We've grown quite fond of our long-term 2010 Subaru Legacy 2.5GT over the past few months, but we can't help but be somewhat jealous of the STI-tuned Legacy that's just been released in Japan. Subaru's in-house tuning department has laid hands on the new-for-2010 Legacy sedan (and the not-for-U.S. wagon!) to create the B4 2.5GT tS, which features a host of cosmetic and dynamic enhancements, even though the turbocharged 2.5-liter boxer remains unchanged.
Visually, the tS (which stands for "Tuned by STI") gets a new front lip spoiler, as well as a subtle deckled spoiler out back (fixed to the roof on wagon models). New 18-inch alloys wrapped in 225/45-series rubber sit at the corners and appropriate badging is applied all around. Inside, there's a revised instrument cluster, sport seats, carbon trim, a leather-wrapped STI steering wheel and, of course, STI branding on the shifter and floor mats.
Where the tS gets good, however, is in its performance upgrades, which include a sport exhaust system, a more robust Bilstein suspension, and new strut tower bars. Because the turbocharged flat-four keeps its stock output - 265 horsepower and 258 pound-feet of torque - this hotted-up Legacy won't be any quicker on the street. The other tweaks should make it even more poised during sporty driving, though.
While this may seem like just another juicy piece of Forbidden Fruit, we're sure that STI has upgrades for the U.S.-spec Legacy in the pipeline. (Please!) Scroll through the gallery below to see the Legacy tS's upgrades in detail.
