Pictures of the BMW M3 and M4 have leaked online prior to the cars' official unveiling. The images reveal the final production version of both models, which will make their world debuts at the Detroit Motor Show in January.
An official teaser video was released yesterday but revealed nothing more than the profile of both the M3 and M4 highlighted by neon lights, now we can see the models in final production trim.
We already know the M4 Coupe will replace the two-door version of the of M3, but both will be powered by the same 424bhp 3.0-litre twin-turbo engine.
The new engine is smaller than the 4.0-litre V8 that powered the outgoing BMW M3 but the new twin-turbo motor is more powerful and fuel efficient. Power is up by 10bhp and torque is up to 500Nm – an increase of 100Nm.
Coupled with the 80kg weight reduction, the M3 and M4 should hit 62mph in around 4.5 seconds - but no official performance figures have been released as yet.
The new M models will be launched in the summer and pricing is expected to be announced closer to that date. But you can expect to pay around £57,000 for the M4 and slightly less for the M3.
