Compare the2024 Mercedes GLBVS 2024 BMW X3

For enhanced safety, the front and second-row seat shoulder belts of the Mercedes 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 doesn’t offer pretensioners for its rear seat belts.

For enhanced safety, the front seat shoulder belts of the Mercedes 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 doesn’t offer height-adjustable seat belts.

Both the GLB and X3 have rear cross-traffic warning, but the GLB has Active Brake Assist (automatically applies the brakes) to better prevent a collision when backing near traffic. The X3’s Cross Traffic Warning doesn’t automatically brake.

Both the GLB and the X3 have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, 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, available all wheel drive, lane departure warning systems and around view monitors.

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

As tested in Motor Trend the Mercedes GLB is faster than the X3 s/xDrive30i 2.0 turbo 4-cylinder:

On the EPA test cycle the GLB gets better mileage than the X3:

The 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 doesn’t offer an SMG or a conventional manual transmission.

The 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 doesn’t offer drift compensation steering.

The GLB 250 4MATIC handles at .83 G’s, while the X3 xDrive30i pulls only .81 G’s of cornering force in a Motor Trend skidpad test.

For better maneuverability, the GLB’s turning circle is 1 foot tighter than the X3’s (38.4 feet vs. 39.4 feet).

The Mercedes GLB may be more efficient, handle and accelerate better because it weighs about 450 to 500 pounds less than the BMW X3.

The GLB is 3.5 inches shorter than the X3, making the GLB easier to handle, maneuver and park in tight spaces.

The design of the Mercedes GLB amounts to more than styling. The GLB has an aerodynamic coefficient of drag of .32 Cd. That is lower than the X3 (.32 to .35) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the GLB get better fuel mileage.

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

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

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

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

The 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 Go standard on the X3 only offers hands-free access for the ignition, none to unlock the vehicle.

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

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Mercedes GLB has a standard wireless phone charging system (Qi) in the center console. Wireless charging costs extra on the X3.

The GLB offers an optional 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 doesn’t offer a house-current electrical outlet.

The GLB will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the GLB will retain 61.32% of its original price after five years, while the X3 only retains 50.69% to 52.37%.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Mercedes GLB will be $9743 to $21979 less than for the BMW X3.
