The Nissan Armada 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 Ascent doesn’t offer a front passenger side knee airbag.
The Armada Platinum Reserve has a standard front seat center airbag, which deploys between the driver and front passenger, protecting them from injuries caused by striking each other in serious side impacts. The Ascent doesn’t offer front seat center airbags.
The Armada has a standard blind spot warning system that 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. Only the Ascent Premium/Onyx/Limited/Touring offers a blind spot warning system.
To help make backing out of a parking space safer, the Armada has standard Rear Cross Traffic Alert, helping the driver avoid collisions. Only the Ascent Premium/Onyx/Limited/Touring offers Rear Cross Traffic Alert.
Both the Armada and the Ascent 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, lane departure warning systems, rearview cameras, available all wheel drive and around view monitors.
The Nissan Armada weighs 1087 to 1690 pounds more than the Subaru Ascent. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
