What's new in motor sports heading into this weekend:
1. It's a rare weekend off for NASCAR's Nextel Cup Series, which returns July 29 at Indianapolis Motor Speedway for one of its biggest races of the year, the Allstate 400 at the Brickyard.
But NASCAR's Busch Series is racing Saturday night at Gateway International Raceway, a 1.25-mile oval in Madison, Ill., near St. Louis.
2. The MotoGP motorcycle racing series returns to Mazda Raceway Laguna Seca in Monterey, Calif., on Sunday for the Red Bull U.S. Grand Prix.
American Nicky Hayden, the reigning series champion, has won the race the last two years but is struggling this season and is ninth in the points. Casey Stoner of Australia leads the standings with a 32-point lead over five-time series champion Valentino Rossi of Italy.
3. The IndyCar Series arrives at the 2.26-mile Mid-Ohio Sports Car Course in Lexington, Ohio, for the Honda 200 at Mid-Ohio on Sunday.
The Champ Car World Series ends its three-race swing in Canada on Sunday with the Rexall Grand Prix in Edmonton. And the Formula One series holds the Grand Prix of Europe at Nuerburgring in Germany.
4. Three-time and reigning Champ Car champion Sebastien Bourdais tested again with the Formula One racing team of Scuderia Toro Rosso, but there was no immediate word on whether he would drive for the team next year.
The Frenchman wants to switch to Formula One amid speculation that Toro Rosso might hire him to replace Scott Speed, the Manteca, Calif., native who has struggled. Speed is the only American driver in the series.
