For enhanced safety, the front and middle seat shoulder belts of the Mercedes GLB have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision. The BMW X5 doesn’t offer pretensioners for the middle 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 X5 doesn’t offer height-adjustable seat belts.

Both the GLB and the X5 have standard driver and passenger frontal airbags, front and rear 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, rearview cameras, driver alert monitors, available all-wheel drive, lane departure warning systems, blind spot warning systems and around view monitors.

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 X5 doesn’t offer an SMG or a conventional manual transmission.

For better maneuverability, the GLB’s turning circle is 3 feet tighter than the X5’s (38.4 feet vs. 41.4 feet).

The Mercedes GLB may be more efficient, handle and accelerate better because it weighs about 1100 to 1300 pounds less than the BMW X5.

The GLB is 11.9 inches shorter than the X5, making the GLB easier to handle, maneuver and park in tight spaces.

The GLB is 6.7 inches narrower than the X5, making the GLB easier to handle and maneuver in traffic.

The design of the Mercedes GLB amounts to more than styling. The GLB has an aerodynamic coefficient of drag of .32 Cd. That is significantly lower than the X5 (.36 to .38) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the GLB get better fuel mileage.

The GLB’s liftgate lifts up in one piece, completely out of the way of loading and unloading, while sheltering the cargo loading area. The X5’s tailgate’s top part raises up, but the bottom part lowers, getting in the way of loading and making an uneven surface for sliding cargo.
