KERS has few friends in Formula One
Once hailed, now failed: Formula One's kinetic energy recovery system (KERS) appears to be surging towards the scrap heap at the end of
Offering drivers a brief boost of power at the push of a button, KERS was introduced this year as greener technology that would help
Formula One to move away from its gas-guzzling image, contribute to road car development and liven up the sport with more overtaking. It has
not worked out that way, even if there have been a few highlights such as world champion Lewis Hamilton's ultimately unsuccessful
KERS-propelled surge into the first corner at the Nürburgring last weekend.
Ferrari boss Stefano Domenicali said on Sunday that the team had frozen development of a system that stores energy generated by the car's
brakes and makes it available as a burst of extra power for overtaking or to stave off a rival. It has been used by only four of the 10
teams since the Australian season-opener in March.
None of the four - McLaren, Ferrari, BMW Sauber and Renault - has won a race with it and only Ferrari has stepped onto the podium, once.
All have spent millions of dollars on development.
The Formula One Teams Association (FOTA), whose eight members include all the manufacturer-owned teams, has agreed to jettison the system
for 2010 even if it remains in the regulations as an option at present.
"We have discussed the KERS issue within FOTA and we had a majority agreement not to use KERS next year," said BMW Sauber team
boss Mario Theissen, one of the system's biggest backers when it was introduced. "We had supported KERS but we have committed to the
agreement... so we will not run KERS and there was no FOTA member voting for KERS."
BMW finished third in last year's constructors' championship with 135 points but has scored just eight this season. Between them, the
four KERS teams have fewer points than Brawn's championship leader Jenson Button after nine races.
At last month's British Grand Prix, Ferrari was the only team to use KERS.
Theissen hesitated to call it a failure, however.
"I still think that KERS would have been very good, not just for BMW as a manufacturer but also for Formula One as a whole because
it is a very credible piece of innovation relevant to future road cars which Formula One has pioneered and really pushed forward," he
said. "We are using it, we have transferred it into road car projects already. All the guys who have done the Formula One system are
working on road car projects now. So this really could have been a big story for Formula One."
The problem, he said, was that the governing International Automobile Federation (FIA) agreed to make use of the system voluntary. While
that helped teams such as championship leaders Brawn, which was left without a KERS system when Honda withdrew, it has worked against those
carmakers who spent heavily on the technology and believed it would ultimately give them an advantage. Toyota and Williams were among those
to develop systems that have yet to be raced.
"In terms of competitiveness it is no coincidence probably that all the four top teams of the past three years have gone backwards
collectively," said Theissen. "It's been these four teams that have come up with KERS and what we have learned is that if you want
to pioneer an innovation, you have to fully back it. If you do it optionally, it won't work, it won't fly. You have to make it
Mercedes has been credited with the most efficient and reliable KERS system but the McLaren car has struggled for pace.
"If we didn't have KERS, then the overall packaging of the car would change and there would be some pluses from that but overall we
have a good benefit," said McLaren boss Martin Whitmarsh. "It is our intention at the moment to continue running KERS for the rest
of the year. The alternative strategy is to redesign the whole car without KERS and that takes a lot of resource and frankly would detract
from next year's programme."
Mercedes motorsport head Norbert Haug said KERS gave Hamilton three-and-a-half tenths of a second per lap at the Nürburgring last
weekend but Whitmarsh recognised the advantage had to go.
"KERS is still in the regulations for next year but we have accepted that part of the new era of Formula One has got to be
cooperation among the teams; you've got to sometimes forego your short-term self interest in the interests of the sport," the Briton
told reporters. "We've accepted that the majority of teams in Formula One do not want to have KERS and therefore we are willing to
sacrifice the advantage that we have at the moment."
Williams, a team which keeps a very close eye on costs, has been developing its own flywheel version of KERS but has yet to race it. Team
boss Frank Williams said all was not lost, however.
"It has very useful and truly interesting commercial applications. It's got its own life in that direction," he said.
