BMW engine development and come with all the technologies introduced as part of BMW’s EfficientDynamics development strategy for the purpose of minimizing fuel consumption and exhaust emissions.

The innovations now also featured as standard on the BMW 1 Series Coupe and combined with one another appropriately for each model include Brake Energy Regeneration, Auto Start Stop, a gearshift point indicator, on-demand management of ancillary units, and active improvements in aerodynamics.

These cutting-edge technologies serve to further enhance the already outstanding potential of the newly developed engines in terms of both economy and emission management. So when it comes to acceleration, fuel consumption and CO2 emissions, all variants of the BMW 1 Series Coupe rank right at the top in their respective performance and market segments.

Twin Turbo and High Precision Injection in the BMW 135i Coupe.

225 kW/306 hp from 2,979 cc – figures of this kind clearly characterize the BMW 135i Coupe as the top model in the series. Indeed, the world’s first straight-six power unit with Twin Turbo technology, second-generation direct gasoline injection (High Precision Injection) and an all-aluminum crankcase is the most powerful six-cylinder within the BMW range.

Proudly featured in the BMW 1 Series Coupe, this power unit, already the winner in two categories and in the overall rating of the international Engine of the Year Award, offers a standard of driving pleasure never seen before in the compact car segment.

The BMW 135i Coupe accelerates to 100 km/h in 5.3 seconds and has a top speed limited electronically to 250 km/h or 155 mph. Maximum torque of 400 Newton-metres/295 lb-ft comes within the very broad speed range from 1,300–5,000 rpm, clearly confirming the supreme torque and pulling force of the 3.0-litre. Moderate average fuel consumption in this performance category of just 9.2 litres/100 kilometers (equal to 30.7 mpg imp) in the EU test cycle likewise confirms the qualities of this engine as a particularly fascinating example of BMW EfficientDynamics.

This fascinating power and performance is guaranteed above all by Twin Turbo technology, the combination of two turbochargers each pumping compressed air to three cylinders at a time and thus providing a standard of spontaneity quite unique for a turbocharged power unit. The main advantage of the relatively small turbines is their low inertia when accelerating, eliminating the “turbo gap” so typical of conventional turbocharged power units, that is the “waiting period” which usually elapses until the turbocharger develops its boost and extra power.

Benefiting from this technology, the turbocharged power unit in the BMW 135i Coupe develops the same kind of torque and muscle as a far larger normal-aspiration power unit, while avoiding the inevitable increase in weight of such a larger engine with its adverse effects on the balance of the car.

The introduction of Twin Turbo technology, in combination with High Precision Injection, is therefore a particularly efficient method to offer an even higher standard of power and torque without increasing the weight of the engine.

High Precision Injection plays a key role in reducing the amount of fuel consumed. This second generation of direct gasoline injection enables the Twin Turbo power unit of the new BMW 135i Coupe to provide its extra power without a significant increase in fuel consumption and, at the same time, without making any concessions in terms of driving dynamics.

Positioned within the cylinder head directly next to the spark plugs, the injectors allow unparalleled precision in dosing the amount of fuel injected.

Compared with an equally powerful turbocharged engine using conventional gasoline injection into the intake manifold, the power unit featured in the new BMW 135i Coupe thus offers a significant advantage in fuel economy. And adding the effect of further technologies for greater efficiency such as Brake Energy Regeneration, this creates a balance of driving dynamics and economy quite unique not only in this segment of the market.

Turbodiesel power units featuring a particulates filter as standard.

The turbodiesel power units in the new BMW 1 Series Coupe also enter new dimensions in terms of performance and fuel economy. The first point is that the engines in the BMW 123d Coupe and the BMW 120d Coupe are significantly lighter than comparable four-cylinder diesels. Most of this reduction in weight comes from the aluminum crankcase with its thermally joined gray-cast-iron cylinder liners.

This optimization of engine weight and design ensured from the start in the development process has a positive impact not only on the car’s economy, since the reduction of engine weight also enhances the car’s harmonious distribution of axle load in the interest of even better agility.

Yet a further point is that both diesel engines come as standard with a wide range of BMW EfficientDynamics improvements including Brake Energy Regeneration, the Auto Start Stop function and a gearshift point indicator (on the manual transmission models), active aerodynamics and on-demand management of the engine’s ancillary units. And as representatives of a new generation of diesel engines, the power units featured in the BMW 123d Coupe and the BMW 120d Coupe naturally come as standard with a particulates filter close to the engine.

BMW 123d Coupe setting a new benchmark in output per liter.

