2003 Toyota Corolla

Tested vehicle: 2003 Toyota Corolla LE 4-door
Rating applies to 2003-08 models built after December 2002

The Toyota Corolla was redesigned for the 2003 model year.

The Insurance Institute for Highway Safety has evaluated the crashworthiness of the Corolla in two 40 mph frontal offset crash tests into deformable barriers. In the first test, forces on the right tibia were high enough to indicate the possibility of lower leg injury. This led Toyota to modify a portion of the padding underneath the carpeting on models produced after December, 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 Institute tested a second Corolla that had been retrofitted with the improved padding, and forces on the lower right leg were reduced so that significant injury was unlikely.

About the original moderate overlap front test

Tested vehicle: 2005 Toyota Corolla LE 4-door without optional side airbags
Rating applies to 2003-08 models

The Toyota Corolla was redesigned for the 2003 model year. Side curtain airbags designed to protect front and rear occupants’ heads became optional beginning with 2005 models, in addition to the optional side airbags designed to protect drivers’ and front passengers’ torsos available since 2003.

Two tests of a Corolla were conducted, one with optional side airbags for the driver and rear passenger, and one without. These vehicles are rated separately, except that the structural ratings for both vehicles are based on both tests.
