The QX60 Luxe’s optional pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The CX-9 doesn’t offer pre-crash pretensioners.
For enhanced safety, the front, middle and rear seat shoulder belts of the Infiniti QX60 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 Mazda CX-9 doesn’t offer height-adjustable middle or rear seat belts.
Over 200 people are killed each year when backed over by motor vehicles. The QX60 Luxe offers an optional Backup Collision Intervention that use rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The CX-9 doesn’t offer backup collision prevention brakes.
Compared to metal, the QX60’s plastic fuel tank can withstand harder, more intrusive impacts without leaking; this decreases the possibility of fire. The Mazda CX-9 has a metal gas tank.
Both the QX60 and the CX-9 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, front wheel drive, height-adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, blind spot warning systems, rearview cameras, rear cross-path warning, available all-wheel drive, lane departure warning systems and around view monitors.
