The BMW XM has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags help 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 Q6 e-tron doesn’t offer knee airbags.
Over 200 people are killed each year when backed over by motor vehicles. The XM has a standard Active Park Distance Control that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Q6 e-tron doesn’t offer automatic braking for stationary objects directly to the rear.
To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the XM. But it costs extra on the Q6 e-tron.
When descending a steep, off-road slope, the XM’s standard Hill Descent Control allows you to creep down safely. The Q6 e-tron doesn’t offer Hill Descent Control.
Both the XM and the Q6 e-tron have standard driver and passenger frontal airbags, front side-impact 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 and driver alert monitors.
The BMW XM weighs 674 to 1109 pounds more than the Audi Q6 e-tron. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
