Brabus Mercedes CLS the "world's fastest sedan"

It seems the Mercedes CLS can be either a coupe or sedan, depending on what seems most appropriate at any given moment. To Mercedes, it's a cool coupe. To German's Brabus, it's a sedan. Why? Because the tuner's CLS-based Brabus Rocket hit a speed of 227 mph (362.4 km/h) this week, making it the fastest "sedan" in the world. The car has a twin-turbo V12 engine from the latest Mercedes 600 models, pushed to an incredible 730 horsepower. The car also offers the fastest acceleration for any "sedan" -- 0 to 62 mph in 4.0 seconds, 0 to 124 mph in 10.5 seconds, and 0 to 186 mph in 29.5 seconds. Power is transferred to the rear wheels via a modified five-speed automatic transmission and the Brabus locking differential. The car has 11-inch-wide tires at the rear plant the power, and massive 12-piston brakes in the front with 15-inch rotors to keep all that power under control. Lastly, the car has has a custom-calibrated height-adjustable coil-over suspension system. Gallery after the jump...
