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 INEOS Grenadier doesn’t offer pretensioners for its rear 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 Grenadier doesn’t offer pre-crash pretensioners.

For enhanced safety, the front seat shoulder belts of the Mercedes GLC are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The INEOS Grenadier doesn’t offer height-adjustable seat belts.

In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the GLC are reminded to check the back seat if they opened the rear door before starting out. The Grenadier doesn’t offer a back seat reminder.

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 Grenadier 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 Grenadier 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 Grenadier 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 Grenadier doesn’t offer a system that can receive automated systems from infrastructure or other vehicles.

The GLC offers an optional Surround View System to allow the driver to see objects all around the vehicle on a screen. The Grenadier only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.

The GLC’s blind spot warning system uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. The Grenadier doesn’t offer a system to reveal objects in the driver’s blind spots.

To help make backing out of a parking space safer, the GLC’s standard Rear Cross-Traffic Alert uses sensors in the rear to alert the driver to vehicles approaching from the side and Active Brake Assist automatically engages the brakes to help avoid a collision. The Grenadier doesn’t offer a rear cross-path warning system.

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 Grenadier uses a body-on-frame design, which has no frame members above the floor of the vehicle.

Both the GLC and the Grenadier have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras, driver alert monitors, available all wheel drive and lane departure warning systems.

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 Grenadier has not yet been evaluated by the IIHS for 2024.

Warranty

There are over 19 times as many Mercedes dealers as there are INEOS dealers, which makes it much easier should you ever need service under the GLC’s warranty.

Engine

The GLC 350e’s standard 2.0 turbo 4-cylinder hybrid produces 31 more horsepower (313 vs. 282) and 74 lbs.-ft. more torque (406 vs. 332) than the Grenadier’s 3.0 turbo 6-cylinder.

As tested in Motor Trend the GLC 300 is faster than the INEOS Grenadier:

	GLC	Grenadier
Zero to 60 MPH	6.1 sec	8.9 sec
Quarter Mile	14.6 sec	16.8 sec
Speed in 1/4 Mile	93.8 MPH	80.8 MPH

Fuel Economy and Range

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

			MPGe
GLC
	AWD	350e Electric Motor	60 city/70 hwy
Grenadier
			MPG
	AWD	3.0 turbo 6-cyl.	15 city/15 hwy
		Trailmaster 3.0 turbo 6-cyl.	14 city/14 hwy

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

			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
Grenadier
	AWD	3.0 turbo 6-cyl.	15 city/15 hwy
		Trailmaster 3.0 turbo 6-cyl.	14 city/14 hwy

The GLC 350e can travel with zero emissions for 54 miles. The Grenadier 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 Grenadier doesn’t offer a regenerative braking system.

The GLC has a tether attaching its gas cap to prevent its loss. The Grenadier’s gas cap isn’t tethered, so it can be left at a gas station if the driver forgets to screw the cap back in.

Transmission

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

Brakes and Stopping

For better stopping power the GLC’s brake rotors are larger than those on the Grenadier:

	GLC	Grenadier
Front Rotors	13.5 inches	12.4 inches
Rear Rotors	12.6 inches	12 inches

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

The GLC stops much shorter than the Grenadier:

	GLC	Grenadier
60 to 0 MPH	112 feet	152 feet	Motor Trend

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 Grenadier’s standard 70 series tires. The GLC’s optional tires have a lower 45 series profile than the Grenadier’s 70 series tires.

For better ride, handling and brake cooling the GLC has standard 18-inch wheels. Smaller 17-inch wheels are standard on the Grenadier. The GLC’s optional 20-inch wheels are larger than the 18-inch wheels optional on the Grenadier.

Suspension and Handling

The Mercedes GLC’s independent front suspension is much lighter than the INEOS Grenadier’s solid front axle, which allows the GLC’s wheels to react more quickly and accurately to the road’s surface, improving both ride 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 INEOS Grenadier 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 Grenadier doesn’t offer a load leveling suspension.

For much better steering response and tighter handling the GLC has rack and pinion steering, like Formula racecars, instead of the recirculating-ball type steering of the Grenadier.

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 Grenadier doesn’t offer drift compensation steering.

The GLC 300 4MATIC handles at .87 G’s, while the Grenadier Trailmaster pulls only .60 G’s of cornering force in a Motor Trend skidpad test.

The GLC 300 4MATIC executes Motor Trend’s “Figure Eight” maneuver 4.2 seconds quicker than the Grenadier Trailmaster (27.3 seconds @ .65 average G’s vs. 31.5 seconds @ .49 average G’s).

For better maneuverability, the GLC’s turning circle is 5.7 feet tighter than the Grenadier’s (38.7 feet vs. 44.4 feet).

