FORMULA 1 ace Lewis Hamilton doesn't need to win in Brazil tomorrow (Sunday) to clinch the World Drivers' Championship.

The Vodafone McLaren Mercedes team are fully aware of the possible scenarios in Sao Paulo and are taking this into account in their grand prix preparations.

That means the team will take a slightly more conservative approach, as McLaren chief Martin Whitmarsh explained.

However, the team is still chasing glory in the constructors' competition, so will be hoping for good results from both Tewin racer Hamilton, 23, and Heikki Kovalainen.

"Clearly, we can afford to be more conservative than normal in our approach to Lewis's race," said Whitmarsh.

"But we are still pushing to win the constructors' championship and it would be wrong of us as a team to overlook this fact.

"There are 18 points available in Brazil and there's no reason why we can't take forward the pace and form we showed in China to achieve a one-two in Brazil.

"As a result, we do have a number of minor aerodynamic upgrades in the pipeline that we are evaluating for inclusion on our Brazil-spec car.

"As with every race this season, we have brought something to the car, even if it has only been generating a few extra hundredths' of lap time, and it would be wrong of us to close down that option for Interlagos."

Hamilton is seven points clear of Ferrari rival Felipe Massa and needs to finish fifth to win the world title.
