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, but other safety gear like blind-spot monitoring and cross-traffic alert comes in confusing options packages.
