Petrol engines
Innovative engine technology enables the petrol C-Class models to achieve even greater levels of fuel efficiency and emit less CO 2 than ever.
4-cylinder petrol engines. Direct petrol injection,
variable valve control and turbocharging help the optimised
4-cylinder petrol engines to deliver high levels
of power and torque along with low fuel consumption
and emissions.
More complete combustion and variable valve control
ensure these innovative engines use fuel more
efficiently, while weight-savings and lower internal
friction help to further reduce their fuel consumption.
Both 4-cylinder C-Class petrol engines feature twin
balancer shafts for optimum refinement and meet the
stricter Euro 5 emissions standards.
6-cylinder petrol engine. With a fuel saving of 20%
when compared to its predecessor, the new C 350
BlueEFFICIENCY 6-cylinder outperforms on both
levels: lower emissions and yet more torque. Again,
Mercedes-Benz have continued to improve on their
direct-injection technology to achieve an output of
306 hp (225 kW). For this particular engine another
development has helped create one of the most
efficient 6-cylinder petrol engines in its class so far:
the ECO start/stop function. With this standard feature
an entirely new emissions and air circulation system
has come into being, aided not only by intelligent
generator management and but also by tweaks to
overall engine management. Equally impressive is the
formidable smoothness of this engine.
The following C-Class petrol models are available:
– C 180 BlueEFFICIENCY 156 hp (115 kW) and 250 Nm
– C 250 BlueEFFICIENCY 204 hp (150 kW) and 310 Nm
– C 350 BlueEFFICIENCY 306 hp (225 kW) and 370 Nm¹
