The GLE’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Acadia doesn’t offer pre-crash pretensioners.

The Mercedes GLE has a standard driver’s side knee airbag mounted low on the dashboard. The knee airbag helps prevent the driver from sliding under the seatbelts or the main frontal airbag; this keeps the driver better positioned during a collision for maximum protection. A knee airbag also helps keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Acadia doesn’t offer knee airbags.

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.

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 seamlessly 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 the Acadia have standard driver and passenger frontal airbags, front side-impact 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, blind spot warning systems, around view monitors, rear cross-path warning and available lane departure warning systems.

The Mercedes GLE (with optional crash prevention) 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 has not yet been evaluated by the IIHS 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 450’s standard 3.0 turbo 6-cylinder hybrid produces 47 more horsepower (375 vs. 328) and 43 lbs.-ft. more torque (369 vs. 326) than the Acadia’s 2.5 turbo 4-cylinder. The GLE 450e’s standard 2.0 turbo 4-cylinder hybrid produces 53 more horsepower (381 vs. 328) and 153 lbs.-ft. more torque (479 vs. 326) than the Acadia’s 2.5 turbo 4-cylinder. The GLE 580’s standard 4.0 turbo V8 hybrid produces 182 more horsepower (510 vs. 328) and 212 lbs.-ft. more torque (538 vs. 326) than the Acadia’s 2.5 turbo 4-cylinder.

Fuel Economy and Range

On the EPA test cycle the GLE running on electricity gets better mileage than the Acadia:

			MPGe
GLE
	AWD	450e Electric Motor	57 city/63 hwy
Acadia
			MPG
	FWD	2.5 turbo 4-cyl.	20 city/27 hwy
	AWD	2.5 turbo 4-cyl.	19 city/24 hwy

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

			MPG
GLE
	RWD	350 2.0 turbo 4-cyl. Hybrid	21 city/28 hwy
	AWD	450e 2.0 turbo 4-cyl. Hybrid	21 city/26 hwy
		350 2.0 turbo 4-cyl. Hybrid	19 city/26 hwy
		3.0 turbo 6-cyl. Hybrid	19 city/25 hwy
Acadia
	FWD	2.5 turbo 4-cyl.	20 city/27 hwy
	AWD	2.5 turbo 4-cyl.	19 city/24 hwy

The GLE 450e can travel with zero emissions for 50 miles. The Acadia can’t move without running its internal combustion engine.

Regenerative brakes improve the GLE’s fuel efficiency by converting inertia back into energy instead of wasting it. The Acadia doesn’t offer a regenerative braking system.

The GLE has a standard locking fuel door and a locking charge port on the 350e which lock and unlock with the power locks. The Acadia doesn’t offer a locking fuel filler door. A locking fuel door helps prevent fuel theft and vandalism, such as sugar in the tank and a locking charge port prevents tampering and damage.

Transmission

A nine-speed automatic is standard on the Mercedes GLE, for better acceleration and lower engine speed on the highway. Only an eight-speed automatic is available for the Acadia.

Brakes and Stopping

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

	GLE	Acadia
Front Rotors	14.8 inches	12.6 inches
Rear Rotors	13.6 inches	12.4 inches

The GLE’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs on the Acadia are solid, not vented.

Tires and Wheels

For better traction, the GLE 580’s optional tires are larger than the largest tires available on the Acadia (F:285/40R22 & R:325/35R22 vs. 275/45R22).

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 AT4’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 Denali’s optional 45 series tires.

For better ride, handling and brake cooling the GLE has standard 19-inch wheels. Smaller 18-inch wheels are standard on the Acadia AT4.

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 450/580 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 offers an available driver-adjustable suspension system. It allows the driver to choose between an extra-supple ride, reducing fatigue on long trips, or a sport setting, which allows maximum control for tricky roads or off-road. The Acadia’s suspension doesn’t offer adjustable shock absorbers.

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 greater off-road capability the GLE has a 1.1 inches greater minimum ground clearance than the Acadia Elevation (7.9 vs. 6.8 inches), allowing the GLE to travel over rougher terrain without being stopped or damaged. The GLE Airmatic’s minimum ground clearance is 1.4 inches higher than on the Acadia AT4 (9.2 vs. 7.8 inches).

Chassis

The GLE is 9.7 inches shorter than the Acadia, making the GLE easier to handle, maneuver and park in tight spaces.

Cargo Capacity

The GLE has a much larger cargo volume than the Acadia with its rear seat up (33.3 vs. 23 cubic feet).

Towing

The GLE’s standard towing capacity is much higher than the Acadia’s (7700 vs. 5000 pounds).

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 the accessory belts are in front.

Ergonomics

Unlike the driver-only memory seat and mirrors in the Acadia Denali, the GLE has standard driver and passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position, outside mirror angle and radio stations and the front passenger seat also adjusts to the new passenger’s preset preferences.

The GLE’s front and rear power windows all open or close with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside of the car. The Acadia’s passenger windows don’t close automatically.

The GLE’s standard Keyless-Go allow you to unlock the doors from any outside door handle, open the cargo door, and start the vehicle, all without removing the key from the pocket or purse. Keyless Access standard on the Acadia doesn’t offer a sensor on the rear doors, so you’ll have to reach a front handle to unlock the rear door.

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 standard manually variable intermittent wipers have to be constantly adjusted.

Heated windshield washer fluid is optional on the GLE to defrost the washer nozzles and quickly clear ice and frost from the windshield without scraping. The Acadia doesn’t offer heated windshield washer fluid.

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.

Manual rear side window sunshades are available in the GLE to help block heat and glare for the rear passengers. The Acadia doesn’t offer rear side window sunshades.

When the GLE 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 Acadia’s mirror doesn’t automatically adjust for backing.

The Mercedes GLE has power folding mirrors that offer unparalleled convenience while maneuvering in tight places or parked. With the mirrors folded it’s easier to walk past and help prevent parking damage. The mirrors can be quickly unfolded when the driver is ready to leave. Power folding mirrors are only offered on the Acadia Denali.

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.

The Mercedes GLE has a standard Homelink wireless remote control system for garage door operation and device management, conveniently located on the rear view mirror. Homelink® eliminates the need for separate garage door openers and associated risks of losing, breaking, or having dead batteries. GMC charges extra for Homelink® on the Acadia.
