Best Mobile Buyer Guide Review Car : 2010 Manhart Racing M3 V8R Biturbo Twin-turbocharged 4.4-liter V8
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.
The Future Is Turbocharged
The 2010 Manhart Racing M3 V8R Biturbo is a glimpse into the future of turbocharged M cars and the performance that tuners will be able to achieve with a simple remap of the engine electronics. After all, that’s what we have here with the V8R Biturbo  an ECU remap and an exhaust system, plus sufficient cooling to keep the whole business from melting. It’s not so far removed from the 570-hp version of this engine that will power the forthcoming BMW M5.
The straight-line performance of this thing is just ridiculous. It’s not just the top speed of over 200 mph, either. This engine is insane from the moment we touch the throttle pedal. There’s a guttural roar from the exhaust and the car just bolts forward. The V8R Biturbo actually involves a full powertrain transplant from the X6 M, so the engine is matched to a six-speed automatic transmission. This might sound slightly wussy, but it’s not. With the automatic, the Manhart Racing M3 is scary easy to drive fast. There’s a roar and then the car just takes off to the sound of screeching rubber. Maybe you can feel a bit of a kick at 3,500 rpm as the turbos spool up, but mostly the car just leaves the vicinity, evidence of BMW’s effort to minimize turbo lag with its twin-turbo system, plus a unique X6 M exhaust manifold that muffles the roar of forced induction.
You soon get used to the seductive interplay of turbos spinning and wastegates flushing as each gear ratio engages, and the yowl of the former M5′s normally aspirated V10 seems very old-school in comparison. That’s the price of progress.
