The Brabus 850 6.0 Biturbo is the spiritual successor to the legendary Brabus 800 E, a V12 animal that loved nothing more that to chew and spit out tyres for breakfast! This, the 850, features an uprated V8 engine, now 5.9 litres rather than the serial 5.5 litres that the standard AMG car is fitted with.
To achieve this, Brabus uses precision-balanced billet crankshaft with a stroke of 96 mm (3.78) instead of the standard 90.5 millimeters (3.56 in.) in concert with special forged billet piston rods. The engine also receives new turbochargers with larger compressor units and a special manifold. A high-performance exhaust system and an ECU optimisation are both included in the package.
As a result, power is now 850 hp with torque limited to 1,150 Nm (still plenty to spin up the rear-wheels in most gears! The power is routed through a strengthened 7-speed sports transmission with rear-wheel drive and 4MATIC version both available. With the rear wheel drive version the sprint to 100 km/h is achieved in just 3.7 seconds whilst the 4MATIC version reaches that figure in a staggering 3.1 seconds. Brabus’ VMax system limits the Brabus 850 6.0 Biturbo to speeds between 300 km/h and more than 350 km/h.
