High Quality Content by WIKIPEDIA articles! The Road America 500 is a sports car race held at Road America in Elkhart Lake, Wisconsin. The event began in 1957 as an SCCA National Championship series race. In 1963, the race shifted to the new United States Road Racing Championship, until the USRRC's demise in 1968. After an 11-year hiatus, the IMSA GT Championship revived the event in 1979. IMSA shortened the race to 500 kilometers in 1988, and shortened it again to 300 km in 1991, and 2 hours in 1992. After a return to 500 km, the race was cancelled for 1994. It was again revived in 2000, by the Grand American Road Racing Championship, at a 500-mile distance. The race has been an American Le Mans Series event since 2002, and after 2003 has been a 2 hour, 45 minute race (with the exception of 2007 and 2008, when 4 hours were scheduled). Porsche have won the event nine times, most recently in 2007. Augie Pabst, Chuck Parsons, and Geoff Brabham have each won three times as drivers.
