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 Toyota 4Runner doesn’t offer pretensioners for its second-row seat belts.

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 4Runner doesn’t offer pre-crash pretensioners.

For better protection of the passenger compartment, the GLE uses safety cell construction with a three-dimensional high-strength frame that surrounds the passenger compartment. It provides extra impact protection and a sturdy mounting location for door hardware and side impact beams. The 4Runner uses a body-on-frame design, which has no frame members above the floor of the vehicle.

Both the GLE and the 4Runner 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, driver alert monitors, available lane departure warning systems and around view monitors.

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 Toyota 4Runner:

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

Instrumented handling tests conducted by the National Highway Traffic Safety Administration and analysis of its dimensions indicate that the GLE, with its four-star roll-over rating, is 9.1% less likely to roll over than the 4Runner, which received a three-star rating.

For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, with its optional vehicle-to-vehicle front crash prevention system, with its optional vehicle-to-pedestrian front crash prevention system, and its standard headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the GLE its highest rating: “Top Safety Pick Plus” for 2022, a rating granted to only 114 vehicles tested by the IIHS. The 4Runner is not even a standard “Top Safety Pick.”

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 4Runner’s 3-year/36,000-mile basic warranty expires 1 year or 14,000 miles sooner.

Engine

The GLE 450’s standard 3.0 turbo 6-cylinder hybrid produces 92 more horsepower (362 vs. 270) and 91 lbs.-ft. more torque (369 vs. 278) than the 4Runner’s 4.0 DOHC V6. The GLE 580’s standard 4.0 turbo V8 hybrid produces 213 more horsepower (483 vs. 270) and 238 lbs.-ft. more torque (516 vs. 278) than the 4Runner’s 4.0 DOHC V6.

As tested in Motor Trend the Mercedes GLE is faster than the Toyota 4Runner:

	GLE 350	GLE 450	4Runner
Zero to 60 MPH	7.6 sec	5.6 sec	7.8 sec
Quarter Mile	15.8 sec	14.2 sec	15.9 sec
Speed in 1/4 Mile	87.5 MPH	97.4 MPH	87.3 MPH

Fuel Economy and Range

On the EPA test cycle the GLE gets better mileage than the 4Runner:

			MPG
GLE
	RWD	2.0 turbo 4-cyl.	20 city/25 hwy
	AWD	3.0 turbo 6-cyl. Hybrid	20 city/25 hwy
		2.0 turbo 4-cyl.	20 city/24 hwy
		4.0 turbo V8 Hybrid	16 city/21 hwy
4Runner
	RWD	4.0 DOHC V6	16 city/19 hwy
	AWD	4.0 DOHC V6	16 city/19 hwy

Regenerative brakes improve the GLE 450/580’s fuel efficiency by converting inertia back into energy instead of wasting it. The 4Runner doesn’t offer a regenerative braking system.

In heavy traffic or at stoplights the GLE’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. If the conditions warrant or the driver wishes, the system can be manually disabled at any time for the duration of a trip. The 4Runner doesn’t offer an automatic engine start/stop system.

Environmental Friendliness

The U.S. Environmental Protection Agency (EPA) certifies the Mercedes GLE as an “Ultra Low Emissions Vehicle” (ULEV). The Toyota 4Runner is only certified to “Low Emissions Vehicle” (LEV) standards.

Transmission

A nine-speed automatic is standard on the Mercedes GLE, for better acceleration and lower engine speed on the highway. Only a five-speed automatic is available for the 4Runner.

Brakes and Stopping

For better stopping power the GLE 450/580’s brake rotors are larger than those on the 4Runner:

	GLE 450/580	4Runner
Front Rotors	14.8 inches	13.3 inches
Rear Rotors	13.6 inches	12.3 inches

The GLE stops much shorter than the 4Runner:

	GLE	4Runner
70 to 0 MPH	174 feet	201 feet	Car and Driver
60 to 0 MPH	115 feet	138 feet	Motor Trend
60 to 0 MPH (Wet)	138 feet	145 feet	Consumer Reports

Tires and Wheels

For better traction, the GLE has larger standard tires than the 4Runner (255/50R19 vs. 245/60R20). The GLE’s optional tires are larger than the largest tires available on the 4Runner (F:275/45R21 & R:315/40R21 vs. 265/70R17).

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 4Runner’s standard 70 series tires. The GLE 450’s optional tires have a lower 40 series profile than the 4Runner Limited/TRD Sport’s 60 series tires.

For better ride, handling and brake cooling the GLE has standard 19-inch wheels. Smaller 17-inch wheels are standard on the 4Runner. The GLE 450’s optional 22-inch wheels are larger than the 20-inch wheels on the 4Runner Limited/TRD Sport.

Suspension and Handling

For superior ride and handling, the Mercedes GLE has fully independent front and rear suspensions. An independent suspension allows the wheels to follow the road at the best angle for gripping the pavement, without compromising ride comfort. The Toyota 4Runner has a solid rear axle, with a non-independent rear suspension.

The GLE 450 offers an available adjustable active suspension system, which counteracts cornering forces actively, limiting body roll and improving handling and stability. Toyota doesn’t offer an active suspension on the 4Runner.

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 4Runner’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 4Runner 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 4Runner doesn’t offer drift compensation steering.

For a smoother ride and more stable handling, the GLE’s wheelbase is 8.1 inches longer than on the 4Runner (117.9 inches vs. 109.8 inches).

For better handling and stability, the track (width between the wheels) on the GLE is 1.9 inches wider in the front and 2.8 inches wider in the rear than the average track on the 4Runner.

The GLE 450 handles at .84 G’s, while the 4Runner TRD Off-Road pulls only .71 G’s of cornering force in a Car and Driver skidpad test.

