For enhanced safety, the front and rear seat shoulder belts of the Mercedes GLC 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 GLC’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.

The GLC 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 4Runner doesn’t offer front seat center airbags.

The GLC has standard Post-Collision Brake, which automatically apply the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The 4Runner 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.

Over 200 people are killed each year when backed over by motor vehicles. The GLC has a standard Maneuvering Brake Function that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The 4Runner doesn’t offer backup collision prevention brakes.

Earlier warning of stopped traffic, traffic signals, dangerous road conditions, weather, or accidents, can keep driver's safer and prevent crashes. The GLC offers optional Car-to-X Communication, a system that seamlessly communicates important warnings to the driver about impending danger, if they're available. The 4Runner doesn’t offer a system that can receive automated systems from infrastructure or other vehicles.

Both the GLC and 4Runner have Rear Cross-Traffic Alert, but the GLC has Active Brake Assist (automatically applies the brakes) to better prevent a collision when backing near traffic. The 4Runner’s Rear Cross-Traffic Alert doesn’t automatically brake.

For better protection of the passenger compartment, the GLC 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 GLC 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, 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 all wheel drive, lane departure warning systems and around view monitors.

A significantly tougher test than their original offset frontal crash test, the Insurance Institute for Highway Safety does 40 MPH small overlap frontal offset crash tests. In this test, where only 25% of the total width of the vehicle is struck, results indicate that the Mercedes GLC is safer than the 4Runner:

	GLC	4Runner
Overall Evaluation	GOOD	MARGINAL
Restraints	GOOD	GOOD
Head Neck Evaluation	GOOD	GOOD
Peak Head Forces	0 G’s	0 G’s
Steering Column Movement Rearward	0 cm	12 cm
Chest Evaluation	GOOD	GOOD
Hip & Thigh Evaluation	GOOD	GOOD
Femur Force R/L	.3/.6 kN	3.9/2.4 kN
Hip & Thigh Injury Risk R/L	0%/0%	1%/0%
Lower Leg Evaluation	GOOD	ACCEPTABLE
Tibia index R/L	.22/.36	.95/.85
Tibia forces R/L	1.4/1.2 kN	5/2.9 kN

The Mercedes GLC achieved a “Top Safety Pick” rating from the Insurance Institute for Highway Safety (IIHS) for the 2024 model year. This recognition was based on its impressive performance in the small overlap frontal crash test, updated side impact crash test, headlight evaluations, and pedestrian crash prevention testing. The 4Runner is not a “Top Safety Pick” for 2024.

Warranty

The GLC 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 GLC 300’s standard 2.0 turbo 4-cylinder hybrid produces 17 lbs.-ft. more torque (295 vs. 278) than the 4Runner’s 4.0 DOHC V6. The GLC 350e’s standard 2.0 turbo 4-cylinder hybrid produces 43 more horsepower (313 vs. 270) and 128 lbs.-ft. more torque (406 vs. 278) than the 4Runner’s 4.0 DOHC V6.

As tested in Car and Driver the GLC 300 is faster than the Toyota 4Runner:

	GLC	4Runner
Zero to 60 MPH	5.7 sec	7.8 sec
Zero to 100 MPH	16.2 sec	22 sec
5 to 60 MPH Rolling Start	6.6 sec	7.8 sec
Quarter Mile	14.4 sec	16.1 sec
Speed in 1/4 Mile	95 MPH	88 MPH
Top Speed	130 MPH	105 MPH

Fuel Economy and Range

On the EPA test cycle the GLC running on electricity gets better mileage than the 4Runner:

			MPGe
GLC
	AWD	350e Electric Motor	60 city/70 hwy
4Runner
			MPG
	RWD	4.0 DOHC V6	16 city/19 hwy
	AWD	4.0 DOHC V6	16 city/19 hwy

On the EPA test cycle the GLC running its gasoline engine gets better mileage than the 4Runner:

			MPG
GLC
	RWD	2.0 turbo 4-cyl. Hybrid	24 city/32 hwy
	AWD	2.0 turbo 4-cyl. Hybrid	23 city/31 hwy
		2.0 turbo 4-cyl. Hybrid	23 city/28 hwy
4Runner
	RWD	4.0 DOHC V6	16 city/19 hwy
	AWD	4.0 DOHC V6	16 city/19 hwy

The GLC 350e can travel with zero emissions for 54 miles. The 4Runner can’t move without running its internal combustion engine.

Regenerative brakes improve the GLC’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 GLC’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.

The GLC has a standard locking fuel door and a locking charge port on the 350e which lock and unlock with the power locks. The 4Runner 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.

