The BMW iX 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.
Over 200 people are killed each year when backed over by motor vehicles. The iX has standard Active Park Distance Control that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The XC90 doesn’t offer backup collision prevention brakes.
To provide maximum traction and stability on all roads, Full-Time Four-Wheel Drive is standard on the iX. But it costs extra on the XC90.
Both the iX and the XC90 have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, post-collision automatic braking systems, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors and available around view monitors.
The BMW iX weighs 574 to 1382 pounds more than the Volvo XC90. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
