The new Mercedes-AMG S65 Coupe has joined Brabus’ family of insanely powerful Rocket models boasting 900PS (887hp) and 1,500Nm (1,106 lb-ft) of torque, though the latter is electronically limited to 1,200 Nm (884 lb-ft).

To extract those kind of figures from the stock 630PS (621hp) and 1,000Nm (738lb-ft) 6.0-liter twin-turbo V12, Brabus increased its displacement to 6.3-liters and made all sorts of upgrades, ranging from a special billet crankshaft with longer stroke and new turbochargers to a reprogrammed ECU and a high performance exhaust.

All that power is channeled to the rear wheels via a reinforced a seven-speed automatic transmission with steering wheel paddle shifters along with a BRABUS high-performance limited-slip differential with a locking rate of 40 percent.

The new Brabus 900 Rocket Coupe promises to blast to 100km/h (62mph) in 3.7 seconds, beating the standard car by 0.4 seconds, while reaching 200km/h (124mph) in 9.1 seconds and achieving a de-restricted top speed of 350km/h (217mph).

A new suspension module that can lower the ride-height by around 15 millimeters (0.6 in) and a choice of 21-inch wheels in 255/35 ZR 21 tires front and 295/30 ZR 21 rear, or 22-inch rims in 255/30 ZR 22 tires front and 295/25 ZR 22 rear, complete the performance upgrades.

Brabus’ transformation of the Mercedes-AMG S65 Coupe concludes with a carbon fiber aerodynamic kit that includes front apron, boot lid spoiler, rear diffuser and side skirts, along with carbon fiber mirror caps and trims, and a makeover of the cabin with exclusive light brown and magnolia leather, umbra-colored wood trims, aluminum components and backlit scuff plates.

The German tuner offers the BRABUS 900 ROCKET Coupe as a complete car or as an aftermarket package for any current Mercedes-AMG S65 Coupe.

Brabus will debut the coupe alongside their new 641hp Mercedes-AMG C63S sedan tune in Geneva.
