The Brabus 900 engine conversion unleashes the performance reserves in the twin-turbo V12 of the G65. The power unit is thoroughly revised in the Brabus engine shop equipped with state-of-the-art machining equipment.
The installation of a billet-steel Brabus special crankshaft with longer stroke in combination with enlarged cylinder bores, the matching forged pistons and precision-balanced billet-steel conrods increases the displacement from stock 6.0 to 6.3 litres.
The modifications to the engine peripherals also play a major role in the tremendous power output. The engine uses modified exhaust manifolds, and the two production turbos are replaced by Brabus turbos with larger compressor unit and turbine, which produce a higher boost pressure than the production components. The conversion also includes larger downpipes with a diameter of 80mm, free-flow metal catalysts and a Brabus stainless high-performance exhaust system with actively controlled exhaust flaps.
As the result of the extensive modifications, the Brabus Rocket 900 6.3 V12 twin-turbo engine produces unparalleled performance figures. The rated output of 900bhp is produced at a low 5500rpm, and even more gigantic is the peak torque of 1500Nm at 4200rpm (electronically limited to 1200Nm in standard spec).
In combination with the 7-speed automatic transmission and permanent all-wheel-drive, the Brabus 900 “One of Ten” shoots to 100km/h in just 3.9 seconds. The top speed is limited electronically to 270km/h.
At these speeds, a wider track optimises the handling and safety, and consequently the new super-SUV is fitted with the thrilling Brabus Widestar bodykit. The strikingly styled fender flares add 120mm to the width of the body and, as a result, offer plenty of space for massive 23-inch forged wheels. In these king-sized wheels is space for the largest braking system ever designed for an SUV.
The Brabus 900 “One of Ten” is a strictly limited edition of just 10 cars, priced at 666,000 euros each.
