Redwood Rally Forge takes the 2006 Scion xB’s upright, city-box silhouette and stretches it into an alternate-universe WRC weapon—wide, tall, and built to survive long, fast gravel stages without losing the instant recognition that makes the xB such a cult platform. The track is pushed out hard (190mm front, 210mm rear) with trapezoidal flares that do more than cover tire: vertical lips kick debris away, and the concave crown guides dirty airflow into side cooling ducts behind the front wheels.
Under the matte forest green and sand-pearl dusting is a believable endurance rally package: long-travel suspension, real skid protection, and aero meant for stability in turbulent, dusty air rather than showroom drama. A composite hood with a proper ram-air feed and extraction vents manages underhood temps, while the roof scoop supports cabin air and systems cooling. Out back, the tall multi-element wing and functional diffuser vent work with the extended hatch to keep the brick planted when the road turns to marbles.
