The McLaren MP4/14 was a Formula One car built and designed by the McLaren-Mercedes team to compete in the 1999 Formula One World Championship. Designed primarily by Neil Oatley and Henri Durand under the direction of Adrian Newey, Mario Illien provided McLaren with its bespoke engine. The car gave Mika Häkkinen his second Formula One Drivers' Championship in a row, but McLaren was unable to defend their title in the World Constructors' Championship, losing narrowly to Scuderia Ferrari.
