We were really excited when we started reading Subaru’s latest SEMA press release, as it listed things like a 400-hp WRX STI, the word’s “rally-prepped” and “Ken Block.” That was all well and good, but entirely too normal for a SEMA show car. And that’s what we discovered upon continued reading as we downloaded the solitary photo from Subaru’s media site. Yikes!

Along with all that good stuff, is a truly SEMA-rific TRAX system, provided by Mattracks, which replaces the car’s tires for some even more serious off-roading.

The car was built by Subaru Rally Team USA’s technical partner, Vermont SportsCar, and features a stripped down shell, roll cage, carbon fiber door panels and carbon/Kevlar Recaro racing seats with a HANS device. It makes 400-hp and 400 ft-lbs of torque and uses a KAPS 5-seed gearbox.

Even sillier than the TRAX system is the fact that the car comes with its own sleigh.

Subaru says the WRX STI TRAX is just in time for the holidays. We’re pretty sure this monstrosity just officially marked the start of SEMA.

Subaru Showcases the Ultimate Snow-Ready Performance Car at 2009 SEMA Show
Just in Time for the Holidays, a 400-Horse (-powered) Sleigh

CHERRY HILL, N.J., Nov. 2 /PRNewswire/ — 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.

With the exception of the Mattracks rubber track system, the car is rally-prepared and similar in specification Block’s #43 SRT USA competition STI. Starting with a stock 2009 Subaru Impreza WRX STI, Vermont SportsCar stripped the car’s interior bare, lightened the shell and then fully seam-welded it for added strength, also installing a multipoint roll cage manufactured from T45 steel. Major differences from the stock STI include the addition of lightweight carbon/Kevlar RECARO SPA ProRacer competition seats with the Head and Neck Restraint System (HANS), carbon fiber door panels and an onboard fire suppression system.

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.

And Now for Something Completely Different

The WRX STI TRAX can bring four more friends along for the fun with its one-of-a-kind custom sleigh. Constructed with hand-laid fiberglass using sandwich-core construction, the sleigh runs on custom built steel skis with torsion bar suspension. Yakima FatCat 4 snowboard racks carry Qty 2 DC XFB Snowboards.

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.
