The X4’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Highlander Hybrid doesn’t offer pre-crash pretensioners.
The BMW X4 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 Hybrid 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 X4. But it costs extra on the Highlander Hybrid.
When descending a steep, off-road slope, the X4’s standard Hill Descent Control allows you to creep down safely. The Highlander Hybrid doesn’t offer Hill Descent Control.
Both the X4 and the Highlander Hybrid have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, plastic fuel tanks, 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.
