Smoke to swap rides with F1's Hamilton

Two-time NASCAR Sprint Cup champion Tony Stewart and 2008 Formula 1 champ Lewis Hamilton are exchange race cars at Watkins Glen International.

The Mobil 1 Car Swap will take place June 14 at the well-known road course in the Finger Lakes region of upstate New York. Hamilton will take laps in Stewart's No. 14 Chevrolet and Stewart will climb into the cockpit of team Vodafone's McLaren Mercedes MP4-23.

"Tony and I will have some fun with the swap and make sure we put on a good show," Hamilton said of what will be his first foray in a stock car. "It's a racer's circuit and will give us both the chance to appreciate the differences between the two styles of racing at this legendary track."

Each will drive the long course at The Glen, which is 3.4 miles through 11 turns. NASCAR uses the 2.4-mile short course, which doesn't comprise the famed Boot section, but Stewart, who has a record five Cup victories at Watkins Glen, has determined it in a Grand-Am Rolex Sports Car Series race.

"When you've been around spirited racing for as long as I have, you really look forward to new experiences, and this car swap with Lewis is absolutely one of those opportunities," said Stewart, who also won an IndyCar Series title. "I already have quite a bit of respect for what Lewis and the F1 drivers and teams do, so to experience laps in the cockpit of an F1 car and see what Lewis can do in the Cup car is amazing I am really excited about."

The Glen became world-renowned by hosting the United States Grand Prix from 1961-1980 and has been home to NASCAR Sprint Cup races since 1986. This season marks the 50th anniversary of The Glen's opening F1 race.

Details of how many laps Stewart and Hamilton will make are still being worked out. They'll follow the lead of Jeff Gordon and Juan Pablo Montoya, who swapped rides at Indianapolis in 2003 when Montoya was heavy in F1.
