Williams focuses on Constructors' title

The British team trails Ferrari by just three points going into the final race of the season, and BMW motorsport boss Mario Theissen reckons that the disappointment of losing the Drivers' title will spur the team harder in the fight for the Constructors' crown.

"Naturally the way the Indianapolis race went was a big disappointment for the entire team," said Theissen. "But disappointments are part of the sport, and you have to accept this as part of the challenge. We have digested the result of the US GP and we all now feel determined to make the most of our chance to win the Constructors' title in Suzuka."

Williams has been testing this week at Jerez in Spain in preparation for the season finale, and will run new compound Michelin tyres at Suzuka in their bid to topple Ferrari.

"I am sure we can claw back the three points on Ferrari, and the team's test in Jerez this week makes me confident that we can achieve this," said Ralf Schumacher. "As it will be so compelling to watch, I am sure the finale will be well worth an early wake up call for every Formula 1 fan."