Chassis

The Mercedes GLC may be more efficient, handle and accelerate better because it weighs about 800 to 1650 pounds less than the INEOS Grenadier.

The GLC is 16.1 inches shorter in height than the Grenadier, making the GLC much easier to wash and garage and drive (lower center of gravity).

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 Grenadier doesn’t use unibody construction, but a body-on-frame design.

For excellent aerodynamics, the GLC has standard flush composite headlights. The Grenadier has recessed headlights that spoil its aerodynamic shape and create extra drag.

Passenger Space

The GLC has 1.9 inches more front headroom, 1.4 inches more front legroom, .3 inches more rear headroom and 7 inches more rear legroom than the Grenadier.

For enhanced passenger comfort on long trips the GLC’s rear seats recline. The Grenadier’s rear seats don’t recline.

Cargo Capacity

The GLC’s cargo area is larger than the Grenadier’s in almost every dimension:

	GLC	Grenadier
Length to seat (2nd/1st)	39.1”/67.4”	31.4”/64.7”
Height	29.2”	41.2”

Pressing a button automatically lowers the GLC’s rear seats, to make changing between passengers and cargo easier. The Grenadier doesn’t offer automatic folding seats.

The GLC’s liftgate lifts up in one piece, completely out of the way of loading and unloading, while sheltering the cargo loading area. The Grenadier’s two swing out doors impair rear visibility, need a lot of clearance, and can block loading in tight quarters.

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

Servicing Ease

The GLC uses gas struts to support the hood for easier service access. The Grenadier uses a prop rod to support its heavy hood. It takes two hands to open the hood and set the prop rod, the prop rod gets in the way during maintenance and service, and the prop rod could be knocked out, causing the heavy hood to fall on the person maintaining or servicing the car.

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. INEOS doesn’t offer a maintenance reminder on the Grenadier.

Ergonomics

The GLC 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 Grenadier doesn’t offer a remote starting system.

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 Grenadier’s starter can be accidentally engaged while the engine is running, making a grinding noise and possibly damaging the starter and ring gear.

When three different drivers share the GLC, the memory system makes it convenient for all three. Each keyless remote activates different, customized memories for the driver and front passenger’s seat positions, steering wheel position and outside mirror angle. The Grenadier doesn’t offer a memory system.

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 Grenadier 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 Grenadier 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 Grenadier has a lever-type parking brake that has to be strenuously raised to engage properly. It has to be lifted up more and a button depressed to release it.

The GLC’s standard power windows have a locking feature to keep children in the rear seat from operating them, but the driver can still raise and lower all of them with the lock engaged. INEOS does not offer a locking feature on the Grenadier’s standard power windows.

The GLC’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 Grenadier’s power windows’ switches have to be held the entire time to close them fully.

Keyless-Go standard on the GLC allows 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. The INEOS Grenadier doesn’t offer an advanced key system.

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 Grenadier’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 Grenadier doesn’t offer heated windshield washer fluid. Its standard heated washer nozzles will defrost the washer fluid but not the windshield.

While driving with high beams on, sensitive light sensors standard on the GLC detect other vehicles which could be blinded and automatically switch to low beams. The Grenadier doesn’t offer automatic dimming high beams.

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 Grenadier doesn’t offer cornering lights.

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 Grenadier’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 Grenadier doesn’t offer the luxury of automatic dimming mirrors.

Both the Mercedes GLC and INEOS Grenadier 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 Grenadier’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 cost extra on the Grenadier. The GLC also offers optional heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the Grenadier.

Optional air-conditioned seats in the GLC keep the driver and front passenger comfortable and take the sting out of hot seats in Summer. The Grenadier doesn’t offer air-conditioned seats.

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

The GLC has a standard center folding armrest for the rear passengers. A center armrest helps make rear passengers more comfortable and it can provide a boundary between children. The Grenadier doesn’t offer a rear seat center armrest.

The GLC’s 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. The Grenadier doesn’t offer dual zone air conditioning.

To keep a safe, consistent following distance, the GLC offers an optional Active Distance Assist Distronic, which alters the speed of the vehicle without driver intervention. This allows the driver to use cruise control more safely without constantly having to disengage it when approaching slower traffic. The Grenadier doesn’t offer an adaptive cruise control.

Compared to the INEOS Grenadier, the Mercedes GLC eliminates the need for separate garage door openers and associated risks of losing, breaking, or having dead batteries with its standard integrated Homelink® universal remote controlled from the rear view mirror.

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 Grenadier 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 Grenadier doesn’t offer an automated parking system.

Model Availability

The GLC is available in both rear-wheel drive and four-wheel drive configurations. The Grenadier doesn’t offer a two-wheel drive configuration.

Recommendations

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