The Q5’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The X2 doesn’t offer pre-crash pretensioners.
For enhanced safety, the front seat shoulder belts of the Audi Q5 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.
Both the Q5 and X2 have child safety locks to prevent children from opening the rear doors. The Q5 has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The X2’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.
The Insurance Institute for Highway Safety tests front crash prevention systems. With a score of 5 points, IIHS rates the Pre Sense Front in the Q5 as “Superior.” The X2 scores only 4 points and is rated only “Advanced.”
The Q5 has a standard Secondary Collision Brake Assist, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The X2 doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.
To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the Q5. But it costs extra on the X2.
The Q5 Premium Plus/Prestige has a standard Top View Camera System 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 Q5 has a standard blind spot warning system which uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. A system to reveal vehicles in the X2’s blind spot costs extra.
To help make backing out of a parking space safer, the Q5 has a standard rear cross-path warning system, which uses sensors in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. Rear cross-path warning costs extra on the X2.
Both the Q5 and the X2 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, 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.
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 Q5 its highest rating: “Top Pick Plus” for 2021, a rating granted to only 73 vehicles tested by the IIHS. The X2 has not been fully tested, yet.
