The 900 Rocket is the world's fastest four-seater convertible.

German tuner Brabus is taking the Mercedes-AMG S65 Cabriolet to the next level at the Frankfurt Auto Show. The brand will introduce a model named Rocket 900 that's billed as the fastest and most powerful four-seater convertible in the world.

Brabus started with the S65's 6.0-liter twin-turbocharged V12 engine. Its engineers made a long list of modifications including bumping the displacement up to 6.3 liters, installing a billet-steel crankshaft, and adding forged pistons attached to precision-balanced connecting rods. The intake was entirely revised, the turbos are bigger than ever, and the 12-cylinder breathes through a custom-designed sport exhaust system.

The V12 now makes 900 horsepower and 1,106 pound-feet of torque, though the latter figure is electronically limited to 885. The Rocket 900 hits 62 mph from a stop in 3.9 seconds, and it goes on to a top speed of over 217 mph if you give it enough asphalt.

Brabus went for a relatively low-key look. The Rocket 900's body kit includes a front spoiler which reduces front axle lift, surrounds for the front air intakes, mirror caps, a spoiler on the trunk lid, and an air diffuser integrated into the rear bumper. All of the add-ons are hand-crafted out of carbon fiber to keep weight in check.

The Rocket's interior is a blank canvas. Customers are encouraged to work directly with Brabus stylists to design a one-of-a-kind car.

The Brabus Rocket 900 is on sale now in Germany. Enthusiasts can buy a finished car directly from Brabus, or they can ship their stock S65 to have it transformed. Pricing hasn't been announced, but it's likely not a concern to the average Brabus buyer.
