Diesel engines
Powerful, refined and impressively fuel-efficient, the C-Class diesel engines deliver improved performance and even lower emissions, thanks to the latest in
Mercedes-Benz diesel technology.
4-cylinder diesel engines. The 4-cylinder C-Class
diesel engines offer torquey performance and
impressive responses even at low engine speeds,
while also ensuring improved fuel efficiency and
reduced CO 2 emissions.
The key to this impressive set of achievements is a
combination of advanced technologies. The engines’
fourth-generation common-rail system boasts ultraprecise
injectors, increased pressures of 2,000 bar and
further optimised combustion chambers. The higher
ignition pressure and turbocharging mean high levels
of torque are available at any engine speed, while
the twin balancer shafts ensure the engines remain
agreeably refined.
In addition, all three 4-cylinder diesel models meet
Euro 5 emissions standards and come with a variety of
innovative fuel-saving features. These include intelli gent
alter nator management that enables kinetic energy to
be used to charge the battery when coasting, a radiator
shutter that helps to reduces drag when only moderate
cooling is required, and an ECO start/stop function.
6-cylinder diesel engine. The V6-engined C 350 CDI
BlueEFFICIENCY delivers improved fuel economy
combined with enhanced performance. Thanks to
precise and fast-acting injectors, injection pressures
of up to 1,600 bar and an optimised turbocharger, it
generates a maximum 620 Nm of torque, ensuring
effortless acceleration in all situations, while output
has increased to 265 hp (195 kW). What’s more, this
most powerful of C-Class diesels also comes with
the ECO start/stop function, which helps to further
reduce fuel consumption, and meets Euro 5 emissions
regulations.
