BlueEFFICIENCY includes a series of innovative environmental technologies, such as intelligent energy management, improved aerodynamics and tyres with low rolling resistance. The vehicles consume less fuel but do not compromise on performance, safety or comfort.

The dynamic V6 diesel engine for the GL 350 CDI 4MATIC BlueEFFICIENCY delivers a full 165 kW power output with a maximum torque rating of 510 Nm in the engine speed range 1600 to 2800 rpm.

Implementing BlueTEC catalytic converter technology, the GL 350 BlueTEC 4MATIC combines an impressive 155 kW output and maximum 540 Nm torque rating with economical consumption and low emissions. First, carbon monoxide, hydrocarbons and particulate emissions are reduced by a combination of oxidation catalytic converter and particulate filter. Next, AdBlue® comes into play: the fluid is injected into the exhaust system where, under the effect of the exhaust gas heat, ammonia is formed. This ammonia then reduces the nitrogen oxides in the downstream SCR catalytic converter by eighty per cent. Essentially, all that remains is water, nitrogen and carbon dioxide (CO2) – the final product of complete combustion. In short: BlueTEC is an extremely clean diesel technology and the BlueTEC model is one of the few vehicles to comply with the strict EU 6 emissions standard.

The GL 450 CDI 4MATIC is powered by a V8 diesel engine with 4-valve technology and common rail direct injection. 225 kW output and a maximum torque of 700 Nm ensure sporty performance combined with attractive fuel consumption.
