The fourth generation of Subaru Impreza was introduced for the 2012 model year. The fourth generation Impreza was offered as a range of compact sedans and hatchbacks powered by a selection of naturally aspirated or turbocharged flat four engines. The fourth generation did not feature a performance variant as production of the Third Generation Impreza WRX continued until 2014. For 2015, the Subaru WRX became its own independent model, and thus does not feature in the fourth generation Impreza, which was produced until 2016 and replaced by the Fifth Generation Subaru Impreza.
