Compare the2023 Mercedes GLCVS 2023 GMC Acadia

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 GMC Acadia doesn’t offer pretensioners for its second-row 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 Acadia doesn’t offer a whiplash protection system.

Over 200 people are killed each year when backed over by motor vehicles. The GLC 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.

Both the GLC and Acadia have rear cross-traffic warning, but the GLC has Active Brake Assist (automatically applies the brakes) to better prevent a collision when backing near traffic. The Acadia’s Rear Cross Traffic Alert doesn’t automatically brake.

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 Acadia doesn’t offer a driver alert monitor.

Both the GLC 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, available all wheel drive, lane departure warning systems and around view monitors.

The GLC comes with a full 4-year/50,000-mile basic warranty, which covers the entire truck and includes 24-hour roadside assistance. The Acadia’s 3-year/36,000-mile basic warranty expires 1 year or 14,000 miles sooner.

The GLC’s corrosion warranty is unlimited miles longer than the Acadia’s (unlimited vs. 100,000 miles).

The GLC’s 2.0 turbo 4-cylinder hybrid produces 27 more horsepower (255 vs. 228) and 37 lbs.-ft. more torque (295 vs. 258) than the Acadia’s standard 2.0 turbo 4-cylinder. The GLC’s 2.0 turbo 4-cylinder hybrid produces 24 lbs.-ft. more torque (295 vs. 271) than the Acadia’s optional 3.6 DOHC V6.

On the EPA test cycle the GLC gets better mileage than the Acadia:

The GLC 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.

For better stopping power the GLC’s brake rotors are larger than those on the Acadia:

The GLC stops much shorter than the Acadia:

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 Acadia SLE/SLT’s standard 65 series tires. The GLC’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 has standard 18-inch wheels. Smaller 17-inch wheels are standard on the Acadia AT4.

The GLC 300 4MATIC handles at .88 G’s, while the Acadia Denali AWD pulls only .85 G’s of cornering force in a Car and Driver skidpad test.

The GLC is 7.7 inches shorter than the Acadia, making the GLC easier to handle, maneuver and park in tight spaces.

The GLC has 1.3 inches more front headroom, 3.3 inches more front hip room, .1 inches more rear headroom and 5 inches more rear hip room than the Acadia.

The GLC has a much larger cargo volume than the Acadia with its rear seat up (21.9 vs. 12.8 cubic feet).

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

The GLC’s standard towing capacity is much higher than the Acadia’s (5291 vs. 1000 pounds).

Standard Trailer Stability Assist on the GLC uses the Electronic Stability Program sensors to detect trailer sway, then uses individual brakes to counteract any swaying and help keep the tow vehicle and trailer steady. The Acadia doesn’t offer electronic trailer sway control.

The engine in the GLC 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 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 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’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 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’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The Acadia’s intermittent wipers change speed with vehicle speed, but can’t turn on and off or change speed based on changing rainfall.

To help drivers see further while navigating curves, the GLC offers optional adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle. The Acadia doesn’t offer cornering lights.

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