The Chevrolet TrailBlazer was introduced in the 2002 model year as a larger, heavier replacement for the Blazer, which remained in production through the 2004 model year. Similarly, the GMC Envoy and Oldsmobile Bravada were redesigned for 2002, replacing entirely their earlier, smaller versions.

Structural, seat belt, and frontal airbag changes were made beginning with 2005 models to improve occupant protection in frontal crashes. Therefore, the frontal offset ratings for 2002-04 models do not carry over to 2005 and later models.
