The Ascent has standard Whiplash-Reducing Front Seats, which use a specially designed seat to protect the driver and front passenger from whiplash. During a rear-end collision, the Whiplash-Reducing Front Seats system allows the backrest to travel backwards to cushion the occupants and the headrests move forward to prevent neck and spine injuries. The Outlander doesn’t offer a whiplash protection system.
In a Vehicle-to-Vehicle Frontal Crash Prevention 2.0 test conducted by the Insurance Institute for Highway Safety (IIHS), the Subaru Ascent achieved a “Good” rating - the highest possible - for its performance in forward collision warning and automatic braking systems, demonstrating its excellent capabilities in preventing collisions. The Mitsubishi Outlander has not been tested.
To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the Ascent. But it costs extra on the Outlander.
The Subaru Ascent’s rear backup camera has a standard washer for maintaining a clear view under various conditions. In contrast, the Mitsubishi Outlander does not offer a rear camera washer, meaning its effectiveness relies on manual cleaning by the user when necessary.
Both the Ascent and the Outlander have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, blind spot warning systems, rearview cameras, rear cross-path warning, available around view monitors and driver alert monitors.
The Subaru Ascent weighs 442 to 820 pounds more than the Mitsubishi Outlander. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
The Insurance Institute for Highway Safety does 40 MPH moderate front offset crash tests on new cars. In this updated test, results indicate that the Ascent is much safer than the Outlander:

The Subaru Ascent has achieved the Insurance Institute for Highway Safety’s (IIHS) highest rating of “Top Safety Pick Plus” for the 2026 model year. This distinction is based on its exceptional performance in IIHS’ rigorous battery of safety tests. Specifically, it earned a “Good” rating in the latest, more stringent moderate overlap front crash test, a “Good” result in the updated side impact test, a “Good” score in the revised pedestrian crash prevention test, and a “Good” score in the revised vehicle-to-vehicle crash prevention test. The Outlander is not even a standard “Top Safety Pick” for 2026.
