Mercedes-Benz has paid particular attention to further development of the four-cylinder engines. In the petrol range, the output of the entry-level C 180 KOMPRESSOR has increased from the previous 105 kW/143 hp to 115 kW/156 hp, with maximum torque improved by 4.5 percent from 220 to 230 newton metres, while the C 200 KOMPRESSOR develops 15 kW/20 hp more than before. It has an output of 135 kW/184 hp and generates its maximum torque of 250 newton metres from 2800 rpm. These modified engines considerably improve the performance and fuel consumption of the four-cylinder models. When accelerating from standstill to 100 km/h, the C 200 KOMPRESSOR is 0.5 seconds faster than its predecessor. Improvements in fuel consumption are equally impressive: the C 180 KOMPRESSOR consumes 0.3 litres per 100 kilometres less than before, while the combined fuel consumption of the C 200 KOMPRESSOR has been reduced by 0.5 litres per 100 kilometres.
Fuel consumption of the four-cylinder CDI engines reduced by 0.3 lilitres
Further development of the four-cylinder units was also the main focus for the diesel engines. The engineers in Stuttgart have made further improvements to the engine, turbocharger and common-rail direct injection, modifying more than 90 components. As a result of these measures the new C 200 CDI has eleven percent more output than the preceding model, with 100 kW/136 hp versus the previous 90 kW/122 hp. The C 220 CDI develops a peak output of 125 kW/170 hp (previously 110 kW/150 hp), and generates a torque of 400 newton metres from 2000 rpm - around 18 percent more than before. Fuel consumption has been reduced by up to 0.3 litres per 100 kilometres: in the New European Driving Cycle (NEDC), the C 200 CDI and C 220 CDI are able to travel 100 kilometres on just 6.1 litres of fuel.
The modern V6-engines in the C-Class range remain unchanged, with a choice of three petrol units developing 150 kW/204 hp, 170 kW/231 hp and 200 kW/272 hp. The six-cylinder of the new C 320 CDI has an output of 165 kW/224 hp. With the exception of the C 350, all models in the new C-Class are equipped with a six-speed transmission featuring AGILITY CONTROL gearshift as standard. The top-of-the-range C 350 has 7G-TRONIC, the world’s only seven-speed automatic transmission, as standard equipment. This is also available for the other six-cylinder C-Class models on request.
