The X7’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Highlander doesn’t offer pre-crash pretensioners.
For enhanced safety, the middle seat shoulder belts of the BMW X7 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 Toyota Highlander doesn’t offer height-adjustable middle seat belts.
The BMW X7 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 Highlander doesn’t offer a front passenger side knee airbag.
To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the X7. But it costs extra on the Highlander.
The X7 has a standard blind spot warning system that uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them and moves the vehicle back into its lane. Only the Highlander LE/XLE/XSE/Limited/Platinum offers a blind spot warning system.
To help make backing out of a parking space safer, the X7 has standard Cross Traffic Warning with braking function and automatically engage the brakes. Only the Highlander LE/XLE/XSE/Limited/Platinum offers Rear Cross Traffic Alert.
Both the X7 and the Highlander 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, rearview cameras, driver alert monitors and available around view monitors.
The BMW X7 weighs 967 to 1841 pounds more than the Toyota Highlander. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
