We must perform at Indy, says Montoya

The Colombian is anticipating a strong performance in America because of the tremendous power generated by the BMW engine. The F1 course at Indianapolis Motor Speedway features the longest full-throttle section of track in the championship.

"Our car can definitely do well at the Speedway as the power of the BMW engine suits the long straight, so I am anticipating a close fight with our immediate rivals," said Montoya. "We have two main targets to focus on now: the team needs to secure the Constructors' Championship and I have to close the gap to Michael in the Drivers' standings and, if possible, get ahead of him. We need to keep the ball rolling and make the most out of this race because Suzuka is a circuit that really suit's Michael's driving style."

Sam Michael, Williams' chief operations engineer, is anticipating a close battle at the Brickyard and admits that the team can no longer afford to make any mistakes.

"As the championship battle is so tight, any small error by the team will really hurt the title hopes," said Michael. "Points scored at the first Grand Prix are worth as much as the ones scored at the final races, however, at this time of the season there is not enough time for recovery.

"Strategy should be interesting at Indy as it has turned into a game of how little fuel you dare run. This is amplified when the cars and drivers are so close in terms of performance. We will be taking some new mechanical and aero components to help squeeze the last bit of performance out of the FW25 for these two vital final races."
