Powerplants with relaxing properties
The 6 - cylinder common - rail diesel engine in
the CLS 320 CDI makes every drive an enjoyable
journey. A whole array of new features, such as
the leading - edge piezo injectors, ensure among
other things that the fuel is metered with ultra -
high precision and that the injection timing is
extremely accurate. Improved air ducting has
enhanced the engine’s smoothness still further.
Moreover, it meets the EU 4 exhaust emissions
standard by a considerable margin, and the
standard - fitted diesel particulate filter eliminates
about 95 % of the particulates from the exhaust.
The 6 - cylinder direct - injection petrol engine
under the bonnet of the CLS 350 CGI uses a piezo
injector which injects the fuel into the centre of
the combustion chamber. This improves mixture
formation, resulting in virtually complete combustion
with low pollutant emissions. The engine’s
215 kW (292 hp) are delivered seamlessly, with
torque peaking at 365 Nm.
The V8 engine in the CLS 500 impresses with
its smoothness and dynamic power output. Its four
valves per cylinder combine with the continuous
camshaft adjustment on the inlet and exhaust
sides to produce the engine’s mighty output of
285 kW ( 388 hp ) .
