The 2018 Mercedes-Benz GLC has four powertrain configurations unique to each of the four trims. Only the base trim has the rear-wheel drive available aside from all-wheel drive. The hybrid powertrain uses a seven-speed automatic transmission while the rest have a nine-speed automatic transmission. The Mercedes-Benz GLC 300 is powered by a 2.0 liter turbocharged inline-4 engine producing 241 horsepower and 273 lb. ft. of torque. The GLC 350e is a hybrid of the aforementioned 2.0 liter engine and electric motors with a total output of 315 horsepower and 413 lb. ft. of torque. The AMG-badged models have more power under the hood and the starter Mercedes-AMG GLC 43 has a 3.0 liter turbocharged V6 producing 362 horsepower and 384 lb. ft. of torque. Next is the AMG GLC 63, which has a 4.0 liter turbocharged V8 producing 469 horsepower and 479 lb. ft. of torque. Even with the base four cylinder engine, there is more than enough oomph under the hood to overtake at speed without a hitch. It took 6.4 seconds to launch the SUV to 60 mph, a decent performance in the compact SUV segment. The turbo powerplant is tuned for responsiveness that bodes well in street use. As one of the smallest SUV bodies in Mercedes’ offerings, the GLC handled well for its size. It sure-footed through the turn and body roll is minimized with its fairly low stance. The steering is responsive but surprisingly light that almost seems disconnected from the pavement. A sportier driving mode however was the remedy and there is just the right amount of weight added. Braking from 60 mph took 116 feet, slightly more than the average in its class. Stopping power however did not feel lacking and although the pedal stroke is longer, it is easy to control in start-stop situations in busier streets.
