Now in its fifth generation, Subaru has offered four-door sedan and five-door body variants since 1992; the firm also offered a coupe from 1995 until 2001, and a 5-door wagon from the Impreza’s introduction in the form of a hatchback. Mainstream versions have received “boxer” flat-four engines ranging from 1. 5- to 2. 5-liters, with the performance-oriented Impreza WRX and WRX STI models uprated with the addition of turbochargers. Since the third generation series, some markets have adopted the abbreviated Subaru WRX name for these high-performance variants. The first three generations of Impreza in North America were also available with an off-road appearance package called the Outback Sport. For the fourth generation, this appearance package was renamed the XV (Crosstrek in North America), and, unlike the Outback Sport (which was exclusive to the North American market), is sold internationally.
