Safety Comparison

Both the Range Rover and GLS have child safety locks to prevent children from opening the rear doors. The Range Rover 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 Range Rover’s optional 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 Range Rover and the GLS have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front and rear seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, all wheel drive, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras, available blind spot warning systems, around view monitors and driver alert monitors.

Consumer Reports

Suspension and Handling Comparison

For better handling and stability, the track (width between the wheels) on the Range Rover is 1.1 inches wider in the front and .1 inches wider in the rear than the average track on the GLS.

The Range Rover SVAutobiography handles at .78 G’s, while the GLS450 pulls only .74 G’s of cornering force in a Car and Driver skidpad test.

The Range Rover Supercharged executes Motor Trend’s “Figure Eight” maneuver 2 seconds quicker than the GLS350d (26.7 seconds @ .71 average G’s vs. 28.7 seconds @ .54 average G’s).

For greater off-road capability the Range Rover has a greater minimum ground clearance than the GLS (11.6 vs. 10.9 inches), allowing the Range Rover to travel over rougher terrain without being stopped or damaged.

Chassis Comparison

The Land Rover Range Rover may be more efficient, handle and accelerate better because it weighs about 200 to 550 pounds less than the Mercedes GLS.

The Range Rover is 5.2 inches shorter than the GLS, making the Range Rover easier to handle, maneuver and park in tight spaces.

The design of the Land Rover Range Rover amounts to more than styling. The Range Rover offers aerodynamic coefficients of drag from .35 to .36 Cd (depending on bodystyle and options). That is lower than the GLS (.369 to .38). A more efficient exterior helps keep the interior quieter and helps the Range Rover get better fuel mileage.

The front grille of the Range Rover Diesel 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.

As tested by Car and Driver while under full throttle, the interior of the Range Rover SVAutobiography is quieter than the GLS450 (70 vs. 71 dB).

Passenger Space Comparison

The Range Rover SVAutobiography Long Wheelbase offers an optional rear tailgate seat that can be flipped rearward and used for tailgate picnics. (Do not use seat reversed while vehicle in motion.) The GLS doesn’t offer a rear tailgate seat.

Cargo Capacity Comparison

The Range Rover SVAutobiography’s optional sliding cargo floor makes loading and unloading cargo easier and safer. The GLS doesn’t offer a sliding load floor.

The Range Rover’s rear cargo window opens separately from the rest of the tailgate door to allow quicker loading of small packages. The GLS’ rear cargo window doesn’t open.

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

Ergonomics Comparison

The Range Rover has a standard remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The GLS doesn’t offer a remote starting system.

The Range Rover’s standard easy entry system raises the steering wheel and glides the driver’s seat back, making it easier for the driver to get in and out. An easy entry system costs extra on the GLS.

The Range Rover offers an optional heads-up display which 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 Range Rover has a standard rear speed-sensitive 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.

The Range Rover HSE/Supercharged/Autobiography has standard front air conditioned seats and offers them optionally in the rear. This keeps the passengers comfortable and takes the sting out of hot seats in Summer. The GLS doesn’t offer air conditioned seats for the second row.

The Range Rover has a standard heated steering wheel to take the chill out of steering on extremely cold Winter days before the vehicle heater warms up. A heated steering wheel costs extra on the GLS.

Economic Advantages Comparison

According to The Car Book by Jack Gillis, the Range Rover is less expensive to operate than the GLS because it costs $225 less to do the manufacturer’s suggested maintenance for 50,000 miles. Typical repairs cost much less on the Range Rover than the GLS, including $488 less for a water pump, $354 less for an alternator, $78 less for front brake pads, $95 less for a starter and $1095 less for a power steering pump.

Recommendations Comparison

J.D. Power and Associates rated the Range Rover first among large premium SUVs in owner reported satisfaction. This includes how well the vehicle performs and satisfies its owner’s expectations. The GLS was rated third.
