Jimmie Johnson, coming off his victory Sunday in the Allstate 400 at the Brickyard, has added two races to his 2008 schedule.

In addition to his duties behind the wheel of the No. 48 Hendrick Motorsports Chevrolet, Johnson, a two-time reigning Sprint Cup champion, will make his Truck Series debut Aug. 20 in Bristol -- driving for NFL star Randy Moss. Johnson will drive the No. 81 Kobalt Tools Silverado fielded by Randy Moss Motorsports.

Johnson also will drive the No. 48 Lowe's Chevrolet fielded by Dale Earnhardt Jr.'s JR Motorsports in the Nationwide Series race Aug. 9 at Watkins Glen.

In Nationwide, Johnson has made 88 starts, with his only victory in 2001 -- his second and final full season in the former Busch Series -- at Chicagoland.

"Watkins Glen and Bristol are two tracks where I really want a win," Johnson said. "I enjoy racing [on the road course] at Watkins Glen and, for some reason always seem to be a little better there than Sonoma. We've had some top fives, so, hopefully, this will put us in the win column.

"As for the trucks, I am really looking forward to that. I have never run a truck race, so it should be fun. Heck, my brother Jarit has run more than me. But it's going to be a good time."

Formula One

Lewis Hamilton is seeking his third consecutive victory this season at the Hungarian Grand Prix in Budapest, while main rival Ferrari hopes rebound from disappointing results.

Hamilton made two dramatic passes to win the German Grand Prix July 20 to take a four-point lead in the overall standings over Ferrari's Felipe Massa.

Hamilton, 23, who could be the first British driver to win three in a row since Damon Hill 12 years ago, won't make any strategic changes going into the 11th of 18 races.

"The last couple of races the car has been the best it has ever been. I'd like to continue with the momentum I have, for sure," Hamilton said. "The car's the best it's been this year. [So] it would be nice to score points this weekend, and that's our aim."

With the 2.722-mile Hungaroring track bearing a resemblance to Montreal and Monte Carlo with its twisty turns and tight corners -- 14 in all -- Hamilton knows qualifying will be crucial.

"It will be hot and tiring, too, so keeping your focus and concentration will be vital," said Hamilton, who won at Monaco and led in Canada before a pit lane accident led to an early retirement.

Coming off a demoralizing German GP marked by car problems, the Italians need to sway momentum away from its principal rival. It won't be easy; its British rival has won two of the past three races in Hungary.

McLaren has cut Ferrari's lead in the constructors' standings to 19 points, while Kimi Raikkonen has slipped seven back of Hamilton.

Raikkonen, who won in Hungary with McLaren three years ago, can count on a large Finnish contingent to boost his morale following a dismal run since his previous victory at Barcelona.

The motivation "doesn't disappear," defending world champion Raikkonen said. "It's not nice when it's not going so well but it's not the first time."

In other F1 news, Heikki Kovalainen will remain a McLaren driver for the 2009 Formula One season.

Kovalainen, 26 of Finland, who is sixth in the standings in his first season with the British team, was confirmed as a driver for next year by McLaren.
