BMW's newest M3 sedan was caught testing, and the wide fenders were a dead giveaway for our photographers. Check out the pictures below.
We wish we had more info about powertrains and the like but your guess is as good as ours. In all likelihood, the big, high-revving V8 will take a bow in favor of a turbocharged inline six. We've heard crazy rumors of a tri-turbo I6 in the past, but we'll probably see something like the 1M's I6 make an appearance that is, a massaged version of the N54 twin-turbo I6 used in the 335i, albeit with a lot of power. Lighter weight will also play a part, helping to reduce the need for big power numbers.
