We don't spend a lot of time talking about the Subaru Exiga, because this Japanese-style minivan probably won't ever come to the U.S. It's roomy enough all right (we sat in all three rows today) since it's based on the current Impreza/Legacy architecture, but the rear doors are all hinged and Subaru would rather sell us Tribecas.

Still, there are a couple of interesting specialty Exigas in its booth at the Tokyo Auto Show. The more eye-catching of the two in the Subaru Exiga 2.0GT Tuned by STI. You'll hear people call this the Exiga STI, but it's far less of an STI than the Forester XTI concept shown at last year's SEMA show.

It has zero engine modifications and uses the same 221-hp, 2.0-liter, turbocharged boxer four as the standard Exiga 2.0GT (the top trim in the range). It also has a five-speed automatic with shift paddles and downshift rev-matching like the U.S.-spec Legacy 3.6R.

The STI part of it comes from the fact that Subaru Tecnica International place on its own springs and dampers, along with a strut tower brace. The wheels are different, too, but still just 17s like the stock alloys. And obviously, there's a body kit and flashier exhaust tips. Although the show car is concept done up by STI for Tokyo, Subaru plans to place this Exiga into production — no surprise at all considering there's already a very similar version of the Japanese-spec Legacy 2.0GT wagon.

More worthy of your attention is the Exiga EyeSight technology exhibit, as it has an interesting new country system that will eventually make it to U.S.-market Subarus. More on this Exiga after the jump.

This Exiga's EyeSight system uses a pair of cameras mounted on either side of its rearview mirror in conjunction with a 3D image processor and radar-based adaptive cruise control.

It detects both pedestrians and vehicles that might potentially interfere with your intended trajectory — if you crash into them, you know. Not only can it warn you well in advance, it can automatically take corrective brake action to avert a collision if you're slow on the draw.

Lane departure warning will also be part of EyeSight.
