Mercedes-AMG GT 63 S Tuned By Brabus Could Hit 100kph In 2.8 Seconds

Author: |

This week was so special for people who love tuning and horsepower as Brabus introduced its latest Rocket based on the 2021 Mercedes-AMG GT 63 S 4 Matic+.

Technical Improvements

As you know, Mercedes-AMG GT 63 S 4Matic+ has a 4.0-liter twin-turbo V8 engine as standard with 639 hp and 900 nm of torque, but Brabus increased the engine displacement to 4.5-liter at the first step by by increasing the the strock to 100 mm and the cylinder bore to 84 mm. Then they used larger forged pistons, bespoke billet piston rods and a bespoke precision-balanced billet crankshaft. Brabus also fitted a new set of turbochargers with a larger compressor that can provide the maximum boost pressure of 1.4 bar. Other technical highlights are a carbon fiber ram-air intake system, upgraded ECU and high-performance stainless steel exhaust system with electronically controlled adjustable exhaust flaps.

Brabus Rocket

As a result, the Brabus Rocket 900 now has 888 hp at 6,200 rpm and 1,250 nm of torque at just 2,900 rpm. In order to save the drivetrain parts, Brabus electronically limited the maximum torque to 1,050 nm.

Brabus Rocket 900 can hit 100 kph in 2.8 seconds and then hit the top speed of 330 kph. Its 0-200 kph acceleration takes only 9.7 seconds and to reach 300 kph from standstill it needs just 23.9 seconds.


Brabus also installed a wide body kit on the Rocket 900 that include wider fenders at the rear, multi-piece carbon fiber rear wing, and a rear diffuser. There are new set of 21 and 22-inch wheels as well that are called Brabus Monoblock Z Platinum Edition.


Brabus Rocket 900 production is limited to only 10 examples each cost €427,000.
