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 Cadillac XT6 doesn’t offer pretensioners for its second-row seat belts.

With its available Active Brake Assist with Cross-Traffic Function, the Mercedes GLE is better at preventing collisions with pedestrians than the Cadillac XT6, according to the Insurance Institute for Highway Safety:

	GLE	XT6
Overall Evaluation	ACCEPTABLE	MARGINAL
	Crossing Child - DAY
12 MPH	AVOIDED	AVOIDED
25 MPH	AVOIDED	-23 MPH
	Crossing Adult - NIGHT
12 MPH Brights	AVOIDED	-7 MPH
12 MPH Low beams	AVOIDED	-4 MPH
25 MPH Brights	AVOIDED	-24 MPH
25 MPH Low beams	-23 MPH	-1 MPH
	Parallel Adult - NIGHT
37 MPH Brights	AVOIDED	-13 MPH

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 XT6 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.

When descending a steep, off-road slope, the GLE’s standard Downhill Speed Regulation allows you to creep down safely. The XT6 doesn’t offer Downhill Speed Regulation.

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 XT6 doesn’t offer a system that can receive automated systems from other vehicles.

Both the GLE and XT6 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 XT6’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 XT6 doesn’t offer a driver alert monitor.

Both the GLE and the XT6 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 Cadillac XT6:

	GLE	XT6

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

Side impacts caused 23% of all road fatalities in 2018, down from 29% in 2003, when the Insurance Institute for Highway Safety introduced its side barrier test. In order to continue improving vehicle safety, the IIHS has started using a more severe side impact test: 37 MPH (up from 31 MPH), with a 4180-pound barrier (up from 3300 pounds). The results of this newly developed test demonstrates that the Mercedes GLE is much safer than the XT6:

	GLE	XT6

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 XT6 is not even a standard “Top Safety Pick” for 2024.

Reliability

J.D. Power and Associates’ 2024 Initial Quality Study of new car owners surveyed provide the statistics that show that Mercedes vehicles are better in initial quality than Cadillac vehicles. With 8 fewer problems per 100 vehicles, JD Power ranks Mercedes higher than Cadillac.

Engine

The GLE has more powerful engines than the XT6:

	Horsepower	Torque
GLE 350 2.0 turbo 4-cylinder hybrid	255 HP	295 lbs.-ft.
GLE 450 3.0 turbo 6-cylinder hybrid	375 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.
XT6 2.0 turbo 4-cylinder	235 HP	258 lbs.-ft.
XT6 Premium Luxury/Sport 3.6 DOHC V6	310 HP	271 lbs.-ft.

As tested in Motor Trend the Mercedes GLE is faster than the XT6 Premium Luxury/Sport 3.6 DOHC V6:

	GLE 450	GLE 450e	XT6
Zero to 60 MPH	5.6 sec	5.5 sec	6.8 sec
Quarter Mile	14.2 sec	14 sec	15.2 sec
Speed in 1/4 Mile	97.4 MPH	98.2 MPH	93.1 MPH

Fuel Economy and Range

On the EPA test cycle the GLE running on electricity gets better mileage than the XT6:

			MPGe
GLE
	AWD	450e Electric Motor	57 city/63 hwy
XT6
			MPG
	FWD	2.0 turbo 4-cyl.	21 city/27 hwy

		3.6 DOHC V6	19 city/26 hwy
	AWD	3.6 DOHC V6	18 city/25 hwy

The GLE 450e can travel with zero emissions for 50 miles. The XT6 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 XT6 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 XT6 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.

Brakes and Stopping

For better stopping power the GLE’s brake rotors are larger than those on the XT6:

	GLE	XT6
Front Rotors	14.8 inches	12.6 inches
Rear Rotors	13.6 inches	12.4 inches

The GLE stops much shorter than the XT6:

	GLE	XT6
60 to 0 MPH	115 feet	131 feet	Motor Trend

Tires and Wheels

For better traction, the GLE has larger standard tires than the XT6 (255/50R19 vs. 235/55R20). The GLE 580’s optional tires are larger than the largest tires available on the XT6 (F:285/40R22 & R:325/35R22 vs. 265/45R21).

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 XT6’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 XT6 Premium Luxury/Sport’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 XT6. The GLE 580’s optional 22-inch wheels are larger than the 21-inch wheels optional on the XT6 Premium Luxury/Sport.

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 XT6 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. Cadillac doesn’t offer an active suspension on the XT6.

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 XT6 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 XT6 doesn’t offer drift compensation steering.

For a smoother ride and more stable handling, the GLE’s wheelbase is 5.2 inches longer than on the XT6 (117.9 inches vs. 112.7 inches).

The GLE 450 handles at .83 G’s, while the XT6 Sport AWD pulls only .82 G’s of cornering force in a Motor Trend skidpad test.

For greater off-road capability the GLE has a 1.2 inches greater minimum ground clearance than the XT6 (7.9 vs. 6.7 inches), allowing the GLE to travel over rougher terrain without being stopped or damaged. The GLE Airmatic’s minimum ground clearance is 2.5 inches higher than on the XT6 (9.2 vs. 6.7 inches).

Chassis

The GLE is 4.2 inches shorter than the XT6, making the GLE easier to handle, maneuver and park in tight spaces.

Passenger Space

The GLE has .7 inches more front headroom, 1 inch more front shoulder room, 1.8 inches more rear legroom and .9 inches more rear shoulder room than the XT6.

Cargo Capacity

The GLE has a much larger cargo volume than the XT6 with its rear seat up (33.3 vs. 12.6 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 XT6’s liftover is 33 inches.

Towing

The GLE’s standard towing capacity is much higher than the XT6’s (7700 vs. 1000 pounds).

Servicing Ease

The engine in the GLE is mounted longitudinally (North-South), instead of sideways, as in the XT6. 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 system in the XT6, 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 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 XT6 does not have an oil pressure gauge.

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 XT6’s rear power window switches have to be held the entire time to close them fully.

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 (remote must be aimed at door sensor). On a hot day the driver can lower the windows from a distance using the keyless remote. The driver of the XT6 can only close 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 XT6’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 XT6 doesn’t offer heated windshield washer fluid.

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 XT6’s headlights are rated “Acceptable.”

The XT6’s cornering lamps activate a lamp on the front corner when the turn signal is activated. The GLE’s optional adaptive cornering lights turn the actual headlight unit up to several degrees, depending on steering wheel angle and vehicle speed. This lights a significant distance into corners at any speed.

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 XT6 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 XT6 doesn’t offer rear side window sunshades.

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 XT6.

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. Only the XT6 Premium Luxury/Sport offers wireless charging.

The GLE offers an optional 115-volt a/c outlet on the center console, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The XT6 doesn’t offer a house-current electrical outlet.

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 XT6 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 XT6 because it costs $200 less to do the manufacturer’s suggested maintenance for 50,000 miles. Typical repairs cost much less on the GLE than the XT6, including $77 less for a muffler and $693 less for a timing belt/chain.

Recommendations

The Mercedes GLE outsold the Cadillac XT6 by over three to one during 2023.
