The Subaru Ascent has a standard driver’s side knee airbag mounted low on the dashboard. The knee airbag helps prevent the driver from sliding under the seatbelts or the main frontal airbag; this keeps the driver better positioned during a collision for maximum protection. A knee airbag also helps keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Navigator doesn’t offer knee airbags.
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 Lincoln Navigator has not been tested.
The Subaru Ascent’s rear backup camera has a standard washer for maintaining a clear view under various conditions. In contrast, the Lincoln Navigator does not offer a rear camera washer, meaning its effectiveness relies on manual cleaning by the user when necessary.
For better protection of the passenger compartment, the Ascent 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 Navigator uses a body-on-frame design, which has no frame members above the floor of the vehicle.
Both the Ascent and the Navigator have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front and rear seatbelt pretensioners, height adjustable front shoulder belts, 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, blind spot warning systems, rearview cameras, rear cross-path warning, available around view monitors and driver alert monitors.
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 Navigator has not yet been fully evaluated by the IIHS for 2026.
