For enhanced safety, the front and second-row seat shoulder belts of the Mercedes GLE 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 GLE offers optional Post-Collision Brake, which automatically apply 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.

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

Earlier warning of stopped traffic, traffic signals, dangerous road conditions, weather, or accidents, can keep driver's safer and prevent crashes. The GLE has Car-to-X Communication, a system that seemlesly communicates important warnings to the driver about impending danger, if they're available. The Acadia doesn’t offer a system that can receive automated systems from other vehicles.

Both the GLE and Acadia have rear cross-traffic warning, but the GLE 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 GLE’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 GLE 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, plastic fuel tanks, 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.

The National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the Mercedes GLE is safer than the GMC Acadia:

New test not comparable to pre-2011 test results. More stars = Better. Lower test results = Better.

The Mercedes GLE (only applies to vehicles with optional Active Brake Assist with Cross-Traffic Function) has achieved the Insurance Institute for Highway Safety’s (IIHS) highest rating of “Top Safety Pick Plus” for the 2024 model year. This distinction is based on its exceptional performance in IIHS’ rigorous battery of safety tests. Specifically, it earned a “Good” rating in the latest, more stringent moderate overlap front crash test, a “Good” result in the updated side impact test, and an “Acceptable” score in the revised pedestrian crash prevention test. The Acadia is not even a standard “Top Safety Pick” for 2024.

Warranty

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

Engine

The GLE has more powerful engines than the Acadia:

	Horsepower	Torque
GLE 350 2.0 turbo 4-cylinder hybrid	255 HP	295 lbs.-ft.
GLE 450 3.0 turbo 6-cylinder hybrid	362 HP	369 lbs.-ft.
GLE 450e 2.0 turbo 4-cylinder hybrid	381 HP	479 lbs.-ft.
GLE 580 4.0 turbo V8 hybrid	510 HP	538 lbs.-ft.
Acadia 2.0 turbo 4-cylinder	228 HP	258 lbs.-ft.
Acadia 3.6 DOHC V6	310 HP	271 lbs.-ft.

Fuel Economy and Range

On the EPA test cycle the GLE running its gasoline engine gets better mileage than the Acadia:

			MPG
GLE
	AWD	350 2.0 turbo 4-cyl. Hybrid	21 city/28 hwy
Acadia
	FWD	3.6 DOHC V6	19 city/27 hwy
	AWD	3.6 DOHC V6	19 city/26 hwy

The GLE 450e can travel with zero emissions for 48 miles. The Acadia can’t move without running its internal combustion engine.

The GLE 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.

Brakes and Stopping

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

	GLE 350	GLE 450e	Acadia
Front Rotors	13 inches	15.7 inches	12.6 inches
Rear Rotors	13 inches	13.6 inches	12.4 inches

The GLE stops much shorter than the Acadia:

	GLE	Acadia
60 to 0 MPH	115 feet	126 feet	Motor Trend

Tires and Wheels

For better traction, the GLE has larger standard tires than the Acadia (255/50R19 vs. 235/65R18). The GLE 580’s optional tires are larger than the largest tires available on the Acadia (F:285/40R22 & R:325/35R22 vs. 255/65R17).

The GLE’s standard tires provide better handling because they have a lower 50 series profile (height to width ratio) that provides a stiffer sidewall than the Acadia SLE/SLT’s standard 65 series tires. The GLE 580’s optional 285/40R22 front and 325/35R22 rear tires have a lower 40 series front and 35 series rear profile than the Acadia’s optional 55 series tires.

For better ride, handling and brake cooling the GLE has standard 19-inch wheels. Smaller 17-inch wheels are standard on the Acadia AT4. The GLE 580’s optional 22-inch wheels are larger than the 20-inch wheels optional on the Acadia.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires available on the GLE 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.

Suspension and Handling

The GLE 450 offers an available adjustable active suspension system, which counteracts cornering forces actively, limiting body roll and improving handling and stability. GMC doesn’t offer an active suspension on the Acadia.

The GLE has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The GLE’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 Acadia doesn’t offer a load leveling suspension.

The GLE’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.

For a smoother ride and more stable handling, the GLE’s wheelbase is 5.4 inches longer than on the Acadia (117.9 inches vs. 112.5 inches).

For better handling and stability, the track (width between the wheels) on the GLE is 1.1 inches wider in the front and 1.9 inches wider in the rear than on the Acadia.

The GLE’s front to rear weight distribution is more even (53.5% to 46.5%) than the Acadia’s (56.5% to 43.5%). This gives the GLE more stable handling and braking.

The GLE 450 handles at .83 G’s, while the Acadia SLT AWD pulls only .82 G’s of cornering force in a Motor Trend skidpad test.

For greater off-road capability the GLE has a greater minimum ground clearance than the Acadia (7.9 vs. 7.2 inches), allowing the GLE to travel over rougher terrain without being stopped or damaged. The GLE Airmatic’s minimum ground clearance is 2 inches higher than on the Acadia (9.2 vs. 7.2 inches).

Passenger Space

The GLE has .5 inches more front headroom and 1.2 inches more rear legroom than the Acadia.

Cargo Capacity

The GLE has a much larger cargo volume than the Acadia with its rear seat up (33.3 vs. 12.8 cubic feet).

A low lift-over cargo hatch design makes loading and unloading the GLE easier. The GLE’s cargo hatch lift-over height is 30.7 inches, while the Acadia’s liftover is 32 inches.

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

Towing

The GLE’s standard towing capacity is much higher than the Acadia’s (7700 vs. 1000 pounds).

Optional Trailer Stability Assist on the GLE 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.

Servicing Ease

The engine in the GLE 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.

Ergonomics

Unlike the driver-only memory seat and mirrors in the Acadia (except SLE), the GLE has standard driver and 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 GLE’s standard easy entry system 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 GLE’s instruments include an oil pressure gauge and a temperature gauge - which could save your engine! Often ‘idiot lights’ don’t warn you until damage has been done. The Acadia does not have an oil pressure gauge.

The GLE’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 GLE 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 GLE’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.

Heated windshield washer nozzles are optional on the GLE to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The Acadia doesn’t offer heated windshield washer nozzles.

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 GLE’s headlights were rated “Good” by the IIHS, while the Acadia’s headlights are rated “Marginal.”

To help drivers avoid possible obstacles, the GLE offers optional cornering lights to illuminate around corners when the turn signals are activated. The Acadia doesn’t offer cornering lights. The GLE also offers optional adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle.

To better shield the driver and front passenger’s vision, the GLE has standard dual-element sun visors that can block glare from two directions simultaneously. The Acadia doesn’t offer secondary sun visors.

The GLE offers optional massaging front seats in order to maximize comfort and eliminate fatigue on long trips. Massaging seats aren’t available in the Acadia.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Mercedes GLE has a standard wireless phone charging system (Qi) in the center console. Wireless charging costs extra on the Acadia.

The GLE’s Active Parking Assist can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. The Acadia doesn’t offer an automated parking system.

Economic Advantages

Insurance will cost less for the GLE owner. The Car Book by Jack Gillis rates the GLE with a number “8” insurance rate while the Acadia is rated higher at a number “10” rate.

According to The Car Book by Jack Gillis, the GLE is less expensive to operate than the Acadia because it costs $154 less to do the manufacturer’s suggested maintenance for 50,000 miles. Typical repairs cost much less on the GLE than the Acadia, including $803 less for a timing belt/chain.
