Compare the2025 Mercedes AMG GLBVS 2024 BMW X3 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 X3 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 X3 M doesn’t offer height-adjustable seat belts.

Both the AMG GLB and X3 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 X3 M’s Cross Traffic Warning doesn’t automatically brake.

Both the AMG GLB and the X3 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 X3 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 X3 M (3). This means the AMG GLB produces up to 16.5 pounds less smog-producing pollutants than the X3 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 X3 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 X3 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 X3 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 X3 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 X3 M.

The AMG GLB offers optional seating for 7 passengers; the X3 M can only carry 5.

The AMG GLB has .8 inches more front legroom, .8 inches more rear headroom and 1.7 inches more rear legroom than the X3 M.

The front step up height for the AMG GLB is 1.5 inches lower than the X3 M (17” vs. 18.5”). The AMG GLB’s rear step up height is 1 inches lower than the X3 M’s (17.5” vs. 18.5”).

Unlike the driver-only memory system in the X3 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 X3 M doesn’t offer an easy entry system.

Heated windshield washer nozzles are optional on the AMG GLB to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The X3 M doesn’t offer heated windshield washer nozzles.

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 X3 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 X3 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 X3 M doesn’t offer a house-current electrical outlet.

Insurance will cost less for the AMG GLB owner. The Complete Car Cost Guide estimates that insurance for the AMG GLB will cost $325 less than the X3 M over a five-year period.

The AMG GLB will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the AMG GLB will retain 54.15% of its original price after five years, while the X3 M only retains 54.06%.
