Moderate overlap front: original test

Rating applies to 2003-10 models built after May 2003

Tested vehicle: 2003 Lincoln Town Car Premium Signature 4-door

The Lincoln Town Car, Ford Crown Victoria, and Mercury Grand Marquis were re-engineered for the 2003 model year. Beginning with 2008 models, the Ford Crown Victoria was sold when new only to fleets. The Mercury Grand Marquis was discontinued after the 2010 model year.

The Insurance Institute for Highway Safety has evaluated the crashworthiness of a 2003 Town Car in two 40 mph frontal offset crash tests into deformable barriers. In the first test, a high acceleration occurred when the dummy's head rebounded against the B-pillar, indicating a possibility of head injury. This led Lincoln to modify the frontal airbag deployment characteristics on models produced after May 2003 (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 Institute tested a second Town Car with the modified airbags, and all head injury measures were low. Ratings of the Town Car listed here are from the second test.

Driver restraints and dummy kinematics
Dummy movement was reasonably well controlled in the second test. During rebound, the top of the head hit the roof rail and adjacent window frame between the A- and B-pillars. As in the first test, the driver's seat tipped toward the door.

Action shot taken during the second of two frontal offset crash tests.

The dummy's position in relation to the steering wheel and instrument panel after both crash tests indicates that the driver's survival space was maintained well (second test shown).

Smeared red greasepaint indicates where the dummy's head hit the B-pillar during rebound in the first test, producing a high head acceleration.

Forces on the lower left leg were high enough to indicate the possibility of injury in both tests (second test shown).

Tested vehicle: 2006 Ford Crown Victoria 4-door without optional side airbags

The Ford Crown Victoria and Mercury Grand Marquis were re-engineered for the 2003 model year.

Two tests of the Crown Victoria were conducted, one a 2007 model equipped with optional side airbags, and one a 2006 model without side airbags. These vehicles are rated separately, except that the structural ratings and rear passenger injury and head protection ratings for both vehicles are based on both tests. Beginning with 2009 models, side airbags were made standard.

Rear passenger head protection
The dummy's head was hit by the pillar behind the rear passenger door. This pillar is required by federal standard to provide some protection for occupants' heads.
