Tested vehicle: 2007 Audi A4 Cabriolet 2.0T 2-door convertible

The Audi A4 Cabriolet was redesigned for the 2003 model year. Knee airbags in the lower instrument panel designed to minimize knee injuries in frontal crashes were added beginning with 2007 models.

Driver restraints and dummy kinematics

Action shot taken during the frontal offset crash test.

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

During rebound, the dummy's head hit only the head restraint, as indicated by smeared greasepaint.

Intrusion into the driver's space was minimal, and all leg and foot injury measures were low. The deployed driver knee airbag is clearly visible.

Rear passenger head protection The dummy's head was hit by the interior side trim. This impact did not produce high head injury measures, but the head protection is inadequate.

View of the vehicle and barrier just after the crash test.

View of the vehicle after the crash with door removed, showing the side airbag, pop-up rollover bars, and damage to the occupant compartment.

Smeared greasepaint shows where the driver dummy's head was protected from being hit by hard structures by the side airbag.

Smeared yellow, red, and green greasepaint shows where the rear passenger dummy’s head was hit by the interior side trim.
