Martinsville is the only track at which NASCAR teams run this left-side tire code (D-4588) . . . this right-side tire code (D-4590) was run on all four tire positions by NASCAR teams on all road courses in 2013 . . . as on most NASCAR ovals one mile or less in length, teams will not run inner liners in their tires at Martinsville.
NASCAR Unveils Air Titan 2.0:
NASCAR introduced an evolution in innovation - the results of which will continue to elevate a fan’s race-viewing experience to an even greater level. The Toyota-hauled next generation of Air Titan, the cutting-edge track-drying technology, made its race weekend debut at Martinsville Speedway today.
Air Titan 2.0 is a more compact, more nimble and more environmentally friendly version of its innovative predecessor - one that since its introduction in February 2013 has rescued multiple races, including this year’s Daytona 500. Air Titan 2.0 signals a major step forward in NASCAR’s innovation cycle.
It replaces the bulky support vehicles required by Air Titan 1.0 with a single, self-contained unit that’s perched on the bed of a Toyota Tundra. By addressing the size of the power source, NASCAR now has the ability to deploy up to 21 units in Toyota Tundras at larger venues and operate more efficiently on smaller tracks.
The Air Titan 2.0 more than triples the blade capacity of the original version and deliver 2.6 times more air volume at a speed of 568 mph, while raising the air temperature by 70 degrees over ambient.
With the combination of water removal and accelerated evaporation, the ultimate goal is to reduce track-drying time by 80 percent. Air Titan 2.0 will consume nearly 80 percent less fuel and emit 80 percent less carbon dioxides. Air Titan 2.0 works in conjunction with the Eco-Infused Elgin Track Vacuum/Sweeper and existing jet dryers. In coordination with the roll out of the Air Titan 2.0, Elgin has now become the Official Sweeper of NASCAR Green.(NASCAR)(3-29-2014)
