The BMW X6 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 V90 Cross Country doesn’t offer a front passenger side knee airbag.
Over 200 people are killed each year when backed over by motor vehicles. The X6 offers optional Active Park Distance Control that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The V90 Cross Country doesn’t offer backup collision prevention brakes.
Both the X6 and the V90 Cross Country 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, all wheel drive, 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 X6 weighs 642 to 902 pounds more than the Volvo V90 Cross Country. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
