The 1978 season opened with defending champion Niki Lauda having departed Ferrari at the end of 1977, redistributing the competitive field. Lotus, under Colin Chapman, had developed the ground-effect Lotus 78 and 79, giving Andretti and Peterson a significant aerodynamic advantage over rivals.
Mario Andretti drove for JPS-Lotus across sixteen races, securing the Drivers' World Championship and making Lotus the Constructors' Cup winner. The season was marked by tragedy: Ronnie Peterson died from complications after an accident at Monza, and Gunnar Nilsson died from cancer having retired the previous year.
Andretti remained the last American Formula One World Champion. Lotus claimed its final Constructors' title. Peterson was awarded second place posthumously, while Lauda finished fourth with Brabham and Ferrari's Carlos Reutemann took third, signalling the decline of the Ferrari–Lauda partnership's dominance.
