The Subaru Legacy has been given numerous tweaks for 2013, resulting in a more complete package. The major mechanical difference is a new generation of 4-cylinder engines, resulting in more power and better fuel economy, but suspension settings have also been revised and the available CVT transmission is improved from last years model. The styling of the car is also changed. New front headlights compliment a new grill and front bumper which combine to give the car a sportier look.

More options are available to buyers, the most important of which is the EyeSight driver assistance system. EyeSight integrates adaptive cruise control, pre-collision braking and vehicle lane departure warning into one package.

Trim levels have been significantly simplified for 2013. Subaru now offers three basic trim models, Base, Premium and Limited, meaning that the 2.5GT is no longer offered in 2013 and that Subaru has cut the turbocharged engine out of the lineup entirely.
