But since the track opened as NASCAR's first superspeedway with the 1950 Southern 500, Darlington has come to be known for stock-car racing. Open-wheel cars haven't been there in more than 50 years.
That will change next week, however. The U.S. Auto Club will hold a test session for its Silver Crown series cars at Darlington next Thursday and Friday.
The USAC Silver Crown series is in its second year of competition with a new style car built for competition on pavement. The cars weigh 1,700 pounds without a driver, roughly half the weight of a Nextel Cup car, and have engines that generate 750 to 800 horsepower. ThatsRacin.com
