The car was driven by triple World Champion Ayrton Senna, in his sixth season with McLaren, and by Michael Andretti - son of World Champion Mario Andretti - who joined Formula One from CART. After the Italian Grand Prix, Andretti returned to America and was replaced by the team's test driver Mika Häkkinen. Senna drove the car to victory on five occasions, finishing runner-up to Alain Prost in the Drivers' Championship, while McLaren were runners-up to Williams in the Constructors' Championship.
