But they're not full-on STI models, just a pair of styling packages. Boo, hiss.

Subaru has revealed the pair of hotted-up 'STI' concepts it's planning to reveal at the Tokyo Auto Salon next month, in the form of two sporty-styled specials.

The Impreza STI Concept takes the base hatch, and adds a set of custom wheels, some black add-ons to the front bumper and side skirts, central exhaust, and a contrast roof finish. Not exactly groundbreaking stuff, but similar to what we've seen from Mazda with its range of add-ons for the 3.

Inside, Subaru says there's a deep red finish on the leather with a unique texture, but there are no images to confirm what that will actually look like.

Under the bonnet, the car has been fitted with a heavily turbocharged... who are we kidding, it's based on the regular 2.0-litre Impreza offered in Japan, making the same 115kW and 196Nm of torque.

On the Forester front, the STI Concept is based on the e-Boxer hybrid powertrain. There's no extra grunt, meaning you get the company's 115kW, 2.0-litre direct-injection petrol engine with a CVT gearbox/motor unit and a lithium-ion battery pack under the cargo floor.

Externally, it's been treated to an ever more aggressive bodykit than the Impreza, offset by a custom grey paint finish, 19-inch alloy wheels, and six-piston front brakes.

At this point, there's no word on whether either model will make production, but a performance model has been put on the table by Subaru Australia.

"The XT was a fantastic car and we love it. It was great fun. It was quite unique in the market," Colin Christie, Subaru Australia boss told CarAdvice.

"I think the reality is, and Subaru's done the exact right thing, which is where the growth or the potential growth or the future growth of Forester is which is attracting a bigger audience, will come from the core car," he said.
