McLaren racing director Eric Boullier insists that cost-cutting plans being discussed will produce big savings for some Formula 1 teams, despite FIA president Jean Todt labelling them a 'joke'.
Todt expressed his disappointment about a three-year plan put forward for discussion by F1's Strategy Group during his visit to the Spanish Grand Prix.
He said that the concepts, first revealed by AUTOSPORT, FIA president Jean Todt would make little impact on teams' budgets - which he thought needed cutting by up to 40 per cent.
Boullier thinks, however, that technical regulations can be introduced that will have a major impact in bringing down costs.
And he thinks Todt's response was fuelled by the fact that some ideas that will save the big teams a lot of money may not have such as dramatic an impact on the smaller outfits.
"There is significant saving to be done, if we can present some good technical decisions in the regulations," said Bouller during a McLaren phone-in with media this
"One of the issues is that one effect, if for example you want to freeze one part of the car in terms of development, may have a different impact on cost-saving between Red Bull and Marussia.
"So this is where I think Jean was maybe a little bit disappointed - in seeing some discussions could have a big impact on saving for some teams but obviously smaller ones in some others."
Todt has asked smaller outfits to come up with proposals that they believe will save them money, at a time when many outfits are struggling with the increasing costs of competing.
