Small overlap front: driver-side

Rating applies to 2016-18 models

Tested vehicle: 2016 Acura RDX 4-door 4wd

The Acura RDX was redesigned for the 2013 model year. Beginning with 2016 models, the RDX was re-engineered with front-end and occupant compartment structural modifications to improve occupant protection in both small overlap and moderate overlap frontal crashes.

Driver restraints and dummy kinematics

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.

The driver's space was maintained well, and risk of injuries to the dummy's legs and feet was low.

Moderate overlap front: original test

Rating applies to 2016-18 models

Tested vehicle: 2016 Acura RDX Technology 4-door 4wd

The Acura RDX was redesigned for the 2013 model year. Beginning with 2016 models, the RDX was re-engineered with front-end and occupant compartment structural modifications 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 as part of frontal crash test verification. (The car tested by Honda was designated as a 2013 model but included all modifications applied to the 2016 models.)
