The GLC’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Allroad doesn’t offer a driver alert monitor.

Both the GLC and the Allroad have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, height-adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras, 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 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 Allroad 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 Allroad doesn’t offer drift compensation steering.

For a smoother ride and more stable handling, the GLC’s wheelbase is 2.2 inches longer than on the Allroad (113.1 inches vs. 110.9 inches).

The GLC is 3.7 inches shorter than the Allroad, making the GLC easier to handle, maneuver and park in tight spaces.

The GLC 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 Allroad doesn’t offer a remote starting system.

Unlike the driver-only memory seat and mirrors optional at extra cost in the Allroad, the GLC offers an optional passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position and outside mirror angle and the front passenger seat also adjusts to the new passenger’s preset preferences.

The GLC’s standard easy entry system raises the steering wheel, making it easier for the driver to get in and out. The Allroad doesn’t offer an easy entry system.

If the windows are left open on the GLC the driver can close them all at the outside door handle or from a distance using the remote. On a hot day the driver can lower the windows from a distance using the keyless remote. The driver of the Allroad can’t use the remote to operate the windows.

The Insurance Institute for Highway Safety (IIHS) conducts detailed tests on headlights for their range both straight ahead and in curves and to be certain they don’t exceed acceptable amounts of glare to oncoming drivers. The GLC’s available headlights were rated “Good” by the IIHS, while the Allroad’s headlights are rated “Marginal.”

The Allroad’s cornering lamps activate a lamp on the front corner when the turn signal is activated. The GLC’s optional adaptive cornering lights turn the actual headlight unit up to several degrees, depending on steering wheel angle and vehicle speed. This lights a significant distance into corners at any speed.

When the GLC is put in reverse, the passenger rearview mirror tilts from its original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirror into its original position. The Allroad’s mirror doesn’t automatically adjust for backing.

The GLC has a 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 Allroad doesn’t offer a house-current electrical outlet.

The GLC’s optional Active Parking Assist can parallel park or back into a parking spot by itself, starting and stopping automatically, with the driver only responsible for switching from reverse to drive. The Allroad doesn’t offer an automated parking system.
