Based on the current C-Class, the rounded GLC replaces the GLK. Plush furnishings inside the quiet cabin are very appealing, although it also has Mercedes' complex infotainment system. The 241-hp, 2.0-liter turbo four-cylinder delivers ample power, and is matched to a nine-speed automatic that shifts smoothly and in a timely manner. Overall fuel economy was 22 mpg. The GLC rides comfortably and handles with athleticism. The seats are very comfortable all around, although the rear seats are a bit snug. Forward collision warning with automatic braking is standard. New for 2018 is the 350e Plug-in hybrid. Updates for 2022 include standard adaptive high-beam assist, and the 350e was discontinued.
