Optimized gasoline engines

Performance and agility matched with high fuel economy – this was the objective in the ongoing development of CGI (stratified charged gasoline injection) engines for Mercedes-Benz passenger cars. The CGI process enhances combustion efficiency. The precisely metered quantity of gasoline required in a given driving situation is injected into the cylinders.

In May 2010, Mercedes-Benz reached a new milestone in efficiency: Thanks to further innovations such as third-generation direct injection, a fully variable valve train, new combustion processes, and a multi-spark ignition, the new BlueDIRECT V6 and V8 engines consume up to 24 percent less fuel than their predecessors, despite generating greater power and torque.

Further savings will be made in future with fuel-efficient stratified combustion processes, reduced friction within the engine, and lower power consumption in the auxiliary units. In the absolute top segment, the CLS 63 AMG is setting standards with the new AMG V8 biturbo engine. Its key data: 5,461 cc displacement, a maximum output of 386 kW (525 hp) and 700 newton-meters of torque, and fuel consumption of only 9.9 liters per 100 kilometers (fuel consumption combined cycle)* with CO₂ emissions of 231 g / km (CO₂ emissions combined, energy efficiency class: F)*. With these figures, the CLS 63 AMG not only significantly undercuts the values of all its direct competitors, but is also more fuel-efficient than much less powerful vehicles.
