2018 Mercedes-Benz GLC-Class Coupe Engine


"The 2018 Mercedes-Benz GLC offers an array of turbocharged engines, all of which feel energetic when you’re behind the wheel. The slick-shifting transmission pairs well with all of them, and the composed handling means you don’t have to fear winding roads. Still, the handling can't match some of the sharpest entries in the class." - cars.usnews

Engine and Transmission

For a luxury compact SUV, having 241 hp of power and 273 lb.-ft. of torque is great. The coupe is backed by a 2.0L inline-4 turbocharged engine. Unlike its competitors, the GLC 300 has a 9-speed automatic transmission mode. BMW X3, Audi Q5, and Lexus NX have 8-speed, 7-speed, and 6-speed automatic transmission modes, respectively. Like the GLC 300, all three of its competitors feature a 2.0L engine.
