Compare the2025 Subaru OutbackVS 2024 BMW X4

For enhanced safety, the front and rear seat shoulder belts of the Subaru Outback 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 BMW X4 doesn’t offer pretensioners for its rear seat belts.

For enhanced safety, the front seat shoulder belts of the Subaru Outback 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 BMW X4 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 Outback are reminded to check the back seat if they opened the rear door before starting out. The X4 doesn’t offer a back seat reminder.

Both the Outback and the X4 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, available blind spot warning systems, rear parking sensors, rear cross-path warning and driver alert monitors.

The Subaru Outback 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 X4 has not yet been evaluated by the IIHS for 2024.

Subaru’s powertrain warranty covers the Outback 1 year and 10,000 miles longer than BMW covers the X4. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 5 years or 60,000 miles. Coverage on the X4 ends after only 4 years or 50,000 miles.

There are over 83 percent more Subaru dealers than there are BMW dealers, which makes it much easier should you ever need service under the Outback’s warranty.

The X4’s redline is at 7000 RPM, which causes more engine wear, and a greater chance of a catastrophic engine failure. The Outback has a 6000 RPM redline.

The Outback XT/Wilderness’ standard 2.4 turbo 4-cylinder produces 12 more horsepower (260 vs. 248) and 19 lbs.-ft. more torque (277 vs. 258) than the X4 xDrive30i’s standard 2.0 turbo 4-cylinder.

The flat cylinder configuration of the boxer engine in the Outback lowers its center of gravity, enhancing handling stability (That’s why Porsche uses boxer engines.). The X4 doesn’t offer a boxer engine configuration.

On the EPA test cycle the Outback gets better mileage than the X4:

To lower fuel costs and make buying fuel easier, the Subaru Outback uses regular unleaded gasoline (premium recommended on Outback XT/Wilderness for maximum performance). The X4 requires premium, which can cost on average about 82.8 cents more per gallon.

The Outback 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 X4 doesn’t offer a CVT.

The Outback Wilderness/Onyx XT has a standard full size spare tire so a flat doesn’t interrupt your trip. A full size spare isn’t available on the X4; it requires you to depend on a temporary spare or run-flat tires, either of which has mileage and speed limitations.

For better maneuverability, the Outback’s turning circle is 3.6 feet tighter than the X4’s (36.1 feet vs. 39.7 feet).

For greater off-road capability the Outback has a greater minimum ground clearance than the X4 (8.7 vs. 8 inches), allowing the Outback to travel over rougher terrain without being stopped or damaged. The Outback Wilderness’ minimum ground clearance is 1.5 inches higher than on the X4 (9.5 vs. 8 inches).

In case you lock your keys in your vehicle, or don’t have them with you, you can let yourself in using the Outback’s available exterior PIN entry system (not available on Outback Base). The X4 doesn’t offer an exterior PIN entry system, and its BMW Assist can’t unlock the doors if the vehicle doesn’t have cell phone reception or the driver can’t contact the service.

To improve rear visibility by keeping the rear window clear, the Outback has a standard rear wiper. The X4 doesn’t offer a rear wiper.

Manual rear side window sunshades are available in the Outback to help block heat and glare for the rear passengers. The X4 doesn’t offer rear side window sunshades.
