Subaru released a second teaser image of the upcoming WRX STI 209, which is set to debut at the Detroit Auto Show (NAIAS) on January 14.

This will mark the first time Subaru will offer one of its ‘S20x’ special editions outside of its home market in Japan and will most likely be marketed as the swan song of the current generation.

The new Subaru WRX STI S209 will be offered in limited numbers, although the Japanese company hasn’t revealed yet the exact number of cars.

The new teaser image confirms some of the changes we noticed on Subaru’s video teaser last December over the standard STI. These include a revised aero agenda that features a proper big rear wing that’s probably lifted from the Type RA, as well as a pair of dive planes on the sides of the front bumper.

Subaru’s last special STI model, the Japan exclusive S208, was powered by a turbocharged 2.0-liter flat-four with 325hp. In the US however, the STI is bound to the 2.5-liter boxer engine which makes 305hp as standard and 310hp in the Type RA.

We sincerely hope that the S209 will add a few more ponies into the mix in order for the current-generation Scooby to go out with a bang. Fingers crossed.
