Safety Comparison

For enhanced safety, the front and rear seat shoulder belts of the Mercedes GLC have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Land Rover Discovery Sport doesn’t offer pretensioners for the rear seat belts.

The GLC’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Discovery Sport doesn’t offer pre-crash pretensioners.

For enhanced safety, the front seat shoulder belts of the Mercedes GLC 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 Land Rover Discovery Sport doesn’t offer height-adjustable seat belts.

The GLC has standard NECK-PRO front head restraints, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the NECK-PRO front head restraints system moves the headrests forward to prevent neck and spine injuries. The Discovery Sport doesn’t offer a whiplash protection system.

Both the GLC and the Discovery Sport have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available all-wheel drive, lane departure warning systems, blind spot warning systems and around view monitors.

Warranty Comparison

There are over 2 times as many Mercedes dealers as there are Land Rover dealers, which makes it much easier should you ever need service under the GLC’s warranty.

The GLC300’s standard 2.0 turbo 4 cyl. produces 1 more horsepower (241 vs. 240) and 23 lbs.-ft. more torque (273 vs. 250) than the Discovery Sport’s 2.0 turbo 4 cyl. The AMG GLC43’s standard 3.0 turbo V6 produces 122 more horsepower (362 vs. 240) and 134 lbs.-ft. more torque (384 vs. 250) than the Discovery Sport’s 2.0 turbo 4 cyl.

Tires and Wheels Comparison

For better traction, the AMG GLC43’s tires are larger than the largest tires available on the Discovery Sport (F:255/45R20 & R:285/40R20 vs. 245/45R20).

The AMG GLC43’s 285/40R20 rear tires provide better handling because they have a lower 40 series profile (height to width ratio) that provides a stiffer sidewall than the Discovery Sport HSE/HSE LUX’s optional 45 series tires.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires available on the GLC can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The Discovery Sport doesn’t offer run-flat tires.

Suspension and Handling Comparison

The GLC has standard front and rear gas-charged shocks for better control over choppy roads. The Discovery Sport’s suspension doesn’t offer rear gas-charged shocks.

The GLC has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The GLC’s 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 Discovery Sport doesn’t offer a load leveling suspension.

The GLC’s 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 Discovery Sport doesn’t offer drift compensation steering.

For a smoother ride and more stable handling, the GLC’s wheelbase is 5.2 inches longer than on the Discovery Sport (113.1 inches vs. 107.9 inches).

The GLC300 4MATIC handles at .83 G’s, while the Discovery Sport HSE pulls only .82 G’s of cornering force in a Motor Trend skidpad test.

The GLC300 4MATIC executes Motor Trend’s “Figure Eight” maneuver quicker than the Discovery Sport HSE (26.6 seconds @ .66 average G’s vs. 27.4 seconds @ .64 average G’s).

Chassis Comparison

The GLC is 6.2 inches narrower on average than the Discovery Sport, making the GLC easier to handle and maneuver in traffic.

The design of the Mercedes GLC amounts to more than styling. The GLC has an aerodynamic coefficient of drag of .31 Cd. That is significantly lower than the Discovery Sport (.36) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the GLC get better fuel mileage.

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

Cargo Capacity Comparison

The GLC has a much larger cargo area than the Discovery Sport with its rear seat up (19.4 vs. 6.8 cubic feet).

A standard locking glovebox (which can’t be accessed with the valet key) keeps your small valuables safer in the GLC. The Discovery Sport doesn’t offer locking storage for small valuables.

Ergonomics Comparison

If the windows are left down on the GLC the driver can raise them all using the key in the outside lock cylinder or the keyless remote; on a hot day the driver can lower the windows. The driver of the Discovery Sport can only raise the windows from inside the vehicle, with the ignition on.

Heated windshield washer nozzles are optional on the GLC to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The Discovery Sport doesn’t offer heated windshield washer nozzles.

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the GLC has standard extendable sun visors. The Discovery Sport doesn’t offer extendable visors.

The GLC has standard automatic dimming rear and side view mirrors which automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The Discovery Sport offers an automatic rear view mirror, but its side mirrors don’t dim.

To keep a safe, consistent following distance, the GLC offers an optional Distronic Plus, which alters the speed of the vehicle without driver intervention. This allows the driver to use cruise control more safely without constantly having to disengage it when approaching slower traffic. The Discovery Sport doesn’t offer an adaptive cruise control.

The GLC offers an optional 115-volt a/c outlet on the center console, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The Discovery Sport doesn’t offer a house-current electrical outlet.

Recommendations Comparison

J.D. Power and Associates rated the GLC third among compact premium suvs in owner reported satisfaction. This includes how well the vehicle performs and satisfies its owner’s expectations. The Discovery Sport isn’t in the top three.

Motor Trend selected the GLC as their 2017 Sport Utility of the Year. The Discovery Sport has never been chosen.

The Mercedes GLK/GLC outsold the Land Rover Discovery Sport by over three to one during the 2016 model year.