The GLE 450 executes Motor Trend’s “Figure Eight” maneuver 2.5 seconds quicker than the 4Runner TRD Off-Road (27 seconds @ .69 average G’s vs. 29.5 seconds @ .55 average G’s).

Chassis

Unibody construction lowers the GLE’s center of gravity significantly without reducing ground clearance. This contributes to better on the road handling and better off-road performance and stability. In addition, unibody construction makes the chassis stiffer, improving handling and reducing squeaks and rattles. The 4Runner uses body-on-frame design instead.

The design of the Mercedes GLE amounts to more than styling. The GLE has an aerodynamic coefficient of drag of .29 Cd. That is significantly lower than the 4Runner (.36) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the GLE get better fuel mileage.

As tested by Car and Driver, the interior of the GLE 450 is quieter than the 4Runner TRD Off-Road:

	GLE	4Runner
At idle	38 dB	43 dB
Full-Throttle	70 dB	76 dB
70 MPH Cruising	63 dB	69 dB

Passenger Space

The GLE has 1.2 inches more front headroom, 1.5 inches more front shoulder room, 1 inch more rear headroom, 8 inches more rear legroom and .5 inches more rear shoulder room than the 4Runner.

Cargo Capacity

The GLE has a much larger cargo volume than the 4Runner with its rear seat up (33.3 vs. 9 cubic feet).

A control in the cargo area automatically lowers the GLE’s second row seats, to make changing between passengers and cargo easier. The 4Runner doesn’t offer automatic folding seats.

To make loading and unloading groceries and cargo easier when your hands are full, the GLE’s power liftgate can be opened or closed just by kicking your foot under the back bumper, leaving your hands completely free. The 4Runner doesn’t offer a power or hands-free opening liftgate.

Towing

The GLE’s standard towing capacity is much higher than the 4Runner’s (5950 vs. 5000 pounds). Maximum trailer towing in the Toyota 4Runner is only 5000 pounds. The GLE offers up to a 7700 lbs. towing capacity.

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 4Runner doesn’t offer electronic trailer sway control.

Servicing Ease

An ASSYST PLUS is standard on the GLE to save the owner time and money by calculating maintenance intervals for oil changes, tire rotation and brake pad replacement based on odometer mileage. This takes the guesswork out of keeping your vehicle in top condition and helps it last longer. Toyota doesn’t offer a maintenance reminder on the 4Runner.

Ergonomics

The GLE has a standard remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The 4Runner doesn’t offer a remote starting system.

The engine computer on the GLE automatically engages the starter until the car starts with one twist of the key and disables the starter while the engine is running. The 4Runner’s starter can be accidentally engaged while the engine is running, making a grinding noise and possibly damaging the starter and ring gear.

Unlike the driver-only memory seat in the 4Runner Limited, the GLE 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 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. The 4Runner doesn’t offer an easy entry system.

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 4Runner does not have an oil pressure gauge.

The GLE offers an optional heads-up display that projects speed, tachometer, certain gauge, warning and navigation instruction readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The 4Runner doesn’t offer a heads-up display.

The GLE’s power parking brake sets with one touch and releases with one touch or automatically. The 4Runner’s parking brake has to be released manually.

The power windows standard on both the GLE and the 4Runner have locks to prevent small children from operating them. When the lock on the GLE is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The 4Runner prevents the driver from operating the other windows just as it does the other passengers.

The GLE’s power window, power lock, power mirror and cruise control switches are lit from behind, making them plainly visible and easier to operate at night. The 4Runner’s power mirror and cruise control switches are unlit, making them difficult to find at night and operate safely.

The GLE has a standard locking fuel door with a remote release located convenient to the driver. A locking fuel door helps prevent fuel theft and vandalism, such as sugar in the tank. The 4Runner doesn’t offer a locking fuel 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 4Runner’s manually variable intermittent wipers have to be constantly adjusted.

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” to “Acceptable” by the IIHS, while the 4Runner’s headlights are rated “Poor.”

The GLE has a standard automatic headlight on/off feature. When the ignition is on, the headlights automatically turn on at dusk and off after dawn. The 4Runner has an automatic headlight on/off feature standard only on the Limited/TRD Pro.

To help drivers avoid possible obstacles, the GLE offers optional cornering lights to illuminate around corners when the turn signals are activated. The 4Runner 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 4Runner 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 4Runner doesn’t offer rear side window sunshades.

The GLE’s power mirror controls are mounted on the armrest for easy access. The 4Runner’s power mirror controls are on the dash where they are possibly hidden by the steering wheel and are awkward to manipulate.

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 4Runner’s mirror doesn’t automatically adjust for backing.

The GLE’s standard rear and side view mirrors have an automatic dimming feature. These mirrors can be set to automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The 4Runner offers an automatic rear view mirror, but its side mirrors don’t dim.

The GLE has standard heated front seats. Heated front seats are only available on the 4Runner Premium/Limited/TRD Pro. The GLE also offers optional heated second row seats to keep those passengers extremely comfortable in the winter. Heated second row seats aren’t available in the 4Runner.

On extremely cold winter days, the GLE’s optional heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the vehicle heater warms up. The 4Runner doesn’t offer a heated steering wheel.

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 4Runner.

The GLE has a standard dual zone air conditioning allows the driver and front passenger to choose two completely different temperatures so people with different temperature preferences won’t have to compromise. This makes both the driver and front passenger as comfortable as possible. Dual zone air conditioning is only available on the 4Runner Limited/TRD Pro.

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. The 4Runner doesn’t offer wireless personal charging.

The GLE’s Active Parking Assist can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. The 4Runner 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 4Runner 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 4Runner because typical repairs cost much less on the GLE than the 4Runner, including $47 less for a fuel pump and $1313 less for a timing belt/chain.
