The Trans-Am Series is an automobile racing series created in 1966 by the Sports Car Club of America. Originally known as the Trans-American Sedan Championship it has evolved over time from its original format as a manufacturer's championship for modified racing sedans to its current form as a driver's championship open to GT style cars.
The series was formed at the beginning of the pony car era and came from the SCCA's A & B Sedan amateur Club Racing classes, which were based upon commercially produced cars which had been modified for racing competition. Originally the series was open to FIA Group 2 Touring Cars and it featured two classes, over 2.0 Liter and Under 2.0 Liter, with both classes running together. The series was best known for competition among American V8 sedans such as the Ford Mustang, Chevrolet Camaro, Plymouth Barracuda, Mercury Cougar, AMC Javelin, Pontiac Firebird, and Dodge Challenger in the 1960s and early 1970s.
The first race was in 1966 at Sebring International Raceway. The overall win went to Jochen Rindt driving an Alfa Romeo GTA an Under 2-Liter car, with Bob Tullius driving a Dodge Dart, taking second overall and first in the Over 2-Liter class.
This car is an example of the early period in Trans Am racing.
