You will be amazed at how versatile the CLK 220 CDI is. Not only is the engine excellent in terms of fuel economy, it is also astonishingly quiet. And the surprises don't stop there: this engine will thrill you with its powerful torque. Responsible for this all-round talent is a common rail which keeps the fuel at a permanently high pressure throughout the entire engine speed range and injects finely atomised, precisely metered quantities of fuel into the combustion chamber.
The V6 diesel engine under the bonnet of the CLK 320 CDI is also equipped with common-rail technology and has redefined standards in the CLK-Class Coupé. The engine, which has an output of 165 kW (224 hp), combines the typical economy of a diesel with the smooth running characteristics of a 6-cylinder engine.
Both engines also feature a diesel particulate filter as standard.
