The 400bhp TRAX was built by Subaru Rally Team USA's technical partner, Vermont SportsCar from a rally-prepared 2009 WRX ST. EXE-TC Group N competition rally dampers were added, the drivetrain lowered three inches and the wheels tossed in favor of a Mattracks rubber track system.
Driving what must challenge for the title of world's fastest snowmobile is a 2.5-liter, 4-cylinder, turbocharged, intercooled STI engine that puts out around 400 horses and 400 lb.-ft. of torque. This is married to a KAPS 5-speed close-ratio dog-engagement gearbox and the Subaru programmable DCCD (Driver Controlled Center Differential) all-wheel drive system.
So you've got something to do in the back country, the TRAX STI also has a specially designed sleigh which can drag four people and their snowboarding gear up the slopes.
