Compare the2022 BMW X4VS 2021 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.

Over 200 people are killed each year when backed over by motor vehicles. The X4 offers optional Active Park Distance Control that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The GLC doesn’t offer backup collision prevention brakes.

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.

J.D. Power and Associates rated the X4 first among compact premium suvs in their 2021 Initial Quality Study. The GLC isn’t in the top three.

J.D. Power and Associates’ 2021 Initial Quality Study of new car owners surveyed provide the statistics that show that BMW vehicles are better in initial quality than Mercedes vehicles. J.D. Power ranks BMW 20th in initial quality. With 27 more problems per 100 vehicles, Mercedes is ranked 25th.

J.D. Power and Associates’ 2021 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 vehicles. J.D. Power ranks BMW 10th in reliability, above the industry average. With 14 more problems per 100 vehicles, Mercedes is ranked 15th.

From surveys of all its subscribers, Consumer Reports’ January 2021 Auto Issue reports that BMW vehicles are more reliable than Mercedes vehicles. Consumer Reports ranks BMW 8 places higher in reliability than Mercedes.

The X4 M40i’s standard 3.0 turbo 6-cylinder hybrid produces 127 more horsepower (382 vs. 255) and 96 lbs.-ft. more torque (369 vs. 273) than the GLC’s 2.0 turbo 4-cylinder.

Regenerative brakes improve the X4’s fuel efficiency by converting inertia back into energy instead of wasting it. The GLC doesn’t offer a regenerative braking system.

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

The X4 stops much 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 M40i’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 M40i’s optional 21-inch wheels are larger than the 20-inch wheels optional on the GLC.

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.

For better handling and stability, the average track (width between the wheels) on the X4 is 1.5 inches wider in the rear than the track on the GLC.

The X4’s front to rear weight distribution is more even (50.2% to 49.8%) than the GLC’s (53% to 47%). This gives the X4 more stable handling and braking.

The X4 M40i handles at .89 G’s, while the GLC 300 4MATIC pulls only .80 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).

For greater off-road capability the X4 has a 3 inches greater minimum ground clearance than the GLC (8 vs. 5 inches), allowing the X4 to travel over rougher terrain without being stopped or damaged.

The X4 has 1.7 inches more front headroom and .2 inches more front shoulder room than the GLC.

The X4 has a much larger cargo volume than the GLC with its rear seat up (23.7 vs. 19.4 cubic feet).
