Brabus has revealed its take on the Mercedes-AMG GT63 S, boosting the already-rapid four-door model’s peak power to a whopping 662 kW.
Dubbed the Brabus Rocket 900, just ten examples of the tuned GT63 S will be produced, each wearing an eye-catching widebody kit.
The German tuner says it has increased the twin-turbo 4,0-litre V8’s displacement to 4,5 litres and added a new high-performance forced-induction system. The result (together with some serious ECU fettling, we'd presume) is 662 kW and a whopping 1 250 N.m (though the latter figure is limited to 1 050 N.m in most driving scenarios to "protect the drivetrain").
The result of all that extra oomph? Well, working with Benz’s nine-speed sports transmission and 4Matic+ all-wheel-drive system, Brabus says the Rocket 900 will hit 100 km/h from standstill in just 2,8 seconds, some four-tenths quicker than standard. The tuned vehicle will reach 300 km/h in a claimed 23,9 seconds, with its top speed electronically limited to 330 km/h “due to the tyres”.
Speaking of rubber, the “extremely wide” Monoblock Z wheels (measuring 21 inches fore and 22 inches aft) are wrapped in “high-performance” tyres from Pirelli.
