A coupelike SUV, the GLC Coupe, is based on the rounded GLC that replaced 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. We got an overall 22 mpg overall when we tested the GLC. 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. A high-performance AMG model, powered by a turbocharged V6 engine, is also available.