The four-cylinder power unit featured in the BMW 123d Coupe, the first diesel in this segment with Variable Twin Turbo technology, develops maximum output of 150 kW/204 hp at 4,400 rpm from engine displacement of 1,995 cc. This makes it the first all-aluminum diesel engine in the world with more than 100 hp output per liter. Peak torque of 400 Newton meters/ 295 lb-ft, in turn, comes at just 2,000 rpm.

Variable Twin Turbo technology offers particular efficiency in boosting the power of the engine. Referred to also as multi-stage turbocharging, this system is made up of a small and a large exhaust gas turbocharger working together in supplying intake air to the four cylinders. Benefiting from its low inertia, the small turbocharger ensures superior torque and pulling force from low engine speeds just above the idling level. At higher engine speeds the larger turbine cuts in to provide extra power and torque, the big advantage of this interplay of two turbochargers being the complete avoidance of the usual “turbo gap”.

The 2.0-litre power unit featured in the BMW 123d Coupe comes with common-rail direct fuel injection incorporating piezo-injectors operating at a pressure of 2,000 bar. With fuel being injected into each cylinder through three openings in up to three portions, the flame spreads smoothly and gently through the fuel/air mixture during the operating stroke, benefiting above all the running smoothness of the diesel engine.

Offering a top speed of 238 km/h (148 mph) and accelerating to 100 km/h in 7.0 seconds, the new BMW 123d Coupe guarantees remarkable performance on the road. And in combination with average fuel consumption in the EU test cycle of just 5.2 litres/100 kilometers (equal to 54.3 mpg imp), this kind of performance clearly proves the consistent implementation of the BMW EfficientDynamics development strategy.

With CO2 emissions of just 138 grams per kilometer, the new BMW 123d Coupe ranks right at the top also in this respect. Indeed, it is the first car with more than 200 hp to offer a CO2 emission rating of less than, 140 grams per kilometer.

High power and low CO2 emissions on the BMW 120d Coupe.

The power unit of the new BMW 120d Coupe also features a very sophisticated turbocharger system in technical terms: The 2.0-litre four-cylinder comes with one single exhaust gas turbocharger fitted with adjustable turbine blades to ensure optimum development of power throughout the entire load range. An electric actuator motor serves in this case to adjust the turbine blades to current load requirements within fractions of a second, ensuring both a spontaneous and direct response at low engine speeds and high output under full load. Maximum turbocharger pressure is 2.55 bar, with diesel fuel being delivered into the combustion chambers by piezo-injectors at a pressure of 1,800 bar.

Displacing 1,995 cubic centimeters, the four-cylinder develops a muscular 130 kW/177 hp maximum output at 4,000 rpm, with peak torque of 350 Newton-metres/258 lb-ft maintained consistently between 1,750 and 3,000 rpm.

This kind of power gives the new BMW 120d Coupe a top speed of 226 km/h (140 mph), with acceleration to 100 km/h in 7.6 seconds. Fuel consumption of just 4.9 litres/100 kilometers (equal to 57.6 mpg imp) and CO2 emissions of 130 grams per kilometer are both exceptionally low.

The new generation of four-cylinder diesel engines is also characterized by a unique standard of smoothness and running refinement. As a result, the less experienced driver or the driver not that well acquainted with the car – for example in the case of a rental car – will hardly feel the difference any more versus a petrol-engined model.

Precisely this is why the new BMW 123d Coupe and the new BMW 120d Coupe come with false filling protection requiring the driver to use a diesel filling pump at the filling station, since a petrol pump would not fit due to the entry lock only a standardized diesel filling pump is able to open.

Intelligent energy management with Brake Energy Regeneration.

The power units of the new BMW 1 Series Coupe offer a particularly impressive combination of dynamics, efficiency and running refinement.

All four engines provide superior power on even less fuel and exhaust emissions reduced to an even lower level than before.

This is achieved, first, by modifications within the engine itself serving to reduce friction forces, through the re-design of the combustion chambers, optimization of the fuel/air mixing process using common-rail fuel injection on the turbodiesels, High Precision Injection on the gasoline model, as well as precise management of both fuel combustion and the supply of air.

The second major area of improvements involves the vehicle itself, again helping to reduce fuel consumption by a significant margin: As an example, all variants of the BMW 1 Series Coupe come with Brake Energy Regeneration using intelligent generator control. In this case electric power for the car’s on board network is generated only in overrun and when the driver applies the brakes. When accelerating, on the other hand, the generator is generally disconnected in order to provide extra drive power.

