# 1968 Trans-American Championship

The 1968 Trans-American Championship was the third running of the Sports Car Club of America's Trans-Am Series. 1968 marked the addition of the 12 Hours of Sebring and the 24 Hours of Daytona, the only year that the Trans-Am Series featured those races. The season also marked the first time that an event was held outside of the United States, when a race at Mont-Tremblant brought Trans-Am into Quebec, Canada.
The championship was open to SCCA Sedans, which were required to conform with FIA Group 1 Series Production Touring Car or Group 2 Touring Car regulations. A Manufacturers Champion was determined in both Over 2-liter and Under 2-liter classes. The titles were awarded to Chevrolet (thanks to Mark Donohue's unprecedented 8 race winning streak, and Chevrolet winning 10 out of 13 races) and Porsche (thanks to Tony Adamowicz' 5 race class winning streak and Porsche's eight class wins in a row) respectively.
