Brabus has unveiled its new Mercedes-AMG S65 Cabriolet-based 900 Rocket Cabrio – the fastest, most powerful convertible in the world.

Unlike many aftermarket tuning companies, Brabus doesn’t install an exhaust and an ECU tune on a car and call it a day. Similar to many other Brabus creations, the Rocket 900 Cabrio is a very serious and complete package. The 6.0-liter V12 was bored out to 6.3-liters and larger turbochargers and bespoke exhaust manifolds were also installed. A heavily revised cooling system was required to help keep the temps down, while a revised ECU helps to manage everything. The result? A frankly shocking 888 horsepower and 1,106 lb-ft of torque.

Of course, Brabus had to make thorough revisions to the seven-speed transmission to ensure it didn’t fail spectacularly upon unleashing that mountain of torque. A new limited slip differential was also installed. The German tuning company says the drop-top will accelerate from 0-62 mph in 3.9 seconds, but that’s nothing compared to the top speed. This mad creation will keep accelerating all the way to a hypercar-rivaling, vision blurring 217 mph.

Brabus’ S65 Cabriolet upgrades aren’t exclusive to the powertrain. The company has also developed a subtle aero kit for the car and 21-inch or optional 22-inch lightweight forged wheels. Brabus branding is just about everywhere in the cabin, while a new 250 mph speedometer was installed for those high-speed autobahn blasts.

The Brabus 900 Rocket Cabrio will be shown for the first time at the 2017 Frankfurt Motor Show later this month.

    wait till GAD-Motors gets their hands on it. In 2012; they tuned a Brabus Bullit into an everyday 240MPH 4-door automatic grocery getter that can hang with the Veyron.
