For enhanced safety, the GMC Acadia’s middle seat shoulder belts have child comfort guides to move the belt to properly fit children. A better fit can prevent injuries and the increased comfort also encourages children to buckle up. The Mercedes GLC doesn’t offer comfort guides on its middle seat belts.

In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the Acadia are reminded to check the back seat if they opened the rear door before starting out. The GLC doesn’t offer a back seat reminder.

The Acadia has a standard front seat center airbag, which deploys between the driver and front passenger, protecting them from injuries caused by striking each other in serious side impacts. The GLC doesn’t offer front seat center airbags.

When descending a steep, off-road slope, the Acadia SLE/SLT’s optional Hill Descent Control allows you to creep down safely. The GLC doesn’t offer Hill Descent Control.

To help make backing safer, the Acadia (except SL)’s optional cross-path warning system uses wide-angle radar in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The GLC doesn’t offer a cross-path warning system.

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

GMC’s powertrain warranty covers the Acadia 1 year and 10,000 miles longer than Mercedes covers the GLC. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 5 years or 60,000 miles. Coverage on the GLC ends after only 4 years or 50,000 miles.

The Acadia’s corrosion warranty is 1 year longer than the GLC’s (6 vs. 5 years).

GMC pays for the first scheduled maintenance on the Acadia. GMC will pay for the first oil change, lubrication and any other required maintenance in the first year. Mercedes doesn’t pay scheduled maintenance for the GLC.

There are almost 5 times as many GMC dealers as there are Mercedes dealers, which makes it much easier should you ever need service under the Acadia’s warranty.


The Acadia’s optional 3.6 DOHC V6 produces 69 more horsepower (310 vs. 241) than the GLC 300’s standard 2.0 turbo 4 cyl.

As tested in Motor Trend the GMC Acadia V6 is faster than the GLC 300 2.0 turbo 4 cyl.:

Fuel Economy and Range

To lower fuel costs and make buying fuel easier, the GMC Acadia uses regular unleaded gasoline. The GLC requires premium, which can cost 20 to 55 cents more per gallon.

The Acadia FWD’s standard fuel tank has 2 gallons more fuel capacity than the GLC (19.4 vs. 17.4 gallons), for longer range between fill-ups. The Acadia AWD’s standard fuel tank has 4.3 gallons more fuel capacity than the GLC (21.7 vs. 17.4 gallons).

The Acadia has a standard cap-less fueling system. The fuel filler is automatically opened when the fuel nozzle is inserted and automatically closed when it’s removed. This eliminates the need to unscrew and replace the cap and it reduces fuel evaporation, which causes pollution. The GLC doesn’t offer a cap-less fueling system.

Tires and Wheels

The GMC Acadia’s wheels have 6 lugs for longer wheel bearing life, less chance of rotor warping and greater strength. The Mercedes GLC only has 5 wheel lugs per wheel.

The Acadia has a standard easy tire fill system. When inflating the tires, the vehicle’s integrated tire pressure sensors keep track of the pressure as the tires fill and tell the driver when the tires are inflated to the proper pressure. The GLC doesn’t offer vehicle monitored tire inflation.

The Acadia SLE/SLT/Denali has a standard space-saver spare tire so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the GLC; it requires you to depend on its run-flat tires, which limits mileage and speed before they are repaired. If a run-flat is damaged beyond repair by a road hazard your vehicle will have to be towed.

Suspension and Handling

The Acadia SLT AWD handles at .82 G’s, while the GLC 300 4MATIC pulls only .80 G’s of cornering force in a Motor Trend skidpad test.

The Acadia SLT AWD executes Motor Trend’s “Figure Eight” maneuver quicker than the GLC 300 4MATIC (26.9 seconds @ .67 average G’s vs. 27.3 seconds @ .65 average G’s).

For greater off-road capability the Acadia has a 2.2 inches greater minimum ground clearance than the GLC 300 (7.2 vs. 5 inches), allowing the Acadia to travel over rougher terrain without being stopped or damaged. The Acadia All Terrain’s minimum ground clearance is 1.1 inches higher than on the AMG GLC 43 (7.8 vs. 6.7 inches).


The Acadia uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The GLC doesn’t offer active noise cancellation.

As tested by Car and Driver while under full throttle, the interior of the Acadia Denali AWD is quieter than the AMG GLC 43 (78 vs. 80 dB).

Passenger Space

The Acadia has standard seating for 7 passengers; the GLC can only carry 5.

The Acadia has 2.5 inches more front headroom, .2 inches more front legroom, 2.1 inches more front shoulder room, 1.1 inches more rear headroom, 2.4 inches more rear legroom and 2.2 inches more rear shoulder room than the GLC.

The front step up height for the Acadia is 2 inches lower than the GLC (18” vs. 20”). The Acadia’s rear step up height is 3.5 inches lower than the GLC’s (19” vs. 22.5”).

Cargo Capacity

The Acadia’s cargo area provides more volume than the GLC.

41.7 cubic feet

The Acadia’s cargo area is larger than the GLC’s in almost every dimension:




Length to seat (3rd/2nd/1st)



Max Width







Maximum trailer towing in the Mercedes GLC is limited to 3500 pounds. The Acadia offers up to a 4000 lbs. towing capacity.


To improve rear visibility by keeping the rear window clear, the Acadia has a standard rear fixed intermittent wiper with a full on position. The rear wiper standard on the GLC only has an intermittent setting, so in a hard rain visibility isn’t as good.

Economic Advantages

Insurance will cost less for the Acadia owner. The Complete Car Cost Guide estimates that insurance for the Acadia will cost $580 to $6395 less than the GLC over a five-year period.

According to The Car Book by Jack Gillis, the Acadia is less expensive to operate than the GLC because typical repairs cost much less on the Acadia than the GLC, including $371 less for a water pump, $213 less for a muffler, $57 less for front brake pads, $287 less for a starter, $237 less for fuel injection, $11 less for a fuel pump, $305 less for front struts and $94 less for a power steering pump.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the GMC Acadia will be $9887 to $14525 less than for the Mercedes GLC.


The GMC Acadia outsold the Mercedes GLC by 27% during 2018.
