Compare the2025 Mercedes AMG GLSVS 2024 BMW XM

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

Earlier warning of stopped traffic, traffic signals, dangerous road conditions, weather, or accidents, can keep driver's safer and prevent crashes. The AMG GLS has Car-to-X Communication, a system that seamlessly communicates important warnings to the driver about impending danger, if they're available. The XM doesn’t offer a system that can receive automated systems from infrastructure or other vehicles.

Both the AMG GLS and the XM 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.

An engine control system that can shut down some of the engine’s cylinders helps improve the AMG GLS’ fuel efficiency. The XM doesn’t offer a system that can shut down part of the engine.

The front and rear suspension of the AMG GLS uses air springs for a smoother, controlled ride than the XM, which uses coil springs in front. Air springs maintain proper ride height and ride more smoothly.

The AMG GLS has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The AMG GLS’ height leveling suspension allows the driver to raise ride height for better off-road clearance and then lower it again for easier entering and exiting and better on-road handling. The XM doesn’t offer a load leveling suspension.

The AMG GLS’ 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 XM doesn’t offer drift compensation steering.

To make loading groceries and cargo easier when your hands are full, the AMG GLS’ liftgate can be opened and closed just by kicking your foot under the back bumper, leaving your hands completely free. The XM doesn’t offer a hands-free gesture to open its liftgate, forcing you to put cargo down if your hands are full.

The AMG GLS’ 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.
