Mercedes E63 AMG sedan to 850 PS By Brabus

The Mercedes E63 AMG isn't lacking in terms of power but that hasn't stopped Brabus from unveiling their latest 850 6.0 Biturbo.

Under the hood as the twin-turbo 5.5-liter V8 engine has been bored out to displace 5.9-liters (5,912 cc). The company then installs a billet crankshaft, forged billet pistons, billet piston rods and optimized cylinder heads. The tuning firm also adds a new intake manifold, upgraded turbochargers, a high-performance exhaust system and an optimized ECU.

Thanks to these modifications, the engine develops 850 PS (625 kW) and an electronically limited 1,150 Nm (848 lb-ft) of torque. It is connected to a modified seven-speed MCT SPEEDSHIFT transmission which enables the car to accelerate from 0-100 km/h in 3.7 seconds or 3.1 seconds when equipped with 4MATIC all-wheel drive. Depending on the tires, final drive ratio and the programming of the Vmax unit, the top speed ranges from 300 km/h (186 mph) to more than 350 km/h (217 mph).
