Designing a Formula 1 chassis takes around 250,000 hours of labour and the actual construction requires a further 250,000.

During the design phase of the new FW27, WilliamsF1 created 4,500 drawings and roughly another 4,000 drawings will be added over the course of the season.

For its vehicles, WilliamsF1 produces approximately 200,000 individual components a year.

2004 San Marino GP

Michael Schumacher chalked up his fourth successive win of the season after forcing Juan Pablo Montoya's Williams onto the grass at the third corner. BAR's Jenson Button started on pole for the first time and finished second ahead of third-placed Montoya.

Italians' race

Watch out for Giancarlo Fisichella. Only two Italians have won the San Marino Grand Prix and both did so in Renault-powered cars - Riccardo Patrese with Williams in 1990 and Elio de Angelis for Lotus in 1985.

Sunday's race will be Italian Vitantonio Liuzzi's debut for Red Bull. The last driver to finish in the points on his Formula One debut was Germany's Timo Glock for Jordan in Canada last year.

Barrichello milestone

Ferrari's Rubens Barrichello starts his 200th race this weekend. The Brazilian is only the seventh driver to reach that mark.
