Obviously, these are still early development vehicles, so it's hard to know whether these changes are in any way meaningful. Up front, this M5 still has an air intake stretching all the way across the lower portion of the bumper. The earlier shots showed this piece with a uniform width, but the designers added a little flair this time by lifting the center portion slightly for a more attractive look. Comparing the two examples in profile, the suspension has seemingly been lowered on the latest one to tuck the tires closer to the fender lips. Most parts have carried over, though, including the massive, cross-drilled brake rotors and quad exhaust tips poking out from the rear.
The next M5 should have no problem backing up its mean looks, though. All indications, including earlier spy shots, suggest that the high-performance sedan will gain all-wheel drive, at least as an option, and power will be around 600 horsepower. While about the same as the current 30th anniversary edition, the future 5 Series will reportedly follow the lead of the latest 7 Series by going on a big diet thanks in part from a new, lighter platform.
