To say that Kasey Kahne has a lot riding on his test session at Las Vegas Motor Speedway in two weeks, would be an understatement. After winning the pole and finishing second in the 2004 UAW-DaimlerChrysler 400, Kahne posted a disappointing 38th and crashed in last year's event. But even before the crash, Kahne was not a contender in the event. "When we went (to Las Vegas) last year, we thought we were going to be pretty good," said Kahne. "When we left, I didn't think we were near as good as we had thought." Kahne will join more than 40 other NASCAR Nextel Cup Series drivers who will participate in NASCAR Preseason Thunder Las Vegas from Jan. 30-Feb. 1. The drivers will be preparing for the March 12 UAW-DaimlerChrysler 400. Kahne says that testing at LVMS is a stepping stone to understanding what changes need to be made for many other tracks. "It helps in preparation for other tracks because so many tracks are similar to Vegas," said Kahne, who is sponsored by the UAW-DaimlerChrysler National Training Center. "If you are good at Vegas, you can be good at a lot of places. If you're not good there, you're going to have problems at a lot of places." Kahne says that by the end of tests at LVMS, his team will better understand their chances at the UAW-DaimlerChrysler 400 in March. "When we leave Vegas, we'll know what we have as far as how the car will handle and how we stack up against the other teams," said Kahne. "It's a very important test for all the Nextel Cup teams." The public is invited to watch the test sessions free of charge each day from 9 a.m. to 5 p.m. Tickets for the March 10-12 NASCAR Weekend are available by calling 1-800-644-4444 or logging on to www.lvms.com.
