2015 Subaru WRX

Tested vehicle: 2015 Subaru WRX Premium 4-door 4wd
Rating applies to 2015-21 models

The Subaru WRX was redesigned for the 2015 model year. Although the car shares some of its design elements with the Subaru Impreza, there are now sufficient differences for the WRX to be rated separately.
