In its quest to be environmentally friendly, BMW plans to convert all its M cars to turbo power. Purists mutter darkly about the end of an era and the passing of the normally aspirated engine. The next generation of the M3, M5 and M6 will be but pale imitations of the past, they say.
All it takes is one slug of supersonic travel from the 2010 Manhart Racing V8R Biturbo to blow the argument out of the water. This modified M3 from the shops of Gunther Manhart GmbH comes with the whole twin-turbo 4.4-liter drivetrain from the BMW X6 M, pretty much the engine that will power the next M5.
Gunther Manhart tells us that we have 697 horsepower (SAE net) at our disposal.
