AMS Performance’s Alpha 7 E63 4MATIC has more horsepower than most people know what to do with. And it runs 10s!

Mansory, surprisingly, didn’t go all freaky with the M1000, which is based on the new Mercedes-Benz S63 AMG, and left the exterior rather subdued. That’s a good thing because there’s 1,000 horsepower under the hood, making this sedan one of the best sleepers ever.

I’ve never thought that the 577 horsepower pumped out by the E63 AMG S-Model is not enough. Apparently, the guys over at Vath tuning have, and figure the car needs a 28-percent boost.

Kleemann modified the turbos, upgraded the ECU, added a better flowing exhaust system, increased the size of the intercoolers, and did a whole host of other subtle changes. The effect? 850 horsepower and 970 lb-ft of torque. Brilliant!

The owner was testing out a new tune and exhaust system when it seems the straps went loose and the car almost shook itself off the rig.

Brabus is hard at work developing its version of the Smart ForTwo. The hotted-up city car should have more aggressive bodywork, including a bigger grille, a different front bumper and twin exhaust pipes.

Fast sedans wearing the letters AMG are nothing new, but this 10-Second E63 is just redonkulous. Yes, that’s a technical term.
