The 2017 Mercedes-AMG S65 Cabriolet is no doubt a powerful car, with a 621 horsepower engine under its hood. Despite its power, Brabus still decided that they'd push the S65's V12 engine even further. By doing so, they were able to extract an additional 267 horsepower, giving it a total of 888 horsepower (662 kilowatts) available from 5,500 rpm. Naturally, torque is also increased to 1,106 pound-feet (1,500 Nm) at 4,200 rpm from only 738 pound-feet (1,000 Newton metres). To preserve reliability, it had to be electronically capped to 885 pound feet (1,200 Nm).
With that much power hike, Brabus didn't just have to do some software revision, but they also had to increase engine displacement from 6.0 to 6.3 liters and enlarge the cylinder bores. Exhaust manifolds and larger turbochargers had to be installed too. The new control system takes care of cooling and stabilizing the car, making it work in the most efficient way while ensuring you get a smooth V12 cabriolet.
Brabus modified a seven-speed automatic transmission that works with the immense power of the V12, giving power to the rear wheels. It has been given a custom limited-slip differential, new intake manifold, bigger down pipes, and a high-performance exhaust that completes the hardware upgrades.
After the upgrade, the Brabus Rocket 900 Cabrio is now able to do the 0 to 62 miles per hour (100 kilometers per hour) sprint in 3.9 seconds; that makes it two tenths of a second quicker than the regular S65 Cabrio. The standard version has a top speed of 155 mph (250 kph), and with the optional driver’s pack, it can go up to 186 mph (300 kph), but this black example in the photo can go on with a top speed of 217 miles per hour (350 kilometers per hour).
Moving on to the exterior design, the Brabus S65 Cabrio now has a subtle aerodynamic kit. You can also tell in the photos that it was given a set of 21-inch wheels, covered in low-profile tires, but this can be swapped with a set of 22-inch alloy wheels as an option. Furthermore, it has a lowering module that lowers the overall suspension making it 0.6 inches closer to the road.
As for the interior, it now has a new digital speedometer with a maximum of 400 kph (250 mph). New LED ambient lighting, an illuminated Brabus logo, and aluminum bits and pieces have been added as well.
The company says that when they unveil the new S65 Cabriolet with OLED lights at 2017 Frankfurt Motor Show, we should also see the Rocket 900 Cabrio in a two-tone Mondial Vanilla and Mondial Black leather interior.
