Jason C. Leffler (September 16, 1975 – June 12, 2013) was an American professional stock car racing driver from Long Beach, California. Leffler began racing in the open-wheel ranks, competing in the 2000 Indianapolis 500 before moving to primarily NASCAR competition. He died from injuries sustained in a 410 sprint car race at Bridgeport Speedway in Bridgeport, New Jersey.
Leffler began his career racing midget cars in the USAC series, where he won three consecutive midget championships from 1997 and 1999, as well as the Silver Crown series championship in 1998. He was the third driver to win three consecutive midget car championships. He won the Hut Hundred and Belleville Nationals in 1997, and the Turkey Night Grand Prix and Copper Classic in 1999.
He won his second Turkey Night Grand Prix in 2005.
Irwin then went on to race in USAC. He began open wheel racing in 1991. He had 7 career USAC Sprint Car Series wins, and was the series Rookie of the Year in 1993. In 1994 he was the USAC Silver Crown Series Rookie of the Year and finished second in the 1995 USAC standings.
In 1996 he was the USAC National Midget Series champ. After his successful run in USAC, many open-wheel enthusiasts began comparing him to NASCAR's Jeff Gordon.
Roger Penske met Leffler at the 1998 Hut 100. Leffler's success also caught the attention of Joe Gibbs Racing, a team which had previously signed Tony Stewart from the USAC ranks. Leffler joined the team in 1999 and made four starts in the Busch Series during the season with moderate success.
At the same time, he also started a race in the Indy Racing League at Walt Disney World Speedway in the No. 5 Treadway Racing machine, but finished last after crashing early in the race.
In May 2008, Junior formed RP Automotive, Inc. and purchased Penske Ontario from his dad, renaming it Penske Honda of Ontario. To date, he has opened the following dealerships: Penske Honda of Ontario Penske Toyota Scion of Rancho Santa Margarita Penske Toyota of Downey Penske Mercedes-Benz of West Covina Penske Audi West Covina Penske GMC Buick of Cerritos Penske Chevrolet of Cerritos Penske Chevrolet of Buena Park Penske Cadillac Buick GMC South Bay
Leffler made his first, and only, start in the Indianapolis 500 in 2000. This effort was put forth by Treadway Racing with backing from Roger Penske's United Auto group. Leffler qualified in the 17th position, which was also where he finished; three laps behind race winner Juan Pablo Montoya.
