The X5’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The CX-50 doesn’t offer pre-crash pretensioners.
The X5 has standard Active Head Restraints, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Active Head Restraints system moves the headrests forward to prevent neck and spine injuries. The CX-50 doesn’t offer a whiplash protection system.
When descending a steep, off-road slope, the X5’s standard Hill Descent Control allows you to creep down safely. The CX-50 doesn’t offer Hill Descent Control.
To help make backing out of a parking space safer, the X5 has standard Cross Traffic Warning with Braking with automatic braking, systems which detect vehicles approaching from the sides and can automatically apply the brakes to prevent a collision. Only the CX-50 Turbo Premium Plus offers Rear Cross Traffic Braking.
Both the X5 and the CX-50 have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger 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 X5 weighs 1208 to 1475 pounds more than the Mazda CX-50. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
