Early season promise faded as the radical looking 'tusked' Williams FW26 initially lacked pace and both drivers were frequently left struggling to score points. However, the car was significantly overhauled during the season and the radical nose designed by a former Ferrari aerodynamicist was finally replaced with a more conventional one for the final stages of the season. Montoya left the team on a high note by winning his last race with them, the 2004 Brazilian Grand Prix, which was closely contested with future McLaren teammate Kimi Räikkönen. Overall, he finished the season in 5th position in the Drivers' Championship.
