History of the Trans-Am Series

The Trans-Am series is an automobile racing series that was created in 1966 by Sports Car Club of America (SCCA) President John Bishop. Originally known as the Trans-American Sedan Championship, the name was changed to the Trans-American Championship for 1967 and henceforth. The series has in fact gone by a variety of different names through the years, some linked to sponsors, some not. It has evolved over time from its original format as a Manufacturers' Championship series for modified passenger sedans and Coupés to its current form as a Drivers' / Manufacturers' Championship Series that is open to GT style racecars. Champion drivers have been officially recognized, and Drivers' Championship(s) have been awarded since the 1972 season.

The series was formed at the dawn of the pony car era, and was derived from the SCCA's A & B Sedan amateur Club Racing classes, Early Trans-Am Series racecars were just modified production cars. The series was open to FIA Group 2 Touring Cars, and it featured two classes: "Over 2.0 Liter"—111 inch wheel base or less and engine displacement limited to 5.0 liters / 305 cubic inches (primarily American pony cars), and "Under 2.0 Liter" (predominantly European sedans), with both classes running together.

The series was best known for competition among American V8 coupes such as the Ford Mustang, Chevrolet Camaro, Plymouth Barracuda, Mercury Cougar, AMC Javelin, Pontiac Firebird, and Dodge Challenger in the 1960s and early 1970s, driven by some of the most famous names in auto racing, like Mark Donohue, Parnelli Jones, Dan Gurney, Sam Posey and Bob Tullius, to name just a few. Marques such as Porsche (until its 911 was reclassified as a sports car and not a sedan), Alfa Romeo, BMW, Datsun, Mini Cooper, Saab, and Volkswagen competed in the series' Under 2.0 Liter category.

Over the years, the series has raced on a variety of different types of race tracks (Permanent and temporary road courses / street circuits / airport circuits) all over the country, as well as at venues in Canada, Mexico, and even San Juan, Puerto Rico in 2003. Since 2015, Trans Am has been a national series (Continental U.S. only), racing at tracks primarily throughout the East Coast, South, and Midwest. Since the 2017 season, the stand-alone West Coast Championship Series has raced at four tracks—three on the West Coast, and one in Texas that is a 'shared event' with the Trans Am Championship Series. Each Championship Series is independent of the other, but both are run according to virtually identical rule books.

The Trans-American Sedan Championship commenced on March 25, 1966, at Sebring International Raceway, beginning a 7 race season. (After 1966, seasons would average 12 rounds until 1973) The overall win went to Jochen Rindt driving an Alfa Romeo GTA, a very successful car in Trans Am, until Porsche arrived. Bob Tullius (in a Dodge Dart) took second overall and first in the Over 2.0 Liter class.

Allan Moffat, in a 1600cc Lotus Cortina, won the third race at Bryar. Ford of Britain gave full factory support to the Alan Mann Lotus Cortinas. In 1966, the Over 2.0 Liter Manufacturers' Champion was Ford, with the Mustang of Tom Yeager and Bob Johnson scoring most of Ford's wins and points. The Under 2.0 Liter Manufacturers' Champion was Alfa Romeo, with Horst Kwech and Gaston Andrey's Alfa Romeo GTA scoring 39 of the 57 Manufacturers' points for Alfa.

For 1967, in the Over 2.0 Liter class, Ford edged out Mercury for its second Manufacturers' Championship. Porsche successfully lobbied the SCCA to reclassify the 911 as a sedan, and then went on to dominate the Under 2.0 Liter field, winning the first of ultimately three consecutive Manufacturers' Championships over Alfa Romeo. The second season would see the emergence of now familiar names like Mark Donohue (3 wins, 2 of them without a co-driver) and Dan Gurney.

The 1968 season was notable for the addition of the 12 Hours of Sebring and the 24 Hours of Daytona, the only year the Trans-American Championship featured those races. The '68 season also marked the first time the series ever left the United States, as the race at Mont-Tremblant, Quebec introduced Trans-American Championship racing to Canada. From 1969 on, co-drivers were not used, as most of the races were between 2.5 and 3 hours.
