Small overlap front: driver-side

Rating applies to 2014-20 models

Tested vehicle: 2014 Acura RLX Navi 4-door

The Acura RL was redesigned for the 2014 model year after a one-year absence from the market and renamed the RLX.

Action shot taken during the driver-side 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 very 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.

Intrusion into the driver's space was minimal, and risk of injuries to the dummy's legs and feet was low.
