WATKINS GLEN, N.Y. (AP) - NASCAR star Tony Stewart and Formula One's Lewis Hamilton are swapping rides at Watkins Glen International.
They'll take turns navigating WGI's 3.4-mile long course on Tuesday - Stewart in his No. 14 Chevrolet and Hamilton in his McLaren Mercedes MP4-23.
Then, they'll switch cars in what's dubbed the Mobil 1 Car Swap at The Glen, with Hamilton taking the helm of a non-open-wheel race car for the first time and Stewart hopping in an F1 vehicle.
It promises to be an eye opener for both, but especially Stewart.
F1 cars are long, low and sleek, weigh about 1,400 pounds - a ton less than a Cup car - and are designed for road courses. They're also sleekly shaped, go well over 200 mph, and are capable of accelerating from zero to 100 and back to zero in 6 seconds with a V-8 engine that rolls at 18,000 rpm, about double what Stewart is used to.
