This is the new Brabus Rocket 900. It’s a tuned version of the Mercedes-AMG GT 63 S 4MATIC+, which has been fitted with a host of engine and chassis upgrades to increase the saloon’s output to 888mph and push its top speed past the 200mph mark. 
It’s also extremely exclusive. production is limited to just 10 examples worldwide, with each model carrying a price-tag of €427,000 (almost £390,000), excluding taxes. Brabus has confirmed that it will be building right-hand-drive cars on a first-come-first-serve basis – and that the Rocket 900 will be available to purchase in the UK.

The Brabus Rocket 900 is powered by a heavily upgraded version of Mercedes-AMG’s twin- turbocharged V8 engine. The German tuning firm has enhanced the unit’s displacement from 4.0-litres to 4.5-litres, fitting a new crankshaft, larger forged pistons and stronger billet con-rods in the process.

The car’s standard twin-turbochargers have been swapped for a pair of larger ones. These major engine changes are also supported by a new carbon fibre air intake, an improved fuel system, a freer-flowing exhaust and a recalibrated ECU.

All of this implies the Brabus Rocket 900 has a maximum output of 888bhp and 1,250Nm of torque – but, to stop the gearbox from jettisoning its cogs under hard acceleration, Brabus has electronically reined back this latter figure 1,050Nm for the production version.
