Williams get into gear with launch of 2004 challenger

Williams will begin the countdown to the new Formula One season in earnest today when they launch their 2004 challenger in Spain.

The FW26 will be unveiled in Valencia before Williams begin an intensive testing period as they look to finally topple Ferrari, having come so close in both championships last year.

Juan Pablo Montoya was favourite with just a couple of races left last year, but his and the BMW-powered team's challenge in the constructors' battle faltered when it mattered most.