This concept of intelligent energy management is comparable to the operation of power stations with storage technology, where low-cost energy is stored during the night in reservoirs at higher elevations and then regained during the day in order to meet peak requirements.

Applying this concept to Brake Energy Regeneration in the new BMW 1 Series Coupe, the system is able to determine which driving phases are appropriate for generating electric power then stored in the battery and subsequently fed into the on-board network when required.

To maximize the service life of the battery and provide compensation for the greater flow of energy, the intelligent energy management system, interacting with new AGM battery technology, uses so-called regeneration cycles. In this case the battery is charged with higher voltage pulses from time to time after a certain cycle of charging and discharging, thus ensuring appropriate phases of regeneration.

Auto Start Stop for shorter idling periods.

On the manual gearbox versions of the BMW 1 Series Coupe with a four cylinder power unit, Auto Start Stop serves to enhance efficiency above all in city traffic: As soon as the driver shifts to idle and takes his foot off the clutch, the electronic engine control unit will automatically switch off the engine, reducing fuel consumption at red traffic lights, for example, to zero. Then, to start the engine again, all the driver has to do is press the clutch pedal, with the engine coming back on immediately without any further intervention.

Gearshift point indicator for low-consumption motoring.

Electronic engine control in the new BMW 1 Series Coupe offers substantial assistance in the effective use of fuel also while driving: A gearshift point indicator – that is an arrow symbol coming on in the instrument cluster and specifying the optimum driving gear – shows the driver the ideal point for shifting gears in the interest of maximum fuel economy.

Further reduction in fuel consumption through on-demand management of ancillary units.

Further improvements serving to save fuel likewise do not require any intervention by the driver: The BMW 1 Series Coupe featuring one of the new four-cylinder diesel engines, for example, comes with active control of the air flaps in the radiator grille. So whenever the engine needs less cooling the flaps are closed for a measurable improvement of aerodynamics and, as a result, a further reduction of fuel consumption.

A further point is that numerous ancillary units on the four-cylinder engines are operated only on-demand, again in the interest of minimum energy consumption.

As an example, energy is used for the EPS Electric Power Steering with its integrated Servotronic function only when steering assistance is really required or desired by the driver. When driving in a straight line or at a constant angle in bends, the servo unit does not take up any energy. Another example is the electric coolant pump operating as a function of engine speed and temperature only when really required. Consuming just 200 W as a result of this technology, the electric coolant pump requires only about one tenth of the drive energy consumed by a conventional pump.

Last but certainly not least, the belt drive on the climate compressor is disengaged whenever appropriate by a clutch, with the compressor automatically being disconnected when the air conditioning is switched off. This reduces the drag forces exerted by the compressor to a minimum and gives the engine an even higher degree of efficiency.

100 per cent sports feeling also with automatic transmission.

As an alternative to the six-speed manual gearbox, optional automatic transmission is available to begin with on the BMW 120d Coupe and will later be featured on the other engine variants, too. And like the manual gearbox, this automatic transmission comes with six gears, using an innovative converter complete with an integrated torsion damper.

This reduces energy losses and shortens the reaction and gearshift times on the transmission, the direct connection of engine and transmission serving to enhance the dynamic character of the car and ensure a precise gearshift.

The driver may even shift down quickly by skipping one or several gears, simply by kicking down the gas pedal for particularly fast and dynamic acceleration.

The automatic transmission comes complete with a Steptronic function providing not only the usual automatic mode, but also a manual gearshift either from the gear selector lever or by optional shift paddles on the steering wheel – so that the new BMW 1 Series Coupe offers that sports feeling so typical of BMW also with automatic transmission.

Chassis and Driver Assistance Systems:
Dynamics, Comfort and Safety
Tailored to the Driver.

- Rear-wheel drive setting the stage for sporting behaviour.
- Model-specific drive stability control featured as standard, Active Steering as an option.
- BMW 135i Coupe with M sports suspension.


The BMW 1 Series Coupe offers the driving pleasure so typical of the brand now also in the segment of compact four-door models, the elaborately engineered chassis underlining the dynamic and sporting character of this new BMW. The result is superior steering and driving precision even under extreme conditions reaching the very limits of driving physics.

With its design principle quite unique in this category – engine at the front, drive wheels at the rear – the new BMW 1 Series Coupe offers optimum traction, exemplary weight distribution with approximately 50 per cent of the car’s overall weight on the front and rear axles, respectively, outstanding directional stability and safe handling. And the separation of drive power, on the one hand, from the car’s steering, on the other, is of course the prerequisite for supreme agility on the road.
