Compare the2025 BMW X4VS 2025 Mercedes GLC

The BMW X4 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 doesn’t offer a front passenger side knee airbag.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the X4. But it costs extra on the GLC.

The X4’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.

Both the X4 and the GLC 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, 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 X4’s corrosion warranty is 7 years longer than the GLC’s (12 vs. 5 years).

BMW pays for scheduled maintenance on the X4 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.

A reliable vehicle saves its owner time, money and trouble. Nobody wants to be stranded or have to be without a vehicle while it’s being repaired. Consumer Reports rates the X4’s reliability 24 points higher than the GLC.

J.D. Power and Associates rated the X4 first among compact premium suvs in their 2024 Initial Quality Study. The GLC isn’t in the top three in its category.

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 X4 M40i’s standard 3.0 turbo 6-cylinder hybrid produces 69 more horsepower (382 vs. 313) than the GLC 350e’s standard 2.0 turbo 4-cylinder hybrid.

The X4 has 4.3 gallons more fuel capacity than the GLC 350e’s standard fuel tank (17.2 vs. 12.9 gallons), for longer range between fill-ups.

For better stopping power the X4 M40i’s brake rotors are larger than those on the GLC:

The X4 stops shorter than the GLC:

For better traction, the X4 has larger standard tires than the GLC (245/50R19 vs. 235/60R18).

The X4’s standard tires provide better handling because they have a lower 50 series profile (height to width ratio) that provides a stiffer sidewall than the GLC’s standard 60 series tires. The X4’s optional 245/40R21 front and 275/35R21 rear tires have a lower 40 series front and 35 series rear profile than the GLC’s optional 45 series tires.

For better ride, handling and brake cooling the X4 has standard 19-inch wheels. Smaller 18-inch wheels are standard on the GLC. The X4’s optional 21-inch wheels are larger than the 20-inch wheels optional on the GLC.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the X4 can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The GLC doesn’t offer run-flat tires.

The X4 offers an optional 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’s suspension doesn’t offer adjustable shock absorbers.

The X4 M40i handles at .89 G’s, while the GLC 300 4MATIC pulls only .87 G’s of cornering force in a Motor Trend skidpad test.

The X4 M40i executes Motor Trend’s “Figure Eight” maneuver 1.7 seconds quicker than the GLC 300 4MATIC (25.6 seconds @ .73 average G’s vs. 27.3 seconds @ .65 average G’s).

The front grille of the X4 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 doesn’t offer active grille shutters.

J.D. Power and Associates rated the X4 first among compact premium suvs in owner reported satisfaction. This includes how well the vehicle performs and satisfies its owner’s expectations. The GLC isn’t in the top three.
