Subaru Forester STI (Techically Forester tS)

The Forester STI SUV We’ve All Been Waiting for Is Finally Here… Sort of…

Christmas has come early this year for Subaru fans, more so for Subaru fans in Japan. For about a decade Subie aficionados everywhere have lamented the lack of STI treatment on any car in their line up other than the Impreza. Don’t get me wrong, I LOVE the WRX STI, especially the 2015 Subaru WRX STI I have sitting in the garage (that get’s it’s own long-term test report next month). But, admittedly it’s light years less practical than the bigger Subarus, like the Outback and the Forester, which are, in turn, even more light years less fun and scooty than the WRX and STI.


So, for pretty much that same decade of lament, more industrious Subaru owners, who are unsatisfied with the Forester’s erstwhile range-topping 250 horsepower and the lack of cavernous cargo space of the WRX and STI, have built home-made Franken-cars. These one-off Forester STIs used the engine and drive-line of an STI and the body of a Forester, combined with a few aftermarket parts.


It appears that Subaru has paid attention. Now, if you’re hoping for a flat-out, bonkers 305 hp, full-STI-itized Forester, you can stop reading right here. Subaru has dipped but their little to into the pool of insanity, testing the waters of a high-performance Forester by releasing the Subaru 2015 Forester tS for sale in Japan. “tS” technically stands for “Tuned by STI”. So, the 2015 Forester tS is more like a Forester WRX than a Forester STI. Which, is a good start.

So, what exactly did Subaru do to the puppy dog of their line-up to make it a Forester tS? The most obvious modifications need to be performance related, right? Each of the 300 planned examples of the Subaru Forester tS will be powered by Subie’s bulletproof turbocharged, 2.0-liter four-cylinder mated to a six-speed continuously variable transmission (CVT). However, the Forester STI… er tS, rather… will get some appropriate upgrades in the form of new software controlling the engine and gearbox and a new transmission cooler. No word on what this will mean in terms of actual power and performance. I’d put the Forester tS’ output somewhere in the neighborhood of the 268 hp of the current WRX.


In terms of looks and suspension, there have been mods-a-plenty. The suspension has been dropped 15 mm (0.6 inches) and is essentially built from the STI parts bin. The 2015 Subaru Forester tS also gets the WRX and STI’s “Sport Sharp” driving mode, sharpening the whole thing up. More aggressive looks, a unique interior, bigger 19-inch BBS forged wheels and four-pot front/two-pot rear Brembo brakes round out the upgrades.


As I mentioned above, Subaru will only be making 300 examples of the Subaru Forester tS (aka 2015 Subaru Forester STI), and all of them will be going to Japan. Hopefully this thing will eventually makes its way across the Pacific. Price in Japan pre-tax is 4,027,778 Yen or about $33,868.
