Mercedes-Benz GLC-Class vs. BMW X3
Luxury becomes personal the moment you settle into the driver’s seat. The screen you glance at, the response as you accelerate, the confidence of having all-wheel drive already included: those details shape your experience long after the first impression. For drivers around Rochester Hills, Rochester, and Troy, Michigan, they also bring practical value to changing seasons and everyday travel.
At BMW of Rochester Hills, our Mercedes-Benz GLC-Class vs. BMW X3 comparison focuses on the 2026 BMW X3 30 xDrive and 2026 Mercedes-Benz GLC 300 SUV. Keep reading to explore how their power, technology, efficiency, and towing capabilities translate into your time behind the wheel.
Power and Drivetrain
Both SUVs bring 255 horsepower to the conversation, so the distinction starts with how that power reaches the road. The BMW X3 30 xDrive includes xDrive all-wheel drive as standard equipment. The Mercedes-Benz GLC 300 comes standard with rear-wheel drive, with all-wheel drive offered through the GLC 300 4MATIC configuration. For a Michigan shopper who already considers AWD essential, the BMW includes that priority at the starting point.
Picture a cool morning with damp pavement or the arrival of the season’s first snowfall. The BMW’s xDrive system can distribute power between the axles to support traction as conditions change.
Fuel Efficiency
Your next SUV will likely spend plenty of time on familiar roads: commuting, making appointments, and heading home after dinner. That’s why comparing the EPA-estimated fuel economy of the BMW X3 and Mercedes-Benz GLC-Class can help you determine which SUV better fits your daily driving needs and priorities.
| Fuel Economy | 2026 BMW X3 30 xDrive* | 2026 Mercedes-Benz GLC 300 RWD** |
City MPG | 27 MPG | 24 MPG |
Highway MPG | 33 MPG | 32 MPG |
The BMW leads in both figures while also including all-wheel drive. You can choose the X3 for its standard drivetrain and still benefit from higher estimated fuel economy in this comparison.
Cabin Technology
The two cabins express modern luxury through different screen layouts. The BMW X3 features a 14.9-inch central touchscreen within the BMW Curved Display, complemented by the BMW Interaction Bar.
The Mercedes-Benz GLC 300 uses an 11.9-inch portrait-oriented central touchscreen. BMW’s larger screen creates a broad digital focal point across the dashboard, while Mercedes-Benz takes a more vertical approach through the center console.
In the X3, that presentation comes with several ways to interact with vehicle functions, including the touchscreen, iDrive controller, and voice commands through the BMW Intelligent Personal Assistant. You can explore navigation before departure, select your music, and get familiar with the controls that suit you.
Towing Capability
An SUV can look equally appropriate outside a restaurant and beside a trailer at the start of a weekend away. The X3 30 xDrive can tow up to 4,001 pounds when properly equipped with the factory-installed trailer hitch. The Mercedes-Benz GLC 300 offers up to 3,500 pounds when properly equipped. That gives the BMW a 501-pound advantage in maximum rated towing capacity.
For someone considering a small camper, utility trailer, or personal-watercraft trailer, that additional capacity may expand the combinations worth exploring.
