NASCAR announced that the Nextel Cup cars will be required to use 13-gallon fuel cells at Las Vegas, instead of the 17 gallon tank that is to be used for the rest of the tracks this season. Also the tire that was used in Las Vegas testing in January will be changed. The reason: the new track surface and configuration at Las Vegas Motor Speedway. There were many accidents and the speeds were much higher. NASCAR did the same thing a couple years ago when Lowe’s Motor Speedway levitated then resurfaced the track.(2-11-2007) UPDATE: NASCAR will use a smaller fuel cell and a different tire compound for the Nextel Cup and Busch races at Las Vegas Motor Speedway March 10-11. “We decided to go with a 13-gallon fuel tank for Las Vegas,” said Pemberton. “We discussed it with Goodyear and felt we have the potential for some of the same issues we had at the Charlotte track last year.” The fuel cell this season for most races is 17.5 gallons. Using a smaller fuel cell will cause the teams to pit at shorter intervals, enabling crew members to check tire wear and make changes frequently, if needed. NASCAR officials were concerned with tire wear last year at Lowe’s Motor Speedway after the surface was repaved, which added additional grip. The Las Vegas track was completely rebuilt in the offseason, adding increased banking to the new surface. Cup teams tested at the 1.5-mile two weeks ago and the Busch teams were there last week. Some drivers complained about the speeds the cars were reaching on the new asphalt, along with the hardness of the tires. “Goodyear has decided to change the left-side compound [at Las Vegas] and maybe a construction that is different from the tests,” Pemberton said. “As we go into the day and age with new pavement, the surface is a little too abrasive right off. We just need one race under our belts. We have to get a little time on the racetrack.” (ESPN.com) AND LVMS statement regarding smaller fuel cells for NASCAR Weekend: “NASCAR’s decision to use 13-gallon fuel cells for both the UAW-DaimlerChrysler 400 and Sam’s Town 300 will make for an even more exciting race,” said LVMS general manager Chris Powell. “With the increase in the banking from 12 to 20 degrees, there are a lot of unknowns including race set up and tire compounds the teams will face for both races. This decision should keep the racing tighter and give the teams more opportunities to measure tire wear.” “Plus, we moved the pit road 275 feet closer to the grandstands, so this will give all of the race fans even more opportunities to watch the excitement of the all-important pit stops.”(LVMS PR)(2-11-2007)
