These renderings come courtesy of Bimmerpost, and the design changes make the new M5 appear more aggressive than the older F10 version. Also, the carbon fiber roof is a nice touch and the M mirrors fit right in with the car's overall sporty styling.

To recap, we can expect to see heavily restyled bumpers, different kidney grille inserts, wider front wings with chromed vent elements, M mirror casings, wider sills, a prominent rear diffuser and of course the M5's signature quad-tailpipes.

The new M5's twin-turbocharged 4.4-liter V8 engine should be good for over 600 HP, and a blistering 0-100 km/h (62 mph) acceleration time of around 3.5 seconds - that is, if you buy into all the rumors. The next-gen M5 is also anticipated to be the first non-SUV from BMW's M brand to be offered with the all-wheel drive as an option.
