For enhanced safety, the front and rear seat shoulder belts of the Subaru Forester 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.

For enhanced safety, the front seat shoulder belts of the Subaru Forester 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 Forester 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.

Over 200 people are killed each year when backed over by motor vehicles. The Forester (except Base/Premium) offers optional Reverse Automatic Braking 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.

The Forester Touring has a standard 360-Degree Surround View Monitor to allow the driver to see objects all around the vehicle on a screen. The Grenadier only offers a rear monitor and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the front or sides.

The Forester (except Base)’s optional 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 and moves the vehicle back into its lane. 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 Forester (except Base)’s optional Rear Cross Traffic Alert uses sensors in the rear to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The Grenadier doesn’t offer a rear cross-path warning system.

For better protection of the passenger compartment, the Forester 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 Forester 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, all wheel drive, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras and available driver alert monitors.

The Subaru Forester 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 an “Acceptable” rating in the latest, more stringent moderate overlap front crash test, a “Good” result in the updated side impact test, and a “Good” score in the revised pedestrian crash prevention test. The Grenadier has not yet been evaluated by the IIHS for 2024.

Warranty

There are almost 32 times as many Subaru dealers as there are INEOS dealers, which makes it much easier should you ever need service under the Forester’s warranty.

Reliability

The Grenadier’s redline is at 7000 RPM, which causes more engine wear, and a greater chance of a catastrophic engine failure. The Forester has a 6000 RPM redline.

Engine

As tested in Motor Trend the Subaru Forester is faster than the INEOS Grenadier:

	Forester	Grenadier
Zero to 60 MPH	8.8 sec	8.9 sec
Quarter Mile	16.7 sec	16.8 sec
Speed in 1/4 Mile	86.3 MPH	80.8 MPH

The flat cylinder configuration of the boxer engine in the Forester lowers its center of gravity, enhancing handling stability without compromising ground clearance. The Grenadier doesn’t offer a boxer engine configuration.

Fuel Economy and Range

On the EPA test cycle the Forester gets better mileage than the Grenadier:

		MPG
Forester
	2.5 DOHC flat-4	26 city/33 hwy
	Sport/Touring 2.5 DOHC flat-4	25 city/32 hwy
Grenadier
	3.0 turbo 6-cyl.	15 city/15 hwy
	Trailmaster 3.0 turbo 6-cyl.	14 city/14 hwy

To lower fuel costs and make buying fuel easier, the Subaru Forester uses regular unleaded gasoline. The Grenadier requires premium, which can cost on average about 84.9 cents more per gallon.

The Forester 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

The Forester has a standard continuously variable transmission (CVT). With no “steps” between gears, it can keep the engine at the most efficient speed for fuel economy, or keep it at its peak horsepower indefinitely for maximum acceleration. The Grenadier doesn’t offer a CVT.

Brakes and Stopping

The Forester’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 Forester stops much shorter than the Grenadier:

	Forester	Grenadier
60 to 0 MPH	131 feet	152 feet	Motor Trend

Tires and Wheels

The Forester’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 Forester Sport/Touring’s tires have a lower 50 series profile than the Grenadier’s 70 series tires.

For better ride, handling and brake cooling the Forester Sport/Touring has standard 19-inch wheels. The Grenadier’s largest wheels are only 18-inches.

Suspension and Handling

The Subaru Forester’s independent front suspension is much lighter than the INEOS Grenadier’s solid front axle, which allows the Forester’s wheels to react more quickly and accurately to the road’s surface, improving both ride and handling.

For superior ride and handling, the Subaru Forester 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.

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

The Forester Sport handles at .80 G’s, while the Grenadier Trailmaster pulls only .60 G’s of cornering force in a Motor Trend skidpad test.

The Forester Sport executes Motor Trend’s “Figure Eight” maneuver 3.9 seconds quicker than the Grenadier Trailmaster (27.6 seconds @ .61 average G’s vs. 31.5 seconds @ .49 average G’s).

