BMW is definitely preparing a performance version of the 1 Series coupe. It's not certain at the moment whether it will be called the BMW 135is, the BMW M1 or the BMW 1 Series M, but this latest spy video shows the almost completely undisguised vehicle during testing. The clip was shot on the Nurburgring race track and offers the first occasion to listen to the engine of the BMW 135is / M1 / 1 Series M coupe. Most sources believe the BMW 135is / M1 / 1 Series M coupe will be powered by a 322 hp 3.0-liter twin turbocharged six cylinder engine.
