About the original moderate overlap front test

Side: original test

Rating applies to 2013-20 models

Tested vehicle: 2013 Lexus GS 350 Premium 4-door with standard front and rear head curtain airbags and standard front and rear seat-mounted torso airbags

The Lexus GS was redesigned for the 2013 model year. Side ratings are assigned by the Institute based on a test conducted by Toyota.

Rear passenger head protection
The dummy's head pushed past the side curtain airbag and was hit by the window sill of the passenger door. This impact did not produce high head injury measures, but the head protection is inadequate.
