The team began the 1978 campaign with the pairing of its reliable McLaren M23 and Lunger, who was returning for his second season driving for the team. After just 4 Grands Prix the switch to the new M26, which had been purchased in the off-season and tested by Lunger was made. Subsequently Lunger posted the 3 best performances of his Formula One career, a 7th-place finish in the Belgian Grand Prix and an 8th at both the British and Austrian Grands Prix. With Lunger having some success in the McLaren M26, the team placed Brazilian rookie, and future 3-time Formula One World Champion Nelson Piquet in its M23 for its final 3 Grands Prix of the season. Piquet was able to post a best finish of 9th in the Italian Grand Prix.
