For enhanced safety, the front and rear seat shoulder belts of the Infiniti QX55 have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The BMW X2 doesn’t offer pretensioners for its rear seat belts.
For enhanced safety, the front seat shoulder belts of the Infiniti QX55 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 X2 doesn’t offer height-adjustable seat belts.
In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the QX55 are reminded to check the back seat if they opened the rear door before starting out. The X2 doesn’t offer a back seat reminder.
The Insurance Institute for Highway Safety tests front crash prevention systems. With a score of 6 points, IIHS rates the Forward Emergency Braking in the QX55 as “Superior.” The X2 scores only 4 points and is rated only “Advanced.”
Over 200 people are killed each year when backed over by motor vehicles. The QX55 has standard Rear Automatic Braking that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The X2 doesn’t offer backup collision prevention brakes.
To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the QX55. But it costs extra on the X2.
The QX55 Essential/Sensory has a standard Around View® Monitor to allow the driver to see objects all around the vehicle on a screen. The X2 only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.
The QX55’s blind spot warning system uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them and moves the vehicle back into its lane. The X2 doesn’t offer a system to reveal objects in the driver’s blind spots.
To help make backing out of a parking space safer, the QX55’s standard Rear Cross Traffic Alert uses sensors in the rear to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The X2 doesn’t offer a rear cross-path warning system.
Compared to metal, the QX55’s plastic fuel tank can withstand harder, more intrusive impacts without leaking; this decreases the possibility of fire. The BMW X2 has a metal gas tank.
Both the QX55 and the X2 have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems and rearview cameras.
