Force India admits Ferrari switch possible
Ian Phillips, the Silverstone based squad's director of business affairs, said current customer supplier Ferrari is being "non-committal" about packaging a KERS system to go with its engine next year.
"Ferrari don't want us to develop our own system, but are being a bit non-committal about whether they are even going to start the season with KERS," he said on BBC's radio Five Live from Fuji Speedway.
"Force India has to build a new car for the new regulations, and can't afford to build a non-KERS car and then have whoever turn around and say that KERS will be available from July or whatever," Phillips added.
He said it is "natural" that Force India, already linked with switches to Honda or Mercedes-Benz, is therefore asking other manufacturers about what they can offer.
