About the original moderate overlap front test

Tested vehicle: 2006 Lexus GS 300 4-door with standard front and rear head curtain airbags and standard front seat-mounted torso airbags
Rating applies to 2006-11 models built after August 2005

The Lexus GS was redesigned for the 2006 model year. Beginning with 2006 models manufactured after August 2005, changes were made to the front seat-mounted torso airbags to ensure better abdomen coverage in side impact 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 tested car was manufactured after the side torso airbags had been modified.
