Compare the2025 BMW X6VS 2025 Mercedes GLC Coupe

The BMW X6 has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags help prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The GLC Coupe doesn’t offer a front passenger side knee airbag.

In a Vehicle-to-Vehicle Frontal Crash Prevention 2.0 test conducted by the Insurance Institute for Highway Safety (IIHS), the BMW X6 achieved a “Good” rating - the highest possible - for its performance in forward collision warning and automatic braking systems, demonstrating its excellent capabilities in preventing collisions. The Mercedes GLC Coupe has not been tested.

The X6’s standard lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. A lane departure warning system costs extra on the GLC Coupe.

Both the X6 and the GLC Coupe have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, all wheel drive, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, post-collision automatic braking systems, daytime running lights, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors and available around view monitors.

The BMW X6 weighs 714 to 1012 pounds more than the Mercedes GLC Coupe. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.

The X6’s corrosion warranty is 7 years longer than the GLC Coupe’s (12 vs. 5 years).

BMW pays for scheduled maintenance on the X6 for 3 years and 36,000 miles. BMW will pay for oil changes, tire rotations, air filter replacements, cabin filter replacement, brake fluid replacement, inspections, and any other required maintenance. Mercedes doesn’t pay scheduled maintenance for the GLC Coupe.

J.D. Power and Associates’ 2024 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that BMW vehicles are more reliable than Mercedes With 28 fewer problems per 100 vehicles in the first three years of ownership, J.D. Power ranks BMW higher than Mercedes.

The X6 xDrive40i’s standard 3.0 turbo 6-cylinder hybrid produces 120 more horsepower (375 vs. 255) and 103 lbs.-ft. more torque (398 vs. 295) than the GLC Coupe’s 2.0 turbo 4-cylinder hybrid. The X6 M60i xDrive’s standard 4.4 turbo V8 hybrid produces 268 more horsepower (523 vs. 255) and 258 lbs.-ft. more torque (553 vs. 295) than the GLC Coupe’s 2.0 turbo 4-cylinder hybrid.

The X6 has 5.5 gallons more fuel capacity than the GLC Coupe (21.9 vs. 16.4 gallons), for longer range between fill-ups.

The X6’s launch control uses engine electronics to hold engine RPM’s precisely in order to provide the most stable and rapid acceleration possible, using all of the available traction. The GLC Coupe doesn’t offer launch control.

For better stopping power the X6’s brake rotors are larger than those on the GLC Coupe:

For better traction, the X6 has larger standard tires than the GLC Coupe (275/45R20 vs. 235/55R19). The X6’s optional tires are larger than the largest tires available on the GLC Coupe (F:275/40R21 & R:315/35R21 vs. F:255/45R20 & R:285/40R20).

The X6’s standard tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the GLC Coupe’s standard 55 series tires. The X6’s optional 275/35R22 front and 315/30R22 rear tires have a lower 35 series front and 30 series rear profile than the GLC Coupe’s optional 40 series front and 35 series rear tires.

For better ride, handling and brake cooling the X6 has standard 20-inch wheels. Smaller 19-inch wheels are standard on the GLC Coupe. The X6’s optional 22-inch wheels are larger than the 21-inch wheels optional on the GLC Coupe.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires available on the X6 can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The GLC Coupe doesn’t offer run-flat tires.

The X6 M60i offers active sway bars, which help keep it flat and controlled during cornering, but disconnect at lower speeds to smooth the ride and offer greater off-road suspension articulation. This helps keep the tires glued to the road on-road and off. The GLC Coupe doesn’t offer an active sway bar system.

The X6 M60i xDrive offers an available adjustable active suspension system, which counteracts cornering forces actively, limiting body roll and improving handling and stability. Mercedes doesn’t offer an active suspension on the GLC Coupe.

The X6 has a standard driver-adjustable suspension system. It allows the driver to choose between an extra-supple ride, reducing fatigue on long trips, or a sport setting, which allows maximum control for tricky roads or off-road. The GLC Coupe’s suspension doesn’t offer adjustable shock absorbers.

The X6 has a standard automatic load leveling suspension to keep ride height level with a heavy load or when towing. The GLC Coupe doesn’t offer a load leveling suspension.

For a smoother ride and more stable handling, the X6’s wheelbase is 3.4 inches longer than on the GLC Coupe (117.1 inches vs. 113.7 inches).

For better handling and stability, the average track (width between the wheels) on the X6 is 2.4 inches wider in the front and 2.3 inches wider in the rear than the track on the GLC Coupe.

For greater off-road capability the X6 has a 3.4 inches greater minimum ground clearance than the GLC Coupe (8.5 vs. 5.1 inches), allowing the X6 to travel over rougher terrain without being stopped or damaged. The X6’s minimum ground clearance is .3 inch higher than on the GLC Coupe (8.5 vs. 8.2 inches).

The front grille of the X6 uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The GLC Coupe doesn’t offer active grille shutters.

The X6 has .4 inches more front headroom, 2.7 inches more front shoulder room and 1.9 inches more rear shoulder room than the GLC Coupe.

The X6 has a much larger cargo volume with its rear seat up than the GLC Coupe with its rear seat up (27.4 vs. 19.2 cubic feet). The X6 has a much larger cargo volume with its rear seat folded than the GLC Coupe with its rear seat folded (59.6 vs. 52.6 cubic feet).

Manual rear side window sunshades are available in the X6 to help block heat and glare for the rear passengers. The GLC Coupe doesn’t offer rear side window sunshades.

The X6 offers optional massaging front seats in order to maximize comfort and eliminate fatigue on long trips. Massaging seats aren’t available in the GLC Coupe.

The X6’s Parking Assistant Plus can parallel park or back into a parking spot by itself, with the driver only controlling the transmission and speed with the brake pedal. With its available fully controlled system, the driver just activates it and it parks autonomously, starting, stopping and changing direction automatically. Optional Remote Parking will park and retrieve your car remotely: press a button and watch it park itself. This is ideal for tight locations. The GLC Coupe’s automatic parking system does not offer parking by remote control.
