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 QX80 are reminded to check the back seat if they opened the rear door before starting out. The XC90 doesn’t offer a back seat reminder.
The Infiniti QX80 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 XC90 doesn’t offer a front passenger side knee airbag.
The QX80 Autograph 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 XC90 doesn’t offer front seat center airbags.
Both the QX80 and the XC90 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, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors and available all wheel drive.
The Infiniti QX80 weighs 658 to 1496 pounds more than the Volvo XC90. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
