Moderate overlap front

Rating applies to 2002-08 models built after February 2002

Tested vehicle: 2002 Audi A4 1.8T quattro 4-door 4wd

The Audi A4 was redesigned for the 2002 model year. Audi A4s manufactured after February 2002 include structural changes to improve occupant protection in frontal crashes. (Note: Information about when a specific vehicle was manufactured is on the certification label typically affixed to the car on or near the driver door.)

The Insurance Institute for Highway Safety has evaluated the crashworthiness of a 2002 A4 with the structural changes in a 40 mph frontal offset crash test into a deformable barrier.

The frontal offset crash test ratings also apply to the station wagon version of the A4, known as the A4 Avant, beginning with 2002 models manufactured after February 2002.

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 well.

Smeared greasepaint indicates where the dummy's head hit the roof rail during rebound. Head acceleration from this hit was low.

Intrusion into the driver's space was minimal, and all leg and foot injury measures were low.

Side

Rating applies to 2005-08 models built after October 2004

Tested vehicle: 2005 Audi A4 2.0T quattro 4-door 4wd with standard front and rear head curtain airbags and standard front seat-mounted torso airbags

The Audi A4 was redesigned for the 2002 model year. The car was reengineered and restyled during the 2005 model year so that 2005 models manufactured after October 2004 include structural changes to improve occupant protection in side impact crashes. Occupant protection in frontal crashes was not affected for 2002 and later A4 models manufactured after February 2002. (Note: Information about when a specific vehicle was manufactured is on the certification label typically affixed to the car on or near the driver door. The reengineered A4 can also be identified by a much larger grille compared with the earlier version.)

The side impact crash test ratings also apply to the station wagon version of the A4, known as the A4 Avant, beginning with 2005 models manufactured after October 2004.
