The Toyota Tundra TR is a one-off drag truck that could join the ranks of the Ford Lightning, Dodge Ram SRT-10 and Chevrolet SS 454 if put into production.

At this year's SEMA show, it seems like there's a Toyota Tundra concept truck to answer every trucking question that Ford, Chevrolet and Dodge have ever posed. The TR Concept addresses the issue raised by trucks like the Ford Lightning, Dodge Ram SRT-10 and Chevrolet SS454: what is the best way to get a pickup truck down the quarter-mile as quickly as possible?
The Tundra TR is outfitted to be a drag-racing "sleeper," thanks to an exterior that's notable for its almost complete lack of adornment. 18-inch steel wheels and blacked-out trim front and rear give it a menacing, purposeful look.
Starting with the lightest Tundra in the lineup, the regular cab, short-bed model, this 4x2, 5.7 liter V8-equipped show truck has been outfitted with a "Thunder Pak," which consists of a TRD lowered suspension and ceramic-coated black exhaust, as well as a supercharger. Just in case that's not enough to squirt it past the other drag trucks, the Tundra TR can also bring 150-horsepower shots of nitrous to the table.
