Brabus uncovers the ballistic 850 6.0 Biturbo, packing 838bhp and 1,450Nm of torque

Mercedes’ aftermarket tuning arm Brabus, has got its hands on the already powerful E63 AMG and added a whole lot more performance. Called the Brabus 850 6.0 Biturbo, it’s available as a saloon or estate and powered by an uprated 6.0-litre twin-turbo V8, which sees power soar from 550bhp to 838bhp.

Brabus has been tuning the Mercedes E-Class for almost two decades, with this fifth-generation Brabus model being the first to use eight cylinders instead of twelve. The substantial power hike has been made possible by increasing engine displacement from 5.5 litres in the standard E63 to 6 litres in Brabus 850. A new crankshaft, larger turbos and forged piston rods also contribute to the power boost.

The amount of torque developed from the new 6.0-litre engine has more than doubled over the donor car’s 720Nm output. Now at 1,450Nm, Brabus has had to limit the figure to 1,150Nm in showroom models to help reduce stress on the entire drivetrain.

Other upgrades include a Brabus high-performance exhaust system, which emerges from the carbon fibre rear diffuser. The system is equipped with active butterfly valves, which help mute the engine note by selecting ‘Coming Home’ mode and give the full-blooded V8 soundtrack by selecting ‘Sport’.

The Speedshift MCT seven-speed gearbox has also been modified to help manage the hike in power. Both rear and 4 MATIC all-wheel drive version of the Brabus 850 are available, each capable of a 0-62mph sprint in 3.7 seconds and 3.1 seconds respectively. Depending on tyres, 217mph is achievable.

Inside, quilted leather upholstery on the seats, door card and foot wells can be finished in any colour, with steering-wheel mounted aluminium shift paddles also added. The Brabus 850 6.0 Biturbo can be order as a complete car or the tuning firm can convert any existing Mercedes E63 to the same specification.
