# 1970 Trans-American Sedan Championship

The 1970 Trans-American Championship was a motor racing series organised by the Sports Car Club of America for SCCA Sedans. It was the fifth Trans-Am Championship. Ford won the Over 2 Liter title and Alfa Romeo were victorious in the Under 2 Liter class.
With Porsche's 911 moving to a 2.2L engine, the year marked the resurgence of Alfa Romeo as dominant in the Under 2 Liter class. The year also marked the first race win for American Motors, with Mark Donohue driving a Penske Racing-prepared AMC Javelin, winning three races. Also winning for the first time was BMW, in the Under 2 Liter races at Bryar and Bridgehampton.

## Schedule

The championship was contested over eleven rounds with separate races at each round for Under 2 Liter and Over 2 Liter cars.
