First BMW M4 Coupe Video Footage: Performance Testing at the Ring

We brought you the first photos of the 2015 M4 Coupe prototype earlier today, now have a first live look and listen at the prototype in action on the Nürburgring.

What you're seeing and hearing is the F80 M3 / F82 M4's anticipated inline 6 cylinder engine with multiple turbochargers, pushing approximately 450 horsepower. The engine has been rumored to be an extensively reworked and reinforced N55 6-cylinder engine with a strengthened aluminium block with a heavily modified cylinder head. The Induction technology is said to be completely new as will be the latest bi-vanos variable valve timing. But, we also think there may be a possibility that the engine turns out to be a reworked/enhanced version of a successor engine to the N55 (which has not yet been introduced).

The photos of this prototype posted earlier today shows that this is a DCT transmission equipped M4.

Keep in mind that a prototype's sounds are one of the aspects of the development process and what you hear now may very well undergo further changes.

For comparison sake, we have also posted the latest F80 M3 sedan prototype spy video (also from the Nürburgring). Expect the F80 M3 to be introduced in late 2013 - early 2014 and the M4 to come no earlier than late 2014.
