The 1970 Trans-American Sedan Championship season was the fifth season of the Sports Car Club of America’s Trans-Am Series. All races used split classes with shorter races for the Under 2-Liter cars. With Porsche’s 911 moving to a 2.2L engine the year marked the resurgence of Alfa Romeo as dominant in the U2L class. The year also marked the first win of American Motors with Mark Donohue driving a Penske Racing-prepared Javelin winning several races.
