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 Outback 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 Outback 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 Outback 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 Outback only offers a rear monitor.

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 Outback’s blind spot costs extra.

To help make backing out of a parking space safer, the X4 has a standard 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. Cross-path warning costs extra on the Outback 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 Outback has a metal gas tank.

Both the X4 and the Outback 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.

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 Outback’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 Outback’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 Outback.

Reliability

J.D. Power and Associates rated the X4 first among compact premium suvs in their 2021 Initial Quality Study. The Outback isn’t in the top three in its category.

J.D. Power and Associates’ 2021 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 20th in initial quality. With 16 more problems per 100 vehicles, Subaru is ranked 24th.

J.D. Power and Associates’ 2021 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 10th in reliability, above the industry average. With 17 more problems per 100 vehicles, Subaru is ranked 17th.

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 Outback 2.5i’s standard 2.5 DOHC 4-cylinder. The X4 M40i’s standard 3.0 turbo 6-cylinder hybrid produces 122 more horsepower (382 vs. 260) and 92 lbs.-ft. more torque (369 vs. 277) than the Outback XT/Wilderness’ standard 2.4 turbo 4-cylinder.

Fuel Economy and Range

On the EPA test cycle the X4 xDrive30i 2.0 turbo 4-cylinder gets better fuel mileage than the Outback XT/Wilderness Wilderness 2.4 turbo flat-4 (21 city/28 hwy vs. 22 city/26 hwy).

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

Environmental Friendliness

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the BMW X4 higher (5 to 7 out of 10) than the Subaru Outback (3 to 7). This means the X4 produces up to 24.5 pounds less smog-producing pollutants than the Outback every 15,000 miles.

Brakes and Stopping

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

	X4 xDrive30i	X4 M40i	Outback
Front Rotors	13 inches	13.7 inches	12.4 inches
Rear Rotors	13 inches	13.6 inches	11.8 inches

The X4 stops much shorter than the Outback:

	X4	Outback
60 to 0 MPH	109 feet	132 feet	Motor Trend

Tires and Wheels

For better traction, the X4 has larger standard tires than the Outback (245/50R19 vs. 225/65R17). The X4’s optional tires are larger than the largest tires available on the Outback (F:245/44R20 & R:275/40R20 vs. 225/65R17).

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 Outback’s standard 65 series tires. The X4 M40i’s optional 245/40R21 front and 275/35R21 rear tires have a lower 40 series front and 35 series rear profile than the Outback Onyx Edition XT/Limited/Touring’s 60 series tires.

For better ride, handling and brake cooling the X4 has standard 19-inch wheels. Smaller 17-inch wheels are standard on the Outback. The X4 M40i’s optional 21-inch wheels are larger than the 18-inch wheels on the Outback Onyx Edition XT/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 Outback 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 Outback’s suspension doesn’t offer adjustable shock absorbers.

The X4 has vehicle speed sensitive variable-assist power steering, for low-effort parking, better control at highway speeds and during hard cornering, and a better feel of the road. The Outback doesn’t offer variable-assist power steering.

For a smoother ride and more stable handling, the X4’s wheelbase is 4.7 inches longer than on the Outback (112.8 inches vs. 108.1 inches).

For better handling and stability, the average track (width between the wheels) on the X4 is 1.6 inches wider in the front and 2.3 inches wider in the rear than the average track on the Outback.

The X4 M40i handles at .89 G’s, while the Outback Limited XT pulls only .75 G’s of cornering force in a Motor Trend skidpad test.

The X4 M40i executes Motor Trend’s “Figure Eight” maneuver 2.8 seconds quicker than the Outback Limited (25.6 seconds @ .73 average G’s vs. 28.4 seconds @ .62 average G’s).

Chassis

The X4 is 3.7 inches shorter than the Outback, making the X4 easier to handle, maneuver and park in tight spaces.

Cargo Capacity

Pulling a handle automatically lowers the X4’s rear seats, to make changing between passengers and cargo easier. The Outback doesn’t offer automatic folding seats.

Servicing Ease

The X4 uses gas struts to support the hood for easier service access. The Outback 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 8th in service department satisfaction (above the industry average). With a 23% lower rating, Subaru is ranked 22nd.

Ergonomics

The X4 offers a 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 Outback doesn’t offer a remote starting system.

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 Outback doesn’t offer a heads-up display.

The power windows standard on both the X4 and the Outback 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 Outback prevents the driver from operating the rear 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 Outback’s standard rear power window switches have to be held the entire time to open or close them fully.

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 Outback 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 Outback’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 Outback Premium/Limited/Wilderness/Touring/Onyx.

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 Outback Premium/Limited/Wilderness/Touring/Onyx.

Both the X4 and the Outback offer rear vents. For greater rear passenger comfort, the X4 has standard rear air conditioning vents to keep rear occupants cool in summer or warm in winter. The Outback doesn’t offer rear air conditioning vents, only heat vents.

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 Outback doesn’t offer an automated parking system.
