The Subaru WRX STI, when equipped with proper tires, is capable of impressive all-weather performance. But when even snow tires are not enough, Subaru offers a solution - a 400-hp WRX STI equipped with a snow tracks system, as showcased at the 2009 Specialty Equipment Manufacturers Association (SEMA) Show at the Las Vegas Convention Center, Nov. 3-6.
Starting with a rally-prepared 2009 WRX STI, Subaru Rally Team USA's technical partner, Vermont SportsCar, built the one-off 400-hp TRAX STI envisioned by, and built for, DC Shoes co-founder and SRT USA driver Ken Block. The WRX STI TRAX is ready for the half-pipe, with a Yakima FatCat 4 Snowboard Rack up top, a Yakima Landing Pad rack base and DC Shoes XFB-C Snowboards. Naturally, there is a custom matching sleigh to go with it.
Under the hood, the ultimate Subaru snow machine sports a 2.5-liter, 4-cylinder, turbocharged and intercooled STI engine tuned with a MoTeC M800 ECU. The engine, which kicks out approximately 400 hp and 400 lb.-ft. of torque, is teamed with a KAPS 5-speed close-ratio dog-engagement gearbox and the Subaru programmable DCCD (Driver Controlled Center Differential) all-wheel drive system. Employing custom machined hubs, the drivetrain - which has been dropped three inches - is mated to Mattracks 105M1-A1 rubber track conversion. The car also features Group N competition rally dampers made by EXE-TC.
Protected beneath the padded roll bars are four heated and embroidered leather RECARO Speed seats with Sabelt 4-point harnesses. For music on the slopes, a marine grade water resistant Alpine digital media receiver is coupled with marine grade Kicker speakers and a 10-inch subwoofer. The rear of the sleigh features a large cooler and a grab-bar for towing snowboarders. Cup holders and LED lighting finish off the interior.
The sleigh also features a carbon fiber dashboard, center tunnel cover and rear-cooler cover. Tucked into a glovebox within the carbon fiber covered dashboard are two Viosport POV.1 camera systems. One camera lens is flush-mounted within the dashboard to film passengers, and the other is mounted high on the roll bar to record action around the sleigh.
