A number of Formula One teams have welcomed the idea of a possible return of the Kinetic Energy Recovery System (KERS) to the sport for 2011, although only if the system is more affordable.

Team principals discussed the possible re-introduction of the power boost system during a Formula One Teams' Association (FOTA) meeting in Sepang on Friday ahead of the Malaysian Grand Prix.

McLaren, Ferrari, Renault and BMW all used KERS in 2009 before the latter two teams chose to stop using the system during the season, feeling their cars were quicker without it.

The technology has been abandoned for this season due to the high cost involved in running the system but McLaren team principal Martin Whitmarsh, who is also chairman of FOTA, admitted he would be keen to see the technology re-introduced next year - as long as the high costs involved were brought down to a more manageable level.

"KERS is something we obviously ran successfully and enjoyed the technology last year," he said. "We support the idea of KERS in Formula One and we would love to have it.

"What we have to do is look at the bigger picture. If we had to reintroduce KERS we would have to decide at what speed we would re-introduce it and also whether it is affordable.

"It is an issue where a lot of the teams cannot afford KERS next year. That is why we need some understanding and something that is affordable and worthwhile for the sport."

Renault and Ferrari are believed to be among the teams most keen to see the system reintroduced while Williams team principal Sir Frank Williams would welcome the return, provided it can be made affordable to all teams.

"There's general agreement it should have a place in Formula One," he said.

"I believe it should be compulsory or not at all. It's appropriate if it's not too expensive."
