The XM’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The CX-90 doesn’t offer pre-crash pretensioners.
To help make backing out of a parking space safer, the XM has standard Cross Traffic Warning with braking function with automatic braking, systems which detect vehicles approaching from the sides and can automatically apply the brakes to prevent a collision. Only the CX-90 Premium Plus/Turbo S Premium offers Rear Cross Traffic Braking.
Both the XM and the CX-90 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, 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 820 to 1354 pounds more than the Mazda CX-90. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
