The car was fast but unreliable in testing and whilst Kimi Räikkönen used the car as best as he could in the early part of the season, Juan Pablo Montoya (who had joined the team from Williams) initially struggled to get to grips with the setup and unusual driving technique the car required over the Williams chassis he was used to. He was not helped by an off-track injury that put him out for two races early in the year. His stand-ins for those 2 races, Pedro de la Rosa for Bahrain and Alexander Wurz for San Marino finished fifth (including the fastest lap) and third respectively. Montoya eventually settled with the car and scored three wins and several podiums.
