GLC 300 and GLC 300 4MATIC
The 2.0-liter turbocharged inline-four teams with an Integrated Starter-Generator and a 48-volt battery, which adds up to 23 horsepower and 148 lb-ft of gas-free assist for swift response, according to Mercedes-Benz USA.
Power runs through the 9G-TRONIC nine-speed automatic to the rear wheels, or to all four wheels with 4MATIC all-wheel drive. For a closer look at the all-wheel-drive hardware, see our guide to how 4MATIC all-wheel drive works.
GLC 350e 4MATIC Plug-In Hybrid
The GLC 350e pairs the same 2.0-liter turbocharged engine with an electric motor. Mercedes-Benz USA describes it as an SUV you can drive as an EV for around-town commuting and as a turbocharged SUV for long distances.
Mercedes-AMG GLC 53 4MATIC+
The AMG-enhanced inline-six adds an electric auxiliary compressor to its hybrid assist, and a 10-second overboost raises torque to 472 lb-ft. Power flows through an AMG SPEEDSHIFT MCT 9-speed transmission to AMG Performance 4MATIC+ all-wheel drive, which can vary front-to-rear torque distribution, per Mercedes-Benz USA.
Looking for a fully electric GLC?
The 2027 Mercedes-Benz GLC 400 4MATIC Electric is a separate all-electric model. Mercedes-Benz USA lists dual motors producing 483 horsepower, a 94-kWh usable battery, DC fast charging up to 330 kW that goes from 10 to 80 percent in about 22 minutes, and an EPA-estimated range of up to 350 miles (331 miles with all-season tires).
EPA-estimated fuel economy figures are for comparison purposes only. Your actual mileage will vary depending on driving conditions, how you drive and maintain your vehicle, battery age/condition, and other factors.
GLC 350e Electric Range and Charging
The GLC 350e runs on battery power alone before switching to hybrid operation. For drivers commuting from Bonita, a shorter daily round trip may fit entirely within its electric range.
| Item | Rating |
|---|---|
| EPA-estimated all-electric range | 54 miles |
| AC charging (11-kW onboard charger) | 10% to full in under 3 hours |
| DC fast charging (standard 60 kW) | 10% to 80% in about 20 minutes |
