Take (insane) rally car racer Ken Block’s tricked out Subaru WRX STI, replace the tires with snow cat tracks, crank it up to 400 horsepower, and you’ve got the “ultimate backcountry shred car.” It’s called the TRAK STI and it was supposedly outed in a YouTube video earlier this year, then was officially announced this month along with the requisite official YouTube video of Block going nuts in the snow.
