The NASCAR Sprint Cup Series teams of  Jeff Burton, Tony Stewart, Matt Kenseth, Kasey Kahne and Travis Kvapil have concluded a two-day test session at Las Vegas Motor Speedway to help determine which Goodyear tire will be used in the 2008 UAW-Dodge 400 on March 2, 2008.

Jeff Burton has been testing tires on the NASCAR Car of Tomorrow at LVMS for Richard Childress Racing.

"It's a lot to learn," began Burton, who was driving No. 29 Childress Chevrolets of teammate Kevin Harvick. "A lot of things are different, obviously, with the car.  It's quite a bit different animal, but all in all, I think it's going pretty well. The speeds are faster than I thought they would be.  When you factor in (the fact that) the track's a year older and those kind of things, the speed's quite a bit quicker than I thought it would be.  All in all, it's pretty positive."

Burton also spoke at length about the Car of Tomorrow, which will be utilized at all NASCAR Sprint Cup Series tracks in 2008.

"There are certainly different challenges.  The more we know about the cars, the more we learn about the cars, the better opportunity we have to be successful with them - or to be more comfortable with them. Somebody's going to be successful with them no matter what.  Becoming more comfortable with them is the hard part.  They are definitely different than the old car.  There are days I think it's no big deal and there's other days I think it's drastic.  What really matters is how you are (compared to) your competition.  When you can be competitive and run well, you feel pretty good about it.  When you don't, then obviously you point your finger at the Car of Tomorrow and blame everything on that.  You can't (compare) this car - how it drives - to the old car, because they are completely different.  I think a lot of the people that complain about the car because they're comparing it to the old car.  It's not the same car, so they're not going to drive the same.  The aerodynamics are hugely different. You don't have as much downforce and sideforce as you did in the past."  

Race fans are invited to attend NASCAR Preseason Thunder for all NASCAR Sprint Cup teams at LVMS on Jan. 28-29.  The speedway also will allow race fans access to the Neon Garage during testing.  NASCAR Nationwide Series teams will test at LVMS on Jan. 30-31.

Tickets for both the UAW-Dodge 400 and Sam's Town 300 NASCAR Nationwide (formerly Busch) Series event are on sale now by calling the speedway's box office at 1-800-644-4444 or online at Neon Garage, Lucky 7 parking and Driver Introduction passes also are available.

Report from Day 1 of Goodyear/COT testing:

Several NASCAR Sprint Cup Series teams are testing tires today and tomorrow for Goodyear at Las Vegas Motor Speedway.

Two-time NASCAR Sprint Cup champion Tony Stewart, 2003 champion Matt Kenseth, Jeff Burton, Kasey Kahne and Travis Kvapil are taking part in the two-day test session to help determine which tire will be used in the 2008 UAW-Dodge 400 at LVMS on March 2, 2008.

NASCAR's Car of Tomorrow (COT) will be utilized at all NASCAR Sprint Cup Series tracks in 2008. The tire test is important since the COT - which has never been raced at LVMS - and its numerous design changes present new handling and aerodynamic challenges.

Kasey Kahne, driver of the No. 9 Dodge for Evernham Motorsports, thought the first day of tire testing with the COT at LVMS went well.

"Actually, it felt pretty good," said Kahne, at the end of the sunny afternoon. "We tried a lot of different Goodyear tires and that's the main goal - to find something that will be really raceable when we come back in March. I think we made some gains on that. We're gonna do some more (testing) tomorrow. We'll see what happens. The COT seemed like it handled pretty good here. I think it's gonna be a good race when we come back here. I'm looking forward to it as long as we get the right tires."

Kasey was asked how the new COT compared to the "old" car he raced on the high banks here last March.

"There's definitely a difference. The more you drive it, the more you get used to it and kinda forget about the old car," said Kahne. "It's much different. It's kinda like taking a step back. From where we were with the old car to where we were with this one and now the more we work on this car the closer we're getting it back to where it needs to be. As time goes on, it'll be more advanced than the other car. It takes time, but it's getting better every time we get to practice with it."
