The new model will be a conventional five-door hatchback, rather than the more conventional four-door saloon and estate variants we've come to know, and was previewed by the B5 TPH concept which appeared at the last Tokyo auto show (see gallery). However, Subaru isn't breaking with tradition under the bonnet; the new Impreza will be powered by a choice of naturally-aspirated 1.5- and 2.0-litre petrol 'flat-four' boxer engines to begin with.
The iconic turbocharged Impreza STi will come later. It will feature body styling even more extravagant to the current car, and is likely to be powered by an evolution of the 2.5-litre engine Subaru currently offers, but we won't get to see it until 2008. There are no plans to carry over the intermediate WRX model.
