Williams launch their car for the 2004 season in Spain today with Juan Pablo Montoya insisting that he can still win the Formula One drivers' championship with the British team despite agreeing to join McLaren-Mercedes in 2005.
The FW26 will be unveiled here before Williams begin an intensive period of testing as they set about finally beating Ferrari having come so close in both championships last year.
Montoya, who finished third last season, will be taking part in his fourth and final car unveiling for Williams. His team-mate, Ralf Schumacher, will also be at the launch with talks still continuing over his future with Williams.
There has been speculation that the German is using Montoya's departure to improve his contract. Schumacher said: "The real reasons [for the delay] are confidential. I would not expect anything to happen in the near future."
