The Group 2 racing class referred to regulations for cars in touring car racing and rallying, as regulated by the FIA.
The FIA established Appendix J regulations for Touring and GT cars for 1954 and the term Group 2 was in use to define Touring Cars in the Appendix J of 1959.
[1] By 1961 Appendix J included specifications for both Group 1 Series Touring Cars and Group 2 Improved Touring Cars with a minimum production of 1,000 units in twelve consecutive months required to allow homologation of a model into either group.

[6] The Sports Car Club of America’s Trans-American Sedan Championship was contested by Group 2 touring cars from its inception in 1966 through to the 1972 season.
