McLaren technical director Paddy Lowe insists the team isn't concerned about the ban on exhaust-blown diffusers for the 2012 F1 season despite suggestions that some teams have found a loophole to try and get around the change in regulations.

With the controversial systems not allowed for next season, and restrictions in place on exhaust positioning, teams are looking at other ways to improve downforce and Lowe said he was ready for the challenge that the new regulations will bring as he seeks to help McLaren produce a championship challenger with the new MP4-27.

McLaren technical director Paddy Lowe is unconcerned about next season's ban on exhaust-blown diffusers and the possibility that some teams may find ways to continue to exploit exhaust gases in 2012.

While peers at other teams have expressed concerns about possible loopholes in the revised regulations, Lowe is unfazed and is instead relishing the challenge of doing all he can - within the new limitations - to make next year's McLaren MP4-27 as quick as possible.

"I'm not in fear over it," he said during a Vodafone McLaren Mercedes Phone-in. "I don't quite understand when technical directors say they fear stuff like that. What is their fear of? The clue's in the name - Formula One. It's a formula - a set of constraints - that we define in the regulations. And once they're set we'll go and work as hard as we can to do as much as we can to make the car quick within those limitations.

"We had a bit of a crisis in Silverstone this year with the exhaust blowing situation and reached some agreement in terms of intent next year," he explained. "The teams have since worked on a range of limits to reduce the amount at which exhausts can be used to create downforce, but it's never been expected that it would eliminate the effect of exhausts on downforce.

"That would be unrealistic. No regulation we've ever written has eliminated an in-car effect. There will be a finite effect. The simple point is that pointing an exhaust out the back will give you a large degree of thrust. That is an aerodynamic fact, but we all know that we can get a lot more than that. And the teams went into that with eyes wide open.

"So I do find it a bit odd when people claim that they fear that people will generate performance from exhausts. Well of course they will. That's what we have to do. It's just that some very extreme limits have been put in place to reduce that drastically from where it was."

Turning focus back to the job at hand, Lowe revealed that McLaren will take a series of new aerodynamic parts to India this weekend for the first race at the new Buddh International Circuit in an effort to fight for victory.

"We are bringing some new aerodynamic pieces to this event," he said. "We have a new front wing, so that's the main thing and something we hope to take forward through to the last few races of the season. But we are winding towards a close with what we'll bring in terms of updates this year. But things like the front wing will carry forward to next year as the regulations on the front are exactly the same."
