Tested vehicle: 2009 Chevrolet Impala LT 4-door with standard front and rear head curtain airbags and standard front seat-mounted torso airbags
The Chevrolet Impala was redesigned for the 2006 model year. Beginning with 2009 models, side curtain airbags were made standard for retail and fleet buyers (they had been optional for fleet buyers previously), and side airbags to protect the drivers' and front passengers' torsos also became standard (the side torso airbags were not available before).
Two tests of the Impala were conducted, one by the Institute of a 2006 model equipped with side curtain airbags, and the other by General Motors of a 2009 model with both side curtain airbags and side torso airbags. These vehicles are rated separately, except that the structural ratings for both vehicles are based on both tests, as are rear dummy injury and head protection ratings, because no changes were made to the rear occupant compartment. Driver dummy injury and head protection ratings for the 2009 model are assigned by the Institute.
