Rally car driver and DC co-founder Ken Block has created the Trax STI, the world’s fastest tracked car. Based on the body of Block’s Subaru WRX STI, the suspension has been completely rebuilt for use in snow, with snow cat tracks replacing the wheels. Block’s excited about the Trax, because he says it “combines a two of my favorite things in life: driving a rally car in the snow and snowboarding in the powder in the backcountry.”
