Surtees retained Brambilla for 1978, and Binder was replaced by Englishman Rupert Keegan. The first race of 1978 was the 1978 Argentine Grand Prix, in which Brambilla finished 18th and Keegan retired with overheating. At the Brazilian Grand Prix, the Italian failed to qualify and the Englishman retired due to a crash. The South African Grand Prix saw Brambilla finish 12th; Keegan retired when his engine failed. The Italian retired with transmission failure at the United States Grand Prix West; Keegan qualified but did not start due to a practice accident. For the Monaco Grand Prix, Brambilla drove the new Surtees TS20, but Keegan was still using the TS19 as there was only one TS20 available. Keegan retired with transmission failure. At the Belgian Grand Prix, the TS19's last race, the Englishman failed to qualify. There were two TS20 cars available for the rest of the year. The team had no Constructors points or driver points from the TS19 or the TS20 in 1978. Unable to raise sufficient money, the team left F1 after the 1978 season, despite having a car built for 1979. After racing the car in the British Aurora (formerly F5000) series briefly that year, Surtees Racing Organization ceased operations.
