The flywheel-based KERS system developed by Williams for formula one will instead be fitted to Porsche's new 911 GT3 R Hybrid race car.
The Grove based team told the media on Thursday that its energy recovery system, developed throughout 2009 but disallowed as part of a FOTA agreement this year, will be unveiled in the Porsche at the Geneva Motor Show next month.
"We hope that this will be just the start of the evolution of hybrid systems developed for formula one moving across to applications where they can contribute to cleaner and more powerful vehicles," said Williams' chief operating officer Alex Burns.
Williams said the technology will also be available to buses, trains, ships and wind power generation.
Aboard the Porsche 911, however, Williams' KERS will see some racing action, with the German carmaker announcing it will contest May's Nurburgring 24 hour race.
