Impressive performance.

At Mercedes-Benz, enthusiasm and efficiency are a great fit even in a SUV. The proof: The petrol engines of the new Mercedes-Benz GLS.They do their job at exceptional fuel consumption levels offering unbridled motoring enjoyment. Simply impressive.

V6 petrol engine
The highlights

When designing this engine particular importance was attached to making it compact and lightweight. Coupled with measures intended to optimise friction characteristics, this leads to low fuel consumption and moderate emissions. This engine relinquishes neither its high power output, nor its powerful torque.

V8 petrol engine
The highlights

This engine is responsive and produces an optimum torque level from low engine speeds. Enhanced consumption, low emissions and good cold-running characteristics also contribute to the engine's excellent efficiency.

AMG 5.5 litre V8 twin turbo engine
The highlights

The combination of biturbo charging and direct injection burns the fuel particularly effectively in this agile, torque V-engine with offset crankshaft. The result: lower fuel consumption but the usual high AMG engine power.

Details on the engine technology

Extremely rapid-action, precise piezo injectors spray the fuel into the combustion chambers, ensuring a homogeneous air-fuel mixture cloud. The oil pump with requirement-oriented control cools and lubricates the assemblies in line with engine load and speed.

Details on efficiency

Optimised air and exhaust systems, controlled ancillaries, intelligent alternator management and lightweight design ensure good emission and consumption levels. The standard ECO start/stop function switches off the engine temporarily when the vehicle is stationary.
