Moderate overlap front: original test
Rating applies to 2008-11 models
Tested vehicle: 2008 Subaru Impreza 2.5i wagon 4wd
The Subaru Impreza was redesigned for the 2008 model year. Moderate overlap frontal ratings are assigned by the Institute based on a test conducted by Subaru. The moderate overlap ratings apply to both the 4-door sedan and 5-door (wagon) variants of the Impreza.
