Moderate overlap front: original test

Rating applies to 2004-08 models

Tested vehicle: 2004 Acura TL 4-door

The Acura TL was redesigned for the 2004 model year. Its base price has increased sufficiently to reclassify it as a midsize luxury car. (The 1999-2003 TL was classified as a midsize moderately priced car.)

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.

Dummy movement was well controlled. 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 forces on the legs and feet were low.

View of the vehicle after the crash with doors removed, showing the side airbags and damage to the occupant compartment.

Action shot taken during the side impact crash test showing the driver dummy's head was protected from being hit by hard structures by the side curtain airbag.

Smeared greasepaint shows where the rear passenger dummy's head was protected by the side airbag.
