Small overlap front: driver-side

Rating applies to 2016-22 models

Tested vehicle: 2016 Acura ILX Premium 4-door

The Acura ILX was introduced in the 2013 model year and is derived from the Honda Civic. Beginning with 2016 models, the ILX was re-engineered with structural and occupant restraint changes to improve occupant protection in both small overlap and moderate overlap frontal crashes.

Action shot taken during the small overlap frontal crash test.

The dummy's position in relation to the door frame, steering wheel, and instrument panel after the crash test indicates that the driver's survival space was maintained well.

The frontal and side curtain airbags worked well together to keep the head from coming close to any stiff structure or outside objects that could cause injury.

Forces during the crash contributed to a moderate risk of injury to the dummy's left lower leg.

About the small overlap front test

Moderate overlap front: original test

Rating applies to 2016-22 models

Tested vehicle: 2016 Acura ILX Technology 4-door

The Acura ILX was introduced in the 2013 model year and is derived from the Honda Civic. Beginning with 2016 models, the ILX was re-engineered with structural and occupant restraint changes to improve occupant protection in both small overlap and moderate overlap frontal crashes.

Moderate overlap frontal ratings are assigned by the Institute based on a test conducted by Honda.
