Monaco GP winner Juan Pablo Montoya and NASCAR ace Jeff Gordon will trade places tomorrow [Wednesday] at the Indianapolis Motor Speedway when they take turns driving speed demonstration laps around the 2.606-mile road course in Gordon's DuPont Chevrolet Monte Carlo and JPM's BMW WilliamsF1 FW24.

This will be the first time that Gordon and Montoya will be behind the wheel of a Formula One car and NASCAR Winston Cup car, respectively.

Gordon will attempt to win his fourth Brickyard 400 on Sunday, Aug. 3 at the Speedway. The demonstration laps will be his first laps on the IMS road course.

Montoya, who won the 2000 Indianapolis 500, will attempt to become the first driver in Speedway history to win on both the famed 2.5-mile oval and road course when he competes in the fourth United States Grand Prix on Sept. 28.

Montoya and Gordon will participate in a media luncheon and press conference as well. Fans will have free access to IMS' South Terrace grandstands for viewing.
