The next-generation Subaru Forester STI is expected to be formally revealed on November 25.

The Subaru Forester STI is back.

Or at least, that's the impression given by a new series of teaser images shown online overnight.

One of the original performance SUVs is expected to be officially reinstated on November 25, when Subaru will reportedly reveal the next-generation model based on its regular Forester XT.

The early teaser images reveal the STI will wear a tarted up exterior with flared guards, larger wheels and multi-caliper brakes. The hotted-up Forester will reportedly feature more aggressive aerodynamics and cooling, too.

Under the bonnet, it's expected the new model will bring a turbocharged four-cylinder engine closely related to that found in the 221kW WRX STI. All-wheel drive grip is a surety, however the overall power output is yet to be confirmed.

While the Forester STI was one of the very first performance SUVs, the new generation model will find itself in a competitive segment now featuring the likes of the Mercedes-Benz GLA45 AMG and Audi RSQ3.

The next-generation Subaru Forester STI is expected to be formally revealed on November 25.

It is yet to be confirmed whether the Forester STI will be available locally as Subaru Australia has been contacted for comment.
