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 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 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 doesn’t offer a whiplash protection system.

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

For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard front crash prevention system, and its headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the GLC its highest rating: “Top Pick Plus” for 2019, a rating granted to only 55 vehicles tested by the IIHS. The Discovery has not been tested, yet.

The GLC’s standard tires provide better handling because they have a lower 60 series profile (height to width ratio) that provides a stiffer sidewall than the Discovery’s standard 65 series tires.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard 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 doesn’t offer run-flat tires.

The GLC offers an available driver-adjustable suspension system.

The Discovery’s suspension doesn’t offer adjustable shock absorbers.

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 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 doesn’t offer drift compensation steering.

The GLC 300 4MATIC handles at .83 G’s, while the Discovery HSE Luxury pulls only .69 G’s of cornering force in a Motor Trend skidpad test.

The GLC 300 4MATIC executes Motor Trend’s “Figure Eight” maneuver 2.6 seconds quicker than the Discovery HSE (26.6 seconds @ .66 average G’s vs. 29.2 seconds @ .57 average G’s).

For better maneuverability, the GLC’s turning circle is 1.9 feet tighter than the Discovery’s (38.7 feet vs. 40.6 feet).
