The M37 is powered by a 3.7-litre V6 engine with 316bhp (very similar to the engine in the Nissan 370Z sports car) and it will do 155mph and 0-62mph in 6.2sec.
The M37 will be followed by a M30d model in October, which is powered by a 3.0-litre diesel engine and by the hybrid M35h in spring next year. Prices start at $53,763.
