The year started very promisingly, with one win each for Coulthard and Räikkönen at the first two Grands Prix. However, they were hampered when the MP4-18 car designed for that year suffered crash test and reliability problems, forcing them to continue using a 'D' development of the year-old MP4-17 for longer than they had initially planned. Despite this, Räikkönen scored points consistently and challenged for the championship up to the final race, eventually losing by two points. The team began with the MP4-19, which technical director Adrian Newey described as "a debugged version of MP4-18". It was not a success, though, and was replaced mid-season by the MP4-19B. With this, Räikkönen scored the team's and his only win of the year at the Belgian Grand Prix, as McLaren finished fifth in the Constructors' Championship, their worst ranking since 1983.
