Compare the2022 Land Rover DiscoveryVS 2021 Mercedes GLS

Both the Discovery and GLS have child safety locks to prevent children from opening the rear doors. The Discovery has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The GLS’ child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.

The Discovery’s standard lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. A lane departure warning system costs extra on the GLS.

Both the Discovery and the GLS have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front and rear seatbelt pretensioners, 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, around view monitors, rear cross-path warning and driver alert monitors.

The Discovery’s corrosion warranty is 1 year longer than the GLS’ (6 vs. 5 years).

A reliable vehicle saves its owner time, money and trouble. Nobody wants to be stranded or have to be without a vehicle while it’s being repaired. Consumer Reports rates the Discovery’s reliability 17 points higher than the GLS.

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Land Rover Discovery higher (7 out of 10) than the Mercedes GLS (3 to 6). This means the Discovery produces up to 24.5 pounds less smog-producing pollutants than the GLS every 15,000 miles.

For better stopping power the Discovery P360’s brake rotors are larger than those on the GLS:

The Discovery offers an optional full size spare tire so a flat doesn’t interrupt your trip. A full size spare isn’t available on the GLS; it requires you to depend on a temporary spare, which has mileage and speed limitations, or roadside assistance and a tow-truck.

For greater off-road capability the Discovery has a greater minimum ground clearance than the GLS (11.1 vs. 10.1 inches), allowing the Discovery to travel over rougher terrain without being stopped or damaged.

The Land Rover Discovery may be more efficient, handle and accelerate better because it weighs about 600 to 950 pounds less than the Mercedes GLS.

The Discovery is 9.8 inches shorter than the GLS 450, making the Discovery easier to handle, maneuver and park in tight spaces.

The front grille of the Discovery uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The GLS doesn’t offer active grille shutters.

Flexibility is maximized at the game, campground or a drive-in theatre in the Discovery when its optional tailgating rear seats are deployed, allowing people to sit facing out of the liftgate. (Do not use while vehicle is in motion.) The GLS doesn’t offer tailgating seats.

The Discovery’s cargo area provides more volume than the GLS.

Maximum trailer towing in the Mercedes GLS is limited to 7716 pounds. The Discovery offers up to a 8200 lbs. towing capacity.

To improve rear visibility by keeping the rear window clear, the Discovery has a standard rear fixed intermittent wiper with a full on position. The rear wiper standard on the GLS only has an intermittent setting, so in a hard rain visibility isn’t as good.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The Discovery offers available headlight washers to keep headlight output high. The GLS doesn’t offer headlight washers.
