The defending race champion, a veteran with a new team and two of NASCAR's young guns are scheduled to take part in a two-day Goodyear tire test today and Thursday at Las Vegas Motor Speedway.

Carl Edwards, who won this year's NASCAR Sprint Cup event at LVMS, will be joined by Mark Martin, Brian Vickers and David Stremme for testing this week. For Martin, it will be a chance to get acquainted with Hendrick Motorsports' No. 5 Chevrolet, which he will pilot in the 2009 season. Vickers will be in the Red Bull Toyota, and Stremme will be in his new Penske Dodge. Stremme has replaced Ryan Newman in the No. 12 car for next season.

"These two days in Vegas are going to be, quite possibly, the two most important days of our 2009 season," said Alan Gustafson, crew chief for Martin. "With NASCAR's new ‘no testing' rule, we are very fortunate to have been invited by Goodyear to this test. This gives us two extra days on an intermediate track that only three other teams are getting. We need to maximize that time all we can."

The race teams and Goodyear will be testing in preparation for the March 1 Shelby 427 NASCAR Sprint Cup Series race.

The test will be closed to the public.