For better maneuverability, the Forester’s turning circle is 9 feet tighter than the Grenadier’s (35.4 feet vs. 44.4 feet).

Chassis

The Subaru Forester may be more efficient, handle and accelerate better because it weighs about 2150 to 2300 pounds less than the INEOS Grenadier.

The Forester is 12.6 inches shorter in height than the Grenadier, making the Forester much easier to wash and garage and drive (lower center of gravity).

Unibody construction lowers the Forester’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.

To almost totally eliminate engine vibration in the passenger area, the Forester has liquid-filled engine mounts. The liquid helps further dampen engine harshness. The Grenadier uses conventional solid rubber engine mounts.

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

The front grille of the Forester uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The Grenadier doesn’t offer active grille shutters.

Passenger Space

The Forester has 1.8 inches more front headroom, 4 inches more front legroom, .2 inches more rear headroom and 9 inches more rear legroom than the Grenadier.

For enhanced passenger comfort on long trips the Forester Premium/Sport/Limited/Touring’s rear seats recline. The Grenadier’s rear seats don’t recline.

Cargo Capacity

The Forester has a larger cargo volume with its rear seat folded than the Grenadier with its rear seat folded (74.4 vs. 71 cubic feet).

A low lift-over cargo hatch design makes loading and unloading the Forester easier. The Forester’s cargo hatch lift-over height is 28.9 inches, while the Grenadier’s liftover is 35.3 inches.

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

	Forester	Grenadier
Length to seat (2nd/1st)	36.5”/70.7”	31.4”/64.7”
Max Width	51.2”	49.9”
Min Width	43.3”	41.8”
Height	34.9”	41.2”

Pulling a handle automatically lowers the Forester Limited/Touring’s rear seats, to make changing between passengers and cargo easier. The Grenadier doesn’t offer automatic folding seats.

The Forester’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 Forester’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

A maintenance reminder system is standard on the Forester to save the owner time and money by calculating maintenance intervals for oil changes, tire rotation, and vehicle inspections, 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 Forester Premium/Sport/Limited/Touring 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 Forester 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 two different drivers share the Forester Touring, the memory system makes it convenient for both. Each setting activates different, customized memories for the driver’s seat position, outside mirror angle and climate settings. The Grenadier doesn’t offer a memory system.

The Forester Touring’s standard easy entry system glides the driver’s seat back when the door is unlocked or the ignition is switched off, making it easier for the driver to get in and out. The Grenadier doesn’t offer an easy entry system.

The Forester’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 Forester’s standard power windows have a locking feature to keep children from operating them. INEOS does not offer a locking feature on the Grenadier’s standard power windows.

The Forester’s standard driver’s power window opens or closes with one touch of the window control, making it more convenient at drive-up windows and toll booths. The Grenadier’s power windows’ switch has to be held the entire time to close it fully. The Forester Premium/Sport/Limited/Touring’s front power windows both open or close with one touch of the switches.

The Keyless Access and Start standard on the Forester Premium/Sport/Limited/Touring allows you to unlock the doors from either front door handle, unlock the cargo door, and start the engine, all without removing the key from the pocket or purse. The INEOS Grenadier doesn’t offer an advanced key system.

While driving with high beams on, sensitive light sensors standard on the Forester 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 Forester has standard adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle. The Grenadier doesn’t offer cornering lights.

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the Forester has standard extendable sun visors. The Grenadier doesn’t offer extendable visors.

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

When the Forester Touring 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 Forester’s optional 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 Forester and the Grenadier offer available heated front seats. The Forester Touring also has standard heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the Grenadier.

Standard air-conditioned seats in the Forester Touring 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 Forester Limited/Touring’s standard 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 Forester Premium/Sport/Limited/Touring 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 Forester’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 Forester has a standard Adaptive Cruise Control, 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 Subaru Forester eliminates the need for separate garage door openers and associated risks of losing, breaking, or having dead batteries with its optional 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 Subaru Forester Premium/Sport/Limited/Touring has a standard wireless phone charging system (Qi) in the front center console. The Grenadier doesn’t offer wireless personal charging.
