TOKYO —Fuji Heavy Industries formally rolled out its redesigned Subaru Impreza hatchback this week. The new Impreza goes on sale in Japan today and will be available in U.S. showrooms in August.

Fuji showed off three model variations: the base Impreza 15S, which gets a 1.5-liter engine; a midrange Impreza 20S with a 2.0-liter engine; and the Impreza S-GT with a 2.0-liter turbo engine. Reuters reported that Subaru's first diesel engine will most likely make its debut in Europe early next year. Fuji is still negotiating with Toyota over whether Subaru will offer a gas-electric hybrid variant.

Details on the redesign include a shortened rear overhang, a new double-wishbone rear suspension and, in the cabin, a driver seat lifter and tilt steering. Fuji said the low center of gravity of the Boxer engine has been enhanced by mounting the engine 0.9 inch lower on the chassis to improve stability. Side airbags and side curtain airbags are optional. Stability control is an option on the S-GT models.
