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.

To help make backing safer, the Discovery’s cross-path warning system uses wide-angle radar in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The GLS doesn’t offer a cross-path warning system.

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, daytime running lights, rearview cameras, driver alert monitors, available crash mitigating brakes, blind spot warning systems and around view monitors.


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


The Discovery’s 3.0 turbo V6 diesel produces 74 lbs.-ft. more torque (443 vs. 369) than the GLS 450’s standard 3.0 turbo V6.

Suspension and Handling

For better handling and stability, the average track (width between the wheels) on the Discovery is 1.2 inches wider in the front and .3 inches wider in the rear than the average track on the GLS.

For greater off-road capability the Discovery has a greater minimum ground clearance than the AMG GLS 63 (8.7 vs. 7.8 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 850 pounds less than the Mercedes GLS.

The Discovery is 6.3 inches shorter than the GLS, making the Discovery easier to handle, maneuver and park in tight spaces.

The design of the Land Rover Discovery amounts to more than styling. The Discovery has an aerodynamic coefficient of drag of .36 Cd (optional .35 Cd with Td6). That is lower than the GLS (.37 to .38). A more efficient exterior helps keep the interior quieter and helps the Discovery get better fuel mileage.

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.

Passenger Space

The Discovery has 1.9 inches more front shoulder room and 1.1 inches more rear shoulder room than the GLS.

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.

Cargo Capacity

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


The Discovery’s standard towing capacity is much higher than the GLS’ (8201 vs. 7500 pounds).


The Discovery HSE/HSE Luxury offers an optional heads-up display that projects speed and navigation instruction readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The GLS doesn’t offer a heads-up display.

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.

Consumer Reports rated the Discovery’s headlight performance “Very Good,” a higher rating than the GLS’ headlights, which were rated “Good.”


Optional air conditioned the front and second row seats keep the Discovery’s passengers comfortable and take the sting out of hot leather in summer. The GLS doesn’t offer air-conditioned seats for the second row.

The Discovery has a standard dual zone air conditioning allows the driver and front passenger to choose two completely different temperatures so people with different temperature preferences won’t have to compromise. This makes both the driver and front passenger as comfortable as possible. Dual zone air conditioning costs extra on the GLS.
