In addition, a new generation of four-cylinder engines is celebrating its premiere whose unique TWINPULSE system sets new standards in this displacement class in terms of output and torque characteristics, smooth running and fuel consumption. Two four-cylinder models are available: the CLK 200 KOMPRESSOR (120 kW/ 163 hp) with conventional fuel injection and the CLK 200 CGI (125 kW/170 hp) with direct petrol injection. The TWINPULSE system features a combination of different technologies which ensure a high level of driving pleasure together with a low fuel consumption and the smoothness of a six-cylinder engine: balancer shafts, supercharger, intercooler, variably adjustable camshafts and four-valve technology.
In the new CGI engine Mercedes-Benz combines the TWINPULSE system with a pathfinding direct petrol injection system which reduces fuel consumption to just 7.9 litres per 100 kilometres (NEDC overall consumption). This is a reduction of approx. 16 percent versus the preceding model. The new CLK 200 KOMPRESSOR has a fuel consumption of 8.6 litres per 100 kilometres (NEDC overall consumption) and is therefore approx. 8.5 percent more economical than before.
Mercedes-Benz has extended the range of six-cylinder models in the new CLK-Class with the well-proven 2.6-litre engine generating 125 kW/170 hp. The potent 3.2-litre V6 power unit (160 kW/218 hp) remains unchanged. A new entry in this coupé class is the powerful diesel model CLK 270 CDI, whose bonnet conceals an ultra-modern five-cylinder diesel engine with common-rail fuel injection. This has an output of 125 kW/170 hp and is one of the most economical engines in its class with a fuel consumption of only 6.7 litres per 100 kilometres (NEDC overall consumption).
