Safety
Driving pleasure and efficiency can be reconciled by means of engine technologies which are impressively powerful but at the same time keep fuel consumption
and CO 2 emissions low
V6 engine. The BlueDIRECT petrol engines were developed
with the aim of substantially reducing fuel consumption
and emissions without compromising on dynamism and
ride comfort. The result: state-of-the-art engine technology
which offers effortlessly superior performance yet also
takes a responsible approach to fuel consumption.
Factors contributing to the reduction in fuel consumption
comprise the enhanced combustion process, the
standard-fit ECO start/stop function, a new intake and
exhaust system, regulated ancillaries, intelligent
alternator management and the consistent use of
lightweight construction principles. The excellent
refinement of the V6 engine is particularly impressive.
A 25% reduction in fuel consumption compared with the

predecessor model and correspondingly lower CO 2 emis-

sions are reconciled with enhanced dynamism in the
ML 350 4MATIC BlueEFFICIENCY. These benefits are due

principally to the current generation of direct-injection
petrol engines from Mercedes-Benz which operates using
spray-guided combustion and high-pressure injection via
piezo injectors. The maximum output is 225 kW (306 hp),
