McLaren’s answer to the end of the turbo era: a V10-powered title winner shaped by speed, technical change and one of racing’s fiercest rivalries.
Formula 1 moved to naturally aspirated 3.5-litre engines for 1989. Under Neil Oatley, McLaren created a new carbon-fibre monocoque around Honda’s RA109E V10, retaining the disciplined packaging and aerodynamic clarity that had made its predecessor so formidable.
Ayrton Senna and Alain Prost won ten of the sixteen races between them. Their relationship deteriorated dramatically, but the MP4/5 remained the benchmark: McLaren secured the Constructors’ Championship and Prost took the Drivers’ title.
This car is remembered not only for what it won, but for the tension it contained. Two exceptional drivers, two contrasting approaches and one garage produced a season that still defines how sporting rivalry is discussed.
The MP4/5 proved that McLaren’s 1988 success was not dependent on turbo power. It carried the team directly into Formula 1’s new naturally aspirated era—and kept it in front.
