The Mercedes-Benz GLK-Class is a series of five-door compact luxury SUV's that were produced from 2008 to 2015 by German automaker Mercedes-Benz. The GLK-Class was essentially an updated version of the earlier M-Class, boasting a new design and improved engines and suspension. The lineup included both gasoline- and diesel-powered models, with features such as seven-speed automatic transmissions, active suspension, and 4MATIC all-wheel drive. While production ended in 2015, the GLK-Class was replaced by the GLC-Class in 2016.
