AVONDALE, Ariz. -- One of the greatest combinations in NASCAR Sprint Cup history will come to an end this weekend when Tony Stewart competes in his final race for Joe Gibbs Racing at Homestead-Miami Speedway.

After the checkered flag falls, Stewart will move on to become owner/driver at Stewart Haas Racing, where he will field a two-car effort that also includes Ryan Newman. Stewart will be replaced in the No. 20 Home Depot Toyota by 18-year-old Joey Logano, who, despite rumors that the team is having second thoughts about moving him up to the Cup Series, has been given the seal of approval by Stewart.

"It's something new, and a group of guys that don't normally work together on a Cup car," Stewart said. "That's a team that Gibbs has had to put together to try to get Joey [Logano] some seat time for next year. I'm glad they've done that. They haven't seen the results that they want, but we all know that Joey is better than that, and once he gets in the 20 car, that will remedy itself."

While JGR will move on without Stewart, the driver is in the process of building his team for next season. He believes that recent cutbacks and layoffs on other teams have allowed him to hire some qualified people.

"You hire people off their work ethic and passion," Stewart said. "It's not so much on how they work with me, but rather how they work with each other. They only have to deal with me for a few hours a day; they are the ones that are together from 6 in the morning until 6 in the evening.

"The reason we have so many people applying for positions with our new team is because they understand our passion and desire to be successful. Nobody has blinders in the garage area. Everything that has happened they have seen."

Many in the garage think it's going to be unusual to see someone other than Stewart behind the wheel of the No. 20. "Yeah, there are going to be changes like that over the years," Jeff Gordon said. "It's just like Mark Martin not being in the No. 6 car. It always takes some time to adjust to it, but I think that it's exciting to see Joey Logano coming into the sport. He is a great talent. At the same time, I think it's really exciting to see Tony making a big move. I think seeing him in a different car is what's going to really be unique."

Chevrolet Clinches Manufacturers' Cup

Jimmie Johnson's victory, the seventh of the season for the Hendrick Motorsports driver, clinched the 32nd Manufacturers' Cup for Chevrolet in NSCS competition. With the way the American automotive industry is suffering during the economic downturn, at least General Motors has the manufacturer's title to brag about.
