The X4’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Forester doesn’t offer pre-crash pretensioners.

The BMW X4 has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Forester doesn’t offer a front passenger side knee airbag.

The X4 has a standard PostCrash iBrake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Forester 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.

The X4 offers an optional Surround View to allow the driver to see objects all around the vehicle on a screen. The Forester 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 X4 has a standard blind spot warning system which 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. A system to reveal vehicles in the Forester’s blind spot costs extra.

To help make backing out of a parking space safer, the X4 has a standard rear cross-path warning system, which uses sensors in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. Rear cross-path warning costs extra on the Forester and isn't available on the not available.

Compared to metal, the X4’s plastic fuel tank can withstand harder, more intrusive impacts without leaking; this decreases the possibility of fire. The Subaru Forester has a metal gas tank.

Both the X4 and the Forester have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, 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 and rearview cameras.

The BMW X4 weighs 558 to 949 pounds more than the Subaru Forester. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.

Warranty

The X4 comes with a full 4-year/50,000-mile basic warranty, which covers the entire truck and includes 24-hour roadside assistance. The Forester’s 3-year/36,000-mile basic warranty expires 1 year or 14,000 miles sooner.

The X4’s corrosion warranty is 7 years longer than the Forester’s (12 vs. 5 years).

BMW pays for scheduled maintenance on the X4 for 3 years and 36,000 miles. BMW will pay for oil changes, lubrication and any other required maintenance. Subaru doesn’t pay scheduled maintenance for the Forester.

Reliability

J.D. Power and Associates rated the X4 third among compact premium SUVs in their 2022 Initial Quality Study. The Forester isn’t in the top three in its category.

J.D. Power and Associates’ 2022 Initial Quality Study of new car owners surveyed provide the statistics that show that BMW vehicles are better in initial quality than Subaru vehicles. J.D. Power ranks BMW above average in initial quality. With 26 more problems per 100 vehicles, Subaru is rated below average.

J.D. Power and Associates’ 2022 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that BMW vehicles are more reliable than Subaru vehicles. J.D. Power ranks BMW above average in long-term dependability. With 5 more problems per 100 vehicles in the first three years of ownership, Subaru is rated below average.

Engine

The X4 xDrive30i’s standard 2.0 turbo 4-cylinder produces 66 more horsepower (248 vs. 182) and 82 lbs.-ft. more torque (258 vs. 176) than the Forester’s 2.5 DOHC 4-cylinder. The X4 M40i’s standard 3.0 turbo 6-cylinder hybrid produces 200 more horsepower (382 vs. 182) and 193 lbs.-ft. more torque (369 vs. 176) than the Forester’s 2.5 DOHC 4-cylinder.

Fuel Economy and Range

Regenerative brakes improve the X4’s fuel efficiency by converting inertia back into energy instead of wasting it. The Forester doesn’t offer a regenerative braking system.

Brakes and Stopping

For better stopping power the X4’s brake rotors are larger than those on the Forester:

	X4 xDrive30i	X4 M40i	Forester	Forester Premium/Sport/Wilderness/Limited/Touring
Front Rotors	13 inches	13.7 inches	11.6 inches	12.4 inches
Rear Rotors	13 inches	13.6 inches	11.2 inches	11.2 inches

The X4’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs on the Forester are solid, not vented.

The X4 stops much shorter than the Forester:

	X4	Forester
60 to 0 MPH	109 feet	129 feet	Motor Trend

Tires and Wheels

For better traction, the X4 has larger standard tires than the Forester (245/50R19 vs. 225/60R17). The X4’s optional tires are larger than the largest tires available on the Forester (F:245/45R20 & R:275/40R20 vs. 225/60R17).

The X4’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 Forester’s standard 60 series tires. The X4’s optional 245/40R21 front and 275/35R21 rear tires have a lower 40 series front and 35 series rear profile than the Forester Sport/Limited/Touring’s 55 series tires.

For better ride, handling and brake cooling the X4 has standard 19-inch wheels. Smaller 17-inch wheels are standard on the Forester. The X4’s optional 21-inch wheels are larger than the 18-inch wheels on the Forester Sport/Limited/Touring.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the X4 can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The Forester doesn’t offer run-flat tires.

Suspension and Handling

The X4 offers an optional 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 Forester’s suspension doesn’t offer adjustable shock absorbers.

For a smoother ride and more stable handling, the X4’s wheelbase is 7.7 inches longer than on the Forester (112.8 inches vs. 105.1 inches).

For better handling and stability, the average track (width between the wheels) on the X4 is 2 inches wider in the front and 3.5 inches wider in the rear than the average track on the Forester.

The X4’s front to rear weight distribution is more even (50.2% to 49.8%) than the Forester’s (57.3% to 42.7%). This gives the X4 more stable handling and braking.

The X4 M40i handles at .89 G’s, while the Forester Touring pulls only .79 G’s of cornering force in a Motor Trend skidpad test.

The X4 M40i executes Motor Trend’s “Figure Eight” maneuver 2.5 seconds quicker than the Forester Touring (25.6 seconds @ .73 average G’s vs. 28.1 seconds @ .6 average G’s).

Cargo Capacity

To make loading groceries and cargo easier when your hands are full, the X4’s available liftgate can be opened and closed just by kicking your foot under the back bumper, leaving your hands completely free. The Forester doesn’t offer a hands-free gesture to open its liftgate, forcing you to put cargo down if your hands are full.

Servicing Ease

The X4 uses gas struts to support the hood for easier service access. The Forester 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.

J.D. Power and Associates surveys of service recipients show that BMW service is better than Subaru. J.D. Power ranks BMW 7th in service department satisfaction (above the industry average). With a 14% lower rating, Subaru is ranked 16th.

Ergonomics

The X4 offers an optional heads-up display that projects speed, 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 Forester doesn’t offer a heads-up display.

The power windows standard on both the X4 and the Forester have locks to prevent small children from operating them. When the lock on the X4 is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The Forester prevents the driver from operating the other windows just as it does the other passengers.

The X4’s front and rear power windows all open or close fully with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside the car. The Forester’s standard passenger windows don’t open or close automatically. With the Forester Premium/Sport/Wilderness/Limited/Touring’s power windows, only the front windows open or close automatically.

If the windows are left open on the X4 the driver can close them all at the outside door handle or from a distance using the remote. On a hot day the driver can lower the windows from a distance using the keyless remote or with the driver’s door power window switch. The driver of the Forester can only operate the windows from inside the vehicle, with the ignition on.

The X4’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 Forester’s manually variable intermittent wipers have to be constantly adjusted.

The X4’s standard outside mirrors include heating elements to clear off the mirrors for better visibility. Subaru only offers heated mirrors on the Forester Premium/Sport/Wilderness/Limited/Touring.

Optional air-conditioned seats in the X4 keep the driver and front passenger comfortable and take the sting out of hot seats in Summer. The Forester doesn’t offer air-conditioned seats.

The X4 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 Forester Wilderness/Limited/Touring.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the BMW X4 offers an optional wireless phone charging system (Qi) in the center console. The Forester doesn’t offer wireless personal charging.

The X4’s optional Parking Assistant Plus can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. The Forester doesn’t offer an automated parking system.

Recommendations

J.D. Power and Associates rated the X4 second among compact premium SUVs in owner reported satisfaction. This includes how well the vehicle performs and satisfies its owner’s expectations. The Forester isn’t in the top three in its category.
