2010 Toyota Tacoma X-Runner RTR Concept
The Tacoma X-Runner RTR (Ready to Race) project pickup truck, which will make its public debut at the 2010 SEMA Show, is an exercise in demonstrating Toyota's engineering prowess by creating an in-house, high performance vehicle through the utilization of Toyota parts. As a result, the Tacoma RTR is a "parts bin" build with all but a few components currently available on Toyota products (traction bars and drive-line shaft are the only two non-Toyota parts).

The Tacoma X-Runner RTR achieves its performance credentials by dropping in a
completely stock, current-generation Tundra 5.7-liter V8 engine into the
unmodified engine bay along with a six-speed automatic transmission. A Toyota
Racing Development (TRD) Supercharger Kit was added, bringing the SAE certified
power stats to 504 horsepower and 550 lb-ft of torque. The truck runs on
premium gas rather than race fuel.
A stock Tundra rear axle, with a 4.3
ratio and 10.5-inch ring gear, was narrowed a total of 5.7 inches to Tacoma
rear-track width). A TRD prototype mechanical limited slip differential,
designed by Eaton, was added to maximize traction. The truck rides on current
generation Tacoma 15-inch styled steel wheels that were modified to 10-inches
wide in the rear and wrapped by 30x11.5x15-inch Goodyear Eagle Dragway Specials.
The front wheels are 4.5-inches wide and mounted to 28x4.5x15-inch Goodyear
Eagle Front Runners.
The Tacoma X-Runner RTR was lowered approximately
4.5 inches from stock X-Runner height, and a custom exhaust system was
fabricated to include two TRD perforated-chamber mufflers with a 3.5-inch pipe.
The only body modification to the X-Runner RTR was the relocation of the exhaust
outlet from behind the passenger-side rear wheel to underneath the cab to help
maximize rear-suspension compression, which is common in hard launches. The
brakes were left untouched from the stock Tacoma X-Runner braking system, and
vehicle traction aids are still functional, including ABS, Vehicle Stability
Control and traction control.
The exterior body panels of the Tacoma
X-Runner remain untouched. A silver and red paint scheme applied by Five-Axis
was inspired by classic low cost but ready-to-race sports cars, including the
late 1960s Dan Gurney Cougar XR7-G. The number "95" on the doors signifies the
first model year the Tacoma nameplate was sold in the U.S. The Tundra i-Force
engine badge was painted on the front fenders to signify the upgraded power
plant and is in the same location it would be found on the current Tundra. In
classic hot rod style, the hood is adorned with "504 HP" graphics signifying the
SAE verified horsepower. Also on the hood, and unique to this build, is a TRD
Supercharger graphic featuring a tornado, signifying the forced induction. The
side rocker panels feature the X-Runner logo.
