Moderate overlap front: original test

Rating applies to 2010-14 models

Tested vehicle: 2010 Subaru Legacy 4-door 4wd

The Subaru Legacy was redesigned for the 2010 model year. Frontal ratings are assigned by the Institute based on a test conducted by Subaru as part of frontal crash test verification.

The moderate overlap frontal crash test ratings also apply to the station wagon version of the Legacy, known as the Outback, also redesigned for 2010.
