Brabus rockets the Mercedes S65 to 900 horsepower

Some people you just can't please. They take a look at a vehicle with 621 horsepower and 738 pound-feet of torque on tap – one of the most powerful cars money can buy – and say that's still not enough. Fortunately there are companies like Brabus that cater to just such individuals.

The Mercedes tuner extraordinaire brought the Rocket 900 to the Geneva Motor Show this year. It's based on the S65 AMG – yeah, the one with the twin-turbo V12 – but takes it a step or ten further. For starters, Brabus has bored the engine out to 6.3 liters and hooked up new turbochargers, exhaust, intake and more – cranking output up to 887 hp and a mind-bending 1,106 lb-ft of torque.

Of course it didn't stop there, revising everything from the limited slip differential and air suspension to aero kit and interior. The result? Try 0-62 in 3.7 seconds, a 217-mile-per-hour top speed and a price tag approaching $400,000.
