NASCAR Preseason Thunder Las Vegas is complete, and it's no surprise that a Roush Racing driver is setting the pace. Carl Edwards, driver of the No. 99 Office Depot Ford, was fastest during Wednesday's morning session with a lap of 170.778 miles per hour. That time also was the fastest among the 48 Nextel Cup cars that tested during the three-day test session at Las Vegas Motor Speedway. "Testing was great," said Edwards. "We were really fast and I'm pretty pumped to come back here and race. I love this race track and it's a lot of fun. If I don't run into anything and we keep the body in one piece we should be alright." Edwards is looking to become the fourth different Roush driver to win the UAW-DaimlerChrysler 400 and to secure car owner Jack Roush's sixth win at LVMS. Kasey Kahne was second (170.374 mph) on the speed chart Wednesday, followed by Las Vegan Kurt Busch (169.353 mph), Ryan Newman (169.099 mph) and Matt Kenseth (169.056 mph). Newman's No. 12 ALLTEL Dodge was the first car on the track today but within five minutes had brushed the wall and had to pull into the garage. Busch was fastest during the afternoon session with a lap of 169.694 mph. Busch, Dave Blaney and Travis Kvapil all spun during the afternoon session, but no one made contact.
