The video shows the new, sleeker style of the upcoming model with a deep front spoiler and aggressively fat twin exhaust outlets. The M5board guys behind the wheel of the tuned, 450kW BMW M3 almost have a hard time keeping up with the new model suggesting that it could be a 650i variant of some sort, possibly equipped with a version of the desirable 4.4-litre, twin-turbo V8.

Notice Chris Bangle's controversial design is non-existent on the first prototype, too, as the boot lid looks more... proportionate, confirming that BMW has changed its design language for future models.
