Compare the2023 BMW X4VS 2023 Mercedes GLC

The BMW X4 has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps 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.

The X4 has a standard PostCrash iBrake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The GLC doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

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

When descending a steep, off-road slope, the X4’s standard Hill Descent Control allows you to creep down safely. The GLC doesn’t offer Hill Descent Control.

The X4’s standard lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave 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, 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, lubrication and any other required maintenance. Mercedes doesn’t pay scheduled maintenance for the GLC.

The X4 M40i’s standard 3.0 turbo 6-cylinder hybrid produces 127 more horsepower (382 vs. 255) and 74 lbs.-ft. more torque (369 vs. 295) than the GLC’s 2.0 turbo 4-cylinder hybrid.

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 front and 40 series rear 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 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 surveys of service recipients show that BMW service is better than Mercedes. J.D. Power ranks BMW 7th in service department satisfaction (above the industry average). With a 17% lower rating, Mercedes is ranked 18th.

The X4 offers a remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The GLC doesn’t offer a remote starting system.
