The 400HP Subaru Impreza WRX STI TRAX with snowfall tracks will be unveiled at the 2009 SEMA Auto Show. Based on a revive-prepped 2009 WRX STI, the TRAX was built by Vermont SportsCar for SRT USA driver Ken Block. Despite the Mattracks rubber track system, the car is near duplicate to Block’s #43 SRT USA competition STI.

Vermont SportsCar started with a carry Impreza WRX STI and then gutted the interior, “faded the shell and then quite joint-welded it for added depth,” and installed a multipoint steel spin crate. After this was determined, the troupe added RECARO SPA ProRacer competition sport seats, carbon strand door panels, and an onboard fire suppression order. Other goodies contain a Yakima FatCat 4 Snowboard Rack, a Yakima Landing Pad rack support, and DC Shoes XFB-C Snowboards.

Power comes from a turbocharged 2.5-liter four-cylinder engine (with a MOTEC M800 ECU) that produces about 400 hp and 400 lb-ft of torque. Besides the enhanced engine, Vermont installed a KAPS five-hustle close-ratio ‘dog-engagement’ gearbox, a Subaru programmable DCCD (Driver Controlled Center Differential) all-turn oblige logic, custom machined hubs, and Group N competition recover dampers by EXE-TC.

The TRAX also comes with a custom carbon structure toboggan, which can accommodate four passengers. Riding on steel skis and a torsion bar suspension, the sleigh boasts heated leather RECARO seats, a naval-grade Alpine stereo system, LED lighting, and carbon integrity adorn.
