For enhanced safety, the front seat shoulder belts of the Acura ILX 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 MINI Cooper Hardtop 4 Door doesn’t offer height-adjustable seat belts.
The ILX has standard Active Head Restraints, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Active Head Restraints system moves the headrests forward to prevent neck and spine injuries. The Cooper Hardtop 4 Door doesn’t offer a whiplash protection system.
The Insurance Institute for Highway Safety tests front crash prevention systems. With a score of 5 points, IIHS rates the Collision Mitigating Braking System in the ILX as “Superior.” The Cooper Hardtop 4 Door scores only 4 points and is rated only “Advanced.”
The ILX’s optional 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. The Cooper Hardtop 4 Door 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 ILX’s optional cross-path warning system uses sensors in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The Cooper Hardtop 4 Door doesn’t offer a cross-path warning system.
Both the ILX and the Cooper Hardtop 4 Door have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, front wheel drive, plastic fuel tanks, 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 all IIHS frontal, side, rear impact and roof-crush tests, and its standard front crash prevention system, the Insurance Institute for Highway Safety grants the ILX the rating of “Top Pick” for 2017, a rating granted to only 213 vehicles tested by the IIHS. The Cooper Hardtop 4 Door has not been fully tested, yet.
