Compare the2023 BMW X5 MVS 2023 Mercedes AMG GLS

The BMW X5 M 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 AMG GLS doesn’t offer a front passenger side knee airbag.

Over 200 people are killed each year when backed over by motor vehicles. The X5 M 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 AMG GLS doesn’t offer automatic braking for stationary objects directly to the rear.

Both the X5 M and the AMG GLS 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, all wheel drive, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, post-collision automatic braking systems, daytime running lights, lane departure warning systems, blind spot warning systems, around view monitors, rear cross-path warning and driver alert monitors.

For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard vehicle-to-vehicle front crash prevention system, its standard vehicle-to-pedestrian front crash prevention system, and its available headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the X5 M the rating of “Top Safety Pick” for 2022, a rating granted to only 176 vehicles tested by the IIHS.

The X5 M Competition’s standard 4.4 turbo V8 produces 14 more horsepower (617 vs. 603) than the AMG GLS’ 4.0 turbo V8 hybrid.

The X5 M’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 AMG GLS doesn’t offer launch control.

For better traction, the X5 M has larger front tires than the AMG GLS (F:295/35R21 & R:315/30R21 vs. F:275/50R21 & R:315/45R21). The X5 M’s front tires are larger than the largest tires available on the AMG GLS (295/35R21 vs. 285/45R22).

The X5 M’s 295/35R21 front and 315/30R21 rear tires provide better handling because they have a lower 35 series front and 30 series rear profile (height to width ratio) that provides a stiffer sidewall than the AMG GLS 63’s standard 50 series front and 45 series rear tires. The X5 M’s tires are lower profile than the AMG GLS’ optional 40 series front and 35 series rear tires.

The X5 M has active sway bars, which help keep it flat and controlled during cornering, but disconnect at lower speeds to smooth the ride and offer greater off-road suspension articulation.