Environmental Friendliness

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Mercedes GLC higher (6 out of 10) than the Toyota 4Runner (5). This means the GLC produces up to 6.9 pounds less smog-producing pollutants than the 4Runner every 15,000 miles.

Transmission

A nine-speed automatic is standard on the Mercedes GLC, 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 GLC’s brake rotors are larger than those on the 4Runner:

	GLC	4Runner
Front Rotors	13.5 inches	13.3 inches
Rear Rotors	12.6 inches	12.3 inches

The GLC stops much shorter than the 4Runner:

	GLC	4Runner
60 to 0 MPH	112 feet	138 feet	Motor Trend
60 to 0 MPH (Wet)	142 feet	145 feet	Consumer Reports

Tires and Wheels

The GLC’s standard tires provide better handling because they have a lower 60 series profile (height to width ratio) that provides a stiffer sidewall than the 4Runner’s standard 70 series tires. The GLC’s optional tires have a lower 45 series profile than the 4Runner Limited/TRD Sport’s 60 series tires.

For better ride, handling and brake cooling the GLC has standard 18-inch wheels. Smaller 17-inch wheels are standard on the 4Runner.

Suspension and Handling

For superior ride and handling, the Mercedes GLC 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 GLC has a standard automatic load leveling suspension to keep ride height level with a heavy load or when towing. The 4Runner doesn’t offer a load leveling suspension.

The GLC’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 GLC’s wheelbase is 3.3 inches longer than on the 4Runner (113.1 inches vs. 109.8 inches).

The GLC 300 4MATIC handles at .88 G’s, while the 4Runner TRD Off-Road pulls only .71 G’s of cornering force in a Car and Driver skidpad test.

The GLC 300 4MATIC executes Motor Trend’s “Figure Eight” maneuver 2.2 seconds quicker than the 4Runner TRD Off-Road (27.3 seconds @ .65 average G’s vs. 29.5 seconds @ .55 average G’s).

Chassis

The Mercedes GLC may be more efficient, handle and accelerate better because it weighs up to about 250 pounds less than the Toyota 4Runner.

The GLC is 4.5 inches shorter than the 4Runner, making the GLC easier to handle, maneuver and park in tight spaces.

Unibody construction lowers the GLC’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 doesn’t use unibody construction, but a body-on-frame design.

The design of the Mercedes GLC amounts to more than styling. The GLC 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 GLC get better fuel mileage.

Passenger Space

The GLC has 2 inches more front headroom, 2.5 inches more front hip room, 1.1 inches more rear headroom, 4.5 inches more rear legroom and 2.6 inches more rear hip room than the 4Runner.

Cargo Capacity

The GLC has a much larger cargo volume than the 4Runner with its rear seat up (21.9 vs. 9 cubic feet).

Pressing a button automatically lowers the GLC’s rear 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 GLC’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.

Servicing Ease

An ASSYST PLUS is standard on the GLC 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 engine computer on the GLC 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 GLC 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 GLC’s standard easy entry and exit feature 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 GLC offers an optional heads-up display that projects speed 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 GLC’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 GLC and the 4Runner have locks to prevent small children from operating them. When the lock on the GLC 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 GLC’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. Smart Key System standard on the 4Runner doesn’t offer a sensor on the rear doors, so you’ll have to reach a front handle to unlock the rear door.

The GLC’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 GLC’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.

Heated windshield washer fluid is optional on the GLC to defrost the washer nozzles and quickly clear ice and frost from the windshield without scraping. The 4Runner doesn’t offer heated windshield washer fluid.

The GLC 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 see further while navigating curves, the GLC offers optional adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle. The 4Runner doesn’t offer cornering lights.

The GLC’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 GLC 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 GLC’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.

Both the Mercedes GLC and Toyota 4Runner offer exterior mirrors that can be folded to provide convenience. The GLC features standard power folding mirrors, which allow for easy, one-touch folding or unfolding at the driver’s discretion. This provides added convenience when maneuvering or parking, as well as when walking past the parked vehicle. In comparison, the 4Runner’s foldable mirrors are manual, requiring the driver to get out and physically fold them once parked and unfold them before getting in.

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

The GLC 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.

The Mercedes GLC 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. Homelink® is only available on the 4Runner Premium/Limited/TRD Pro.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Mercedes GLC has a standard wireless phone charging system (Qi) in the front center console. The 4Runner doesn’t offer wireless personal charging.

The GLC’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.

Recommendations

Motor Trend selected the GLC as their 2017 Sport Utility of the Year. The 4Runner has never been chosen.
