The QX60 Luxe’s optional pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Ascent doesn’t offer pre-crash pretensioners.
For enhanced safety, the front, middle and rear seat shoulder belts of the Infiniti QX60 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 Subaru Ascent doesn’t offer height-adjustable middle seat belts.
The QX60 offers an optional Around View® Monitor to allow the driver to see objects all around the vehicle on a screen. The Ascent only offers a rear monitor and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the front or sides.
Both the QX60 and the Ascent have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, rearview cameras, available all-wheel drive and lane departure warning systems.
For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, and with its optional front crash prevention system, the Insurance Institute for Highway Safety grants the QX60 the rating of “Top Pick” for 2017, a rating granted to only 140 vehicles tested by the IIHS. The Ascent has not been tested, yet.
