The further advanced four-cylinder diesel engine with a displacement of 2.2 litres is eco-friendly and powerful. In the new C-Class Coupé it produces outputs of 125 kW/170 hp and 150 kW/204 hp. Both variants are equipped with SCR technology (Selective Catalytic Reduction) for emission control, which makes especially environmentally friendly driving possible.

 
In addition, four petrol engines are initially available. The output spectrum ranges from the 1.6-litre four-cylinder engine in the C 180 rated at 115 kW/156 hp to the two-litre C 200 (135 kW/184 hp) and C 250 (155 kW/211 hp) models and the C 300, likewise with a displacement of two litres but with an output of 180 kW/245 hp.

All four-cylinder engines share the third-generation direct injection system with spray-guided combustion. The system pressure is up to 200 bar with the pressure being variably optimised in line with the engine mapping. Piezo injectors enable optimal mixture formation with up to five injections per power stroke.

This technology is rounded out by the rapid multi-spark ignition (MSI), which is able to trigger up to four sparks a millisecond as required. The interplay of both technologies enable outstanding fuel utilisation with minimal emissions.

The thermal management system with on-demand water pump also operates efficiently.

 
Optimised powertrain for more comfort and efficiency

Power is sent to the road via either a 6-speed manual transmission, the 7G-TRONIC PLUS 7-speed automatic transmission or the new 9-speed 9G-TRONIC. Both automatic transmissions are equipped with the DIRECT SELECT selector lever and DIRECT SELECT paddle shifters.
