Small overlap front: driver-side
Rating applies to 2009-16 models
Tested vehicle: 2012 Audi A4 2.0T Premium 4-door 2wd
The Audi A4 was redesigned for the 2009 model year. Two tests of the A4 were conducted because, in the first test, the vehicle's electrical system did not deploy the airbags due to a crash test preparation error. As a result, ratings for restraints and dummy kinematics and dummy injuries are based only on the second test. Structural ratings are based on both tests.

| Driver restraints and dummy kinematics In the second test, the dummy’s head contacted the frontal airbag but slid off the left side as the steering column moved 18 cm to the right, leaving the head vulnerable to contact with forward structure and resulting in little airbag cushioning for the chest. The side curtain airbag deployed and had sufficient forward coverage to protect the head from contact with side structure and outside objects. The driver door opened during the crash, which shouldn't happen because the driver could be partly or completely ejected from the vehicle. |
Action shot taken during the second of two small overlap frontal crash tests.
The dummy's position in relation to the door frame, steering wheel, and instrument panel after the crash test indicates the driver's survival space wasn't maintained well (second test with front and side curtain airbag deployment).
In the second test, the dummy moved to the left and its head slid around the left side of the frontal airbag.
Extensive intrusion by the instrument panel and footwell contributed a high risk of injury to the dummy's left hip.

Moderate overlap front: original test
Rating applies to 2009-16 models
Tested vehicle: 2009 Audi A4 2.0T quattro 4-door 4wd
The Audi A4 was redesigned for the 2009 model year. Moderate overlap frontal ratings are assigned by the Institute based on a test conducted by Volkswagen/Audi.
The moderate overlap frontal crash test ratings also apply to the station wagon version of the A4, known as the A4 Avant, also redesigned for 2009.
