Red Bull still improving 2011 car - Newey

Red Bull technical director Adrian Newey has revealed his team is still pushing the development of this year's car in order to secure the constructors' championship as soon as possible.

Sebastian Vettel has all but won the drivers' crown, needing just one point from the remaining five races, but the constructors' title is less certain as Red Bull leads McLaren by 138 points with a maximum of 215 still up for grabs. Although Red Bull is by far the favourite, Newey said his design team would not slacken its efforts and has not yet committed its full attention to the 2012 car.

"It's that time of the year now where we desperately want to get the double in the championships if we can," he said. "We want to keep pushing the current car, keep it reliable if we can, and then we really have to have our attention on next year's car at the same time. We're deep into the design of the chassis and the gearbox [of the 2012 car], and as the two longest lead items we have to be, time scales demand that.

"But the things we learn on this car can go into next year's car and vice-a-versa. The regulation changes are fairly small for the winter, the most significant one is that we are much more restricted with what we can do with the exhaust system, but apart from that it's fairly similar rules."

He added: "It's a matter of keeping our feet on the ground; things can easily go wrong still. We're not there in the constructors' yet and we've still got five races to go. We'll continue to take each race race-by-race and try to do the best job we can and hope that that's good enough."

After winning back-to-back races at Monza and Singapore - two very different circuits - team principal Christian Horner congratulated his team on producing such an adaptable car this year.

"What's been really gratifying this year is that we've been competitive from Monaco to Monza and I think that's testimony to hard work in the team and from lessons learned last year," he said. "I think Adrian and his team have done a brilliant job in making the car versatile for different types of track and this track is probably the toughest test on the calendar in terms of the punishment that car gets round here with the kerbs and the bumps and the heat."
