For enhanced safety, the front seat shoulder belts of the Mazda CX-9 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 BMW X7 doesn’t offer height-adjustable front seat belts.
Over 200 people are killed each year when backed over by motor vehicles. The CX-9 Carbon Edition/Grand Touring/Signature has standard Rear Smart City Brake Support that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The X7 doesn’t offer backup collision prevention brakes.
Both the CX-9 and the X7 have standard driver and passenger frontal airbags, front side-impact 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, available around view monitors and driver alert monitors.
For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard vehicle-to-vehicle front crash prevention system, its standard vehicle-to-pedestrian front crash prevention system, and its standard headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the CX-9 its highest rating: “Top Pick Plus” for 2021, a rating granted to only 74 vehicles tested by the IIHS. The X7 has not been tested, yet.
