Compare the2023 Mercedes GLC Coupe VS 2023 GMC Acadia

For enhanced safety, the front and rear seat shoulder belts of the Mercedes GLC Coupe 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 GMC Acadia doesn’t offer pretensioners for its second-row seat belts.

The GLC Coupe 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 Acadia doesn’t offer a whiplash protection system.

The GLC Coupe offers an optional Post Collision Brake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Acadia doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

Over 200 people are killed each year when backed over by motor vehicles. The GLC Coupe has a standard Maneuvering Brake Function that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Acadia doesn’t offer backup collision prevention brakes.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the GLC Coupe. But it costs extra on the Acadia.

The GLC Coupe’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 Acadia doesn’t offer a driver alert monitor.

Both the GLC Coupe and the Acadia have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, blind spot warning systems, rearview cameras, rear cross-path warning and available lane departure warning systems.

On the EPA test cycle the GLC 300 Coupe gets better fuel mileage than the Acadia 3.6 DOHC V6 AWD (20 city/26 hwy vs. 19 city/26 hwy).

The GLC Coupe has a standard locking fuel door which locks and unlocks with the power locks The fuel filler door is not lockable on the Acadia. A locking fuel door helps prevent fuel theft and vandalism, such as sugar in the tank.

	GLC Coupe	Acadia
Front Rotors	13.5 inches	12.6 inches
Rear Rotors	12.6 inches	12.4 inches

The GLC Coupe’s standard tires provide better handling because they have a lower 55 series profile (height to width ratio) that provides a stiffer sidewall than the Acadia SLE/SLT’s standard 65 series tires. The GLC Coupe’s optional 255/45R20 front and 285/40R20 rear tires have a lower 45 series front and 40 series rear profile than the Acadia’s optional 55 series tires.

For better ride, handling and brake cooling the GLC Coupe has standard 19-inch wheels. Smaller 17-inch wheels are standard on the Acadia AT4.

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

The GLC Coupe’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 Acadia doesn’t offer drift compensation steering.

The engine in the GLC Coupe is mounted longitudinally (North-South), instead of sideways, as in the Acadia. This makes it easier to service and maintain, because there are no rear spark plugs and the accessory belts are in front.

Unlike the driver-only memory seat and mirrors in the Acadia (except SLE), the GLC Coupe 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 Coupe’s standard easy entry and exit feature 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 Acadia, and is not available on all models.

The GLC Coupe’s front and rear power windows all open or close fully with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside the car. The Acadia’s rear power window switches have to be held the entire time to open them fully. Only its driver’s window closes automatically.

If the windows are left open on the GLC Coupe 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 Acadia can only operate the windows from inside the vehicle, with the ignition on.

The GLC Coupe’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield.

The GLC Coupe also offers optional adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle.

The GLC Coupe’s 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 Acadia doesn’t offer an automated parking system.
