The tuners from G-Power have released their upgrade performance pack for the new 2009 BMW Z4 E89. The stock Z4 outputs 306 hp/400 Nm of torque, while the upgraded G-Power 2009 BMW Z4 develops 345 hp/480 Nm of torque. The extra juice of the G-Power 2009 BMW Z4 sDrive 35i comes from the tuner's BI-TRONIK performance module which reduces the car's 0 to 100 km/h time to 4,7 seconds from 5 seconds.
Another highlight of the G-Power 2009 BMW Z4 program are the 20 inch SILVERSTONE DIAMOND alloy wheels that come with MICHELIN Pilot Sport tires, a coil-over suspension and a stainless steel sport rear muffler.
