Compare the2025 Mercedes AMG GLBVS 2025 BMW X4 M

For enhanced safety, the front and second-row seat shoulder belts of the Mercedes AMG GLB have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The BMW X4 M doesn’t offer pretensioners for its rear seat belts.

For enhanced safety, the front seat shoulder belts of the Mercedes AMG GLB are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The BMW X4 M doesn’t offer height-adjustable seat belts.

Both the AMG GLB and X4 M have rear cross-traffic warning, but the AMG GLB has Active Brake Assist (automatically applies the brakes) to better prevent a collision when backing near traffic. The X4 M’s Cross Traffic Warning doesn’t automatically brake.

Both the AMG GLB and the X4 M have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, four-wheel antilock brakes, all wheel drive, 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 lane departure warning systems.

There are over 10 percent more Mercedes dealers than there are BMW dealers, which makes it easier should you ever need service under the AMG GLB’s warranty.

On the EPA test cycle the AMG GLB gets better mileage than the X4 M:

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Mercedes AMG GLB higher (5 out of 10) than the BMW X4 M (2). This means the AMG GLB produces up to 20.8 pounds less smog-producing pollutants than the X4 M every 15,000 miles.

The AMG GLB offers a standard sequential manual gearbox (SMG). With no clutch pedal to worry about and a fully automatic mode, an SMG is much more efficient than a conventional automatic but just as easy to drive. The X4 M doesn’t offer an SMG or a conventional manual transmission.

The AMG GLB’s optional tires provide better handling because they have a lower 35 series profile (height to width ratio) that provides a stiffer sidewall than the X4 M Competition’s 40 series tires.

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

The AMG GLB’s drift compensation steering can automatically compensate for road conditions which would cause the vehicle to drift from side to side, helping the driver to keep the vehicle straight more easily. The X4 M doesn’t offer drift compensation steering.

The Mercedes AMG GLB may be more efficient, handle and accelerate better because it weighs about 750 pounds less than the BMW X4 M.

The AMG GLB is 4.4 inches shorter than the X4 M, making the AMG GLB easier to handle, maneuver and park in tight spaces.

The AMG GLB offers optional seating for 7 passengers; the X4 M can only carry 5.

The AMG GLB has 1.2 inches more front headroom, .4 inches more front legroom, 2.1 inches more rear headroom and 2.6 inches more rear legroom than the X4 M.

The AMG GLB’s cargo area provides more volume than the X4 M.

Unlike the driver-only memory system in the X4 M, the AMG GLB has standard driver and passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, suspension setting, power steering assist, outside mirror angle, climate settings and radio stations and the front passenger seat also adjusts to the new passenger’s preset preferences.

The AMG GLB’s standard easy entry and exit feature glides the driver’s seat back, making it easier for the driver to get in and out. The X4 M doesn’t offer an easy entry system.

The AMG GLB’s standard Keyless-Go allow you to unlock the doors from any outside door handle, open the cargo door, and start the engine, all without removing the key from the pocket or purse. Comfort Access standard on the X4 M doesn’t offer a sensor on the rear doors, so you’ll have to reach a front handle to unlock the rear door.

To improve rear visibility by keeping the rear window clear, the AMG GLB has a standard rear wiper. The X4 M doesn’t offer a rear wiper.

The AMG GLB offers optional massaging front seats in order to maximize comfort and eliminate fatigue on long trips. Massaging seats aren’t available in the X4 M.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Mercedes AMG GLB has a standard wireless phone charging system (Qi) in the center console. Wireless charging costs extra on the X4 M.

The AMG GLB has a 115-volt a/c outlet on the center console, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The X4 M doesn’t offer a house-current electrical outlet.
