If you've ever visaged the prospect of driving through snow in a Subaru WRX STI with stock summer tires, you will really appreciate the TRAX STI. And you will also realize that Ken Block's chutzpah is bottomless. He'll try anything once. Now he's gone and place snowcat tracks on his STI rally car.

This is the preview video of a test run near his Utah mountain home. A longer, more death-defying video is undoubtedly in the works.

In addition to the special (and specially awesome at that) tracks, the TRAX has a fully reworked suspension (shocker) with Group N-type dampers prefabricated by the UK-based company EXE-TC, along with a version of the 2.5-liter turbo boxer four good for 400 hp — and, no doubt, a great deal of torque. The transmission is a 5-speed dog 'box.

Not shown here is the optional sleigh that hitches to the back of the TRAX STI and transports up to four snowboarders and their boards. Snowboarding, you'll be unsurprised to learn, is another of Block's passions.
