New FIA president Jean Todt has joined the discussion on KERS, suggesting that it may be possible to reintroduce the so-called 'green' technology when the cost of competing in Formula One is again addressed for nest season.

Speaking to Associated Press ahead of the Spanish Grand Prix, Todt reiterated his commitment to reducing the amount of money needed to compete in the top flight, but confirmed that the reintroduction of KERS - used by some in 2009, but unanimously suspended for 2010 - could come as early as 2011. The issue has been the subject of debate almost since the current season got underway in Bahrain, but has yet to achieve a consensus opinion from team owners, with many backing the return but others strongly against it.

"We need to let the new teams live, to survive," Todt said, "We can do this by reducing costs and by doing a lot of things to improve the show. We need to put vigour into new technologies because F1 should be an ambassador to new technology. I have hope that sponsors will then come back, and that will allow teams to compete in F1."

The KERS debate was again raised during Friday's FIA press conference, where four of the sport's leading technical directors debated not only the possible date for its reintroduction, but whether it was needed at all.

"At Williams, we have always been supportive of KERS, and we see it as part of F1 in the future," Sam Michael commented, "The exact timing of when it is introduced is something that is still being debated within FOTA, and I think the idea was to have the final decision this weekend as everyone has got to get on and design their cars for 2011.

"But there are obviously different technologies out there and, as you said, [Williams] have vested interests. We have battery technology and fly-wheel, and I think that is a secondary or even third order of decision. The main thing is we just want to see a plan whether it is next year or later when it is going to be introduced. That is still going around for discussion at the moment, but we are fully supportive of it.

"There is definitely a strong possibility that we will run KERS in 2011, but we won't be alone. It is under discussion at FOTA at the moment, so we can try and come to some consensus as to what we do. But it is in the regulations, [and] it is in this year's as well. It is only because of the agreement that no-one ran it this year."

Ferrari's Aldo Costa confirmed that the Scuderia would join Williams and Renault in supporting the reintroduction of KERS next year, and pointed out that, along with the regie, he was pushing for the system to have a greater performance increase than allowed in the 2009-10 rules.

"With the same system, we think, with a more revised system, we can achieve from it much more and the application can be used also during a weekend or during a race for other purposes and for better integration of the KERS in the vehicle to reach the proper status of hybrid vehicle," Costa claimed, "At the moment, it isn't as it is written, so we are proposing that but, unfortunately, there is not a lot of consensus at the moment.

"Another possibility is to use KERS for the sport to have a better show, so to write a sporting rule that allows the use of KERS for overtaking again is another good aspect, I think, for F1. We are keen to use it, we are keen to develop it, we are keen to give to KERS more and more importance in the next few years."

"I think KERS is definitely the future," Mercedes' Ross Brawn agreed, "I think the concept of the new engine in 2013 is very much around a core internal combustion engine of some sort, but [with] a lot of technologies around it. The philosophy will be that those technologies are the areas that will be the focus of attention for development.

"We are very supportive of that, and I think we have to recognise that KERS is in the regulations at the moment, so anyone within the regulations can use KERS next year. There was an agreement within FOTA in order not to escalate the costs that teams could use KERS if they could meet some target figures in terms of costs and if they could make their system available to customers for those costs, so I think as long as people meet those requirements, then KERS could be seen next year.

"We welcome any of those technologies. Whether we will do it or not we will have to look at all the numbers. But we are certainly not against KERS. We think it is a good technology."

Interestingly, while Hispania Racing's Colin Kolles has made his opposition to the reintroduction of KERS well known, Virgin Racing supplier Nick Wirth said that he was open to its use, even though the team was currently working under one of the tightest budgets in the sport and would probably support a later introduction date.

"For us, it represents quite a challenge," Wirth admitted, "Obviously, we have not had the experience of packaging that, and neither has our engine supplier, but we absolutely support the principal of it and the principal of introducing hybrid technology to F1.

"However, we entered F1 under a different set of regulations which have actually come to pass this year and I think everyone has to bear in mind that we are supplying and building F1 cars to Virgin Racing which are cheaper than a Bugatti Veyron, so for us to introduce [KERS] with this kind of cost limitation that we have is quite a challenge. We think it is probably the most appropriate to look at that for the 2013 technology when we can choose the appropriate storage medium and integrate that in the new engine regulations."

Todt has described his first six months in charge of the sport as 'tough', but insisted that he was determined to see though his policy of cutting the cost of competing, even if he did not necessarily support predecessor Max Mosley's idea of a spending cap.

"There are other ways to cut costs, it doesn't have to come from a cap - they are two different things," he claimed, "We know that F1 costs too much and that's one of the things we've reflected on in our bid to cut costs. There is obviously a terrible disparity between teams."

Despite his drive to contain costs, however, the diminutive Frenchman is also determined to spice up the show, and he has proposed further changes to the rulebook in order to achieve that aim.

"Unless there are extreme conditions or difficult meteorological conditions, logic says the car in front stays in front for the whole race and a lot of it is due to aerodynamics," Todt said, "When we start to think of new rules from 2013, with a new powertrain, then we have to fundamentally lower the importance of aerodynamics in the race, and that should provide a big boost to overtaking on the course."
