The McLaren MP4-18 (sometimes stylised as McLaren MP4/18) is a Formula One car which was built with the intention to compete in the 2003 Formula One season. The car, designed by Adrian Newey, Mike Coughlan, and Neil Oatley, was a radical new design that incorporated numerous ideas that were still in their infancy in Formula One. Many of these ideas would be used again, such as the blown diffuser on the Red Bull RB7. Several problems with the car that revolved primarily around cooling the engine and gearbox meant that the car was stillborn and never raced.
