Mercedes-Benz is delighted to announce its brand-new AMG 5.5-liter V8 biturbo powerplant, which is ready to amaze the customers with astonishing peak output figures of 571 horsepower (420 kW) and 900 Nm of maximum torque. Dubbed internally M 157, the powerful eight-cylinder unit is distinguished by many technological highlights - direct petrol injection with spray-guided combustion and twin turbochargers.

The German luxury cars manufacturer is planning to premiere the new top-performance engine in its 2010 Mercedes-Benz S63 AMG, which will hit the worldwide market this summer. Despite its strong performance values, the newly developed power unit records estimated fuel consumption of 10.5 liters per 100 kilometers (NEDC combined consumption, provisional figure). This represents a saving of 25 percent compared to the current S63 AMG. An intelligently designed power transfer plays a major part in this: the unique AMG SPEEDSHIFT MCT 7-speed sports transmission combines dynamism with economy, and includes a new start/stop function in the "Controlled Efficiency" driving mode. The new engine/transmission combination is the epitome of exclusivity, sophistication, high performance and economy.

The included S63 AMG show vehicle is a homage to the impressive history of powerful AMG V8 engines. At first glance, this top-performance saloon resembles the spectacular 300 SEL 6.8 AMG, the racing car that won a class victory and second place in the overall ranking for AMG at the 24-hour race in Spa-Francorchamps (Belgium) in 1971 – and made the company world-famous overnight.
