known as the Fan Car: it won its first and only race at the Swedish GP, but Brabham did not use the car in Formula One again; other teams vigorously protested the fan car's legality and Brabham team owner Bernie Ecclestone, who at the time was maneuvering for acquisition of Formula One's commercial rights, did not want to fight a protracted battle over the car, but the victory in Sweden remained official. The Brabham BT46 Alfa Romeo flat-12 began the 1978 season at the third race in South Africa. It suffered from a variety of troubles that forced Lauda to retire the car 9 out of 14 races. Lauda's best results, apart from the wins in Sweden and Italy after the penalization of Mario Andretti and Gilles Villeneuve, were 2nd in Monaco and Great Britain, and a 3rd in the Netherlands. The Alfa flat-12 engine was too wide for ground effect designs in that the opposed cylinder banks impeded with the venturi tunnels, so Alfa designed a V12 for 1979.

In late September, during practice for the 1979 Canadian Grand Prix, Lauda cut short a practice session and promptly informed team principal Ecclestone, that he wished to retire immediately, as he had no more desire to "continue the silliness of driving around in circles". Lauda, who in the meantime had founded Lauda Air, a charter airline, returned to Austria to run the company full-time. McLaren comeback, third world title, and second retirement (1982–1985) In 1982, Lauda returned to racing, for an unprecedented $3 million salary.
