The Mercedes-Benz CLK-Class is a series of mid-size luxury coupés and convertibles produced by German car manufacturer Mercedes-Benz in two generations. Although its design and styling was derived from the E-Class, the mechanical underpinnings were based on the smaller C-Class, i.e. respectively based on the W202 and W203 platforms of the C-Class. It was positioned below the Mercedes-Benz CL-Class and SL-Class, but above the SLK-Class. The CLK name derives from the German Coupé Leicht Kompakt (or Kurz), translated Coupé-Light-Short. In 2009 Mercedes ceased to use the CLK designation moving the segment designation back to E-Class Coupe/Convertible instead, as it had called this specific line of its vehicles previously before the CLK moniker was introduced in 1997.
