Subaru today announced two tuner models along with one of the automaker’s classics, which are all set to debut at next week’s 2009 SEMA Auto Show in Las Vegas.

Working closely with its own in-house performance accessories line, Subaru Performance Tuning (SPT), Subaru has built a custom 2010 Impreza WRX STI and Legacy aimed at enthusiasts at two different ends of the aftermarket spectrum.

The WRX STI by SPT demonstrates what a WRX STI owner can build at home using just the SPT catalog as a source for bolt-on parts. The concept vehicle offers more power along with even sharper handling response, aiming it squarely at performance enthusiasts looking for aftermarket upgrades.

The drivetrain in the WRX STI by SPT is essentially stock, which means a 2.5 liter turbocharged and intercooled four-cylinder ‘boxer’ engine. An SPT exhaust system, however, boosts output to 315 horsepower and 290 pound-feet of torque.

The 2010 Legacy VIP concept, on the other hand, is a one-of-a-kind vehicle inspired by the VIP rides found on the streets of Tokyo, Los Angeles and New York. VIP is a style known for a clean, yet heavily reworked, luxury theme with an emphasis on impossibly low ride height and huge, aggressively styled wheels.

To ride low, the Legacy VIP gets air suspension system from Universal Air. Subaru has also sourced a number of body parts from the Japanese domestic market (JDM) Legacy, including the hood, bumper faces, sport grille, front and rear under spoilers, HID headlights and fog lights.

The third vehicle announced for Subaru's SEMA display is also one-of-a-kind: A special SPT delivery van that promises to deliver go-fast parts very slowly. That's because it only has 25 horsepower.

The 1969 micro van (emphasis on "micro") was one of the first models sold by Subaru of America. Its two-cylinder, two-stroke engine musters 25.3 pound-feet of torque.
