The Mercedes-Benz C 220 CDI BlueEFFICIENCY model with ECO start/stop function and a six-speed manual transmission – the most fuel-efficient C-Class of all time.

The engine is stopped automatically when the car is coasting up to traffic lights – as soon as its speed falls below 8 km/h, and once the driver has applied the brakes and moved the gear lever to neutral. The engine starts again immediately when the driver presses the accelerator or clutch pedal. Availability of the ECO start/stop function is indicated on the instrument cluster. The C 220 CDI BE has a displacement of 2143 cc, an output of 125 kW (170 hp) and a peak torque of 400 Nm, allowing the Saloon to accelerate from 0 to 100 km/h in 8.4 seconds. Yet its combined fuel consumption is just 4.4 litres per 100 kilometres – 0.4 litres lower than previously – meaning that its CO2 emissions have been reduced from 127 g/km to 117 g/km. The C 220 CDI BlueEFFICIENCY model with ECO start/stop function is available from autumn 2010.
