TRD TUNDRA OFF-ROAD CONCEPT The TRD Tundra Double Cab 4x4 Off-Road Concept starts with a 6.5-foot bed. It combines an extensive list of custom features designed to showcase new TRD products on a rugged heavy-duty off-road truck that can be used to pull a large car-hauler trailer. The 5.7-liter V8 engine has been upgraded with the new TRD supercharger system that incorporates an air-to-liquid intercooler that boosts output to approximately 500 horsepower and is 50-state emission legal. The truck uses TRD 17x8 forged off-road wheels with 37x12.50 R17/D BFG tires on special front and rear wide-track long-travel suspensions. The body has been aggressively restyled with new front and rear fascias and five-inch wider fender sides. A custom trailer hitch has been incorporated into the bed. The 28-foot custom Featherlite car-hauler trailer was designed and built to resemble a working race car trailer, but is actually a traveling TRD product display featuring many new TRD products. Inside the trailer, visitors can get a look at the internal workings of the latest TRD superchargers and limited-slip differentials, see the latest wheel offerings or view a video of the actual design and construction of the TRD Off-Road Concept Tundra.
