Compare the2024 BMW X1VS 2024 Mercedes GLB

The BMW X1 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 GLB doesn’t offer a front passenger side knee airbag.

The X1 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 GLB 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 X1 has a standard Active Park Distance Control that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The GLB doesn’t offer automatic braking for stationary objects directly to the rear.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the X1. But it costs extra on the GLB.

The X1’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 GLB.

Both the X1 and the GLB 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 BMW X1 achieved a “Top Safety Pick” rating from the Insurance Institute for Highway Safety (IIHS) for the 2024 model year. This recognition was based on its impressive performance in the small overlap frontal crash test, updated side impact crash test, headlight evaluations, and pedestrian crash prevention testing. The GLB has not yet been evaluated by the IIHS for 2024.

The X1’s corrosion warranty is 7 years longer than the GLB’s (12 vs. 5 years).

BMW pays for scheduled maintenance on the X1 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 GLB.

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 X1’s reliability 32 points higher than the GLB.

J.D. Power and Associates’ 2023 Initial Quality Study of new car owners surveyed provide the statistics that show that BMW vehicles are better in initial quality than Mercedes vehicles. With 9 fewer problems per 100 vehicles, JD Power ranks BMW higher than Mercedes.

J.D. Power and Associates’ 2022 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 above average in long-term dependability. With 5 more problems per 100 vehicles in the first three years of ownership, Mercedes is rated below average.

From surveys of all its subscribers, Consumer Reports’ January 2024 Auto Issue reports that BMW vehicles are more reliable than Mercedes vehicles. Consumer Reports ranks BMW 20 places higher in reliability than Mercedes.

The X1 xDrive28i’s standard 2.0 turbo 4-cylinder produces 20 more horsepower (241 vs. 221) and 37 lbs.-ft. more torque (295 vs. 258) than the GLB’s 2.0 turbo 4-cylinder hybrid. The X1 M35i xDrive’s standard 2.0 turbo 4-cylinder produces 92 more horsepower (313 vs. 221) and 37 lbs.-ft. more torque (295 vs. 258) than the GLB’s 2.0 turbo 4-cylinder hybrid.

As tested in Motor Trend the X1 xDrive28i is faster than the Mercedes GLB:

On the EPA test cycle the X1 gets better mileage than the GLB:

The X1’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 GLB doesn’t offer launch control.

For better stopping power the X1’s front brake rotors are larger than those on the GLB:

The X1’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs on the GLB are solid, not vented.

The X1 stops shorter than the GLB:

For better traction, the X1’s optional tires are larger than the largest tires available on the GLB (245/45R19 vs. 235/55R18).

The X1’s optional tires provide better handling because they have a lower 40 series profile (height to width ratio) that provides a stiffer sidewall than the GLB’s optional 45 series tires.

The X1 has a standard space-saver spare tire so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the GLB; it requires you to depend on its run-flat tires, which limits mileage and speed before they are repaired. If a run-flat is damaged beyond repair by a road hazard your vehicle will have to be towed. Some tire options on the GLB don’t have a run-flat feature, either.

The X1 xDrive28i handles at .85 G’s, while the GLB 250 4MATIC pulls only .82 G’s of cornering force in a Motor Trend skidpad test.

The X1 xDrive28i executes Motor Trend’s “Figure Eight” maneuver 1.2 seconds quicker than the GLB 250 4MATIC (26.3 seconds @ .67 average G’s vs. 27.5 seconds @ .63 average G’s).

For greater off-road capability the X1 has a greater minimum ground clearance than the GLB (8.1 vs. 7.9 inches), allowing the X1 to travel over rougher terrain without being stopped or damaged.

The X1 xDrive28i is 5.2 inches shorter than the GLB, making the X1 easier to handle, maneuver and park in tight spaces.

The design of the BMW X1 amounts to more than styling. The X1 has an aerodynamic coefficient of drag of .27 Cd. That is significantly lower than the GLB (.32) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the X1 get better fuel mileage.

The front grille of the X1 uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The GLB doesn’t offer active grille shutters.

The X1 has 1.4 inches more front headroom, .2 inches more front shoulder room and .2 inches more rear shoulder room than the GLB.

The X1 has a much larger cargo volume than the GLB with its rear seat up (25.7 vs. 5.1 cubic feet).

The X1 has a 3500 lbs. towing capacity. The GLB has no towing capacity.

Standard Trailer Stabilization Control on the X1 uses the Dynamic Stability Control sensors to detect trailer sway, then uses individual brakes to counteract any swaying and help keep the tow vehicle and trailer steady. The GLB doesn’t offer electronic trailer sway control.

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.

Heated windshield washer nozzles are standard on the X1 to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. Heated windshield washer nozzles cost extra on the GLB.

Consumer Reports rated the X1’s headlight performance “Good,” a higher rating than the GLB’s headlights, which were rated “Fair.”

Insurance will cost less for the X1 owner. The Complete Car Cost Guide estimates that insurance for the X1 will cost $490 to $785 less than the GLB over a five-year period.

Consumer Reports® recommends the BMW X1, based on reliability, safety and performance. The Mercedes GLB isn't recommended.

J.D. Power and Associates rated the X1 third among small premium suvs in owner reported satisfaction. This includes how well the vehicle performs and satisfies its owner’s expectations. The GLB isn’t in the top three.

The BMW X1 outsold the Mercedes GLB by 26% during 2023.
