Two-time Formula One world champion Fernando Alonso has commented that if the sport introduces a standard engine rule for all Grand Prix cars it would be "the final straw".
The fiery Spaniard told reporters at a charity event that if the idea becomes reality "it would be time to start thinking about retirement".
The sport’s ruling body, the FIA thinks the idea could help Formula One cope with excessive costs and survive the economic downturn which is threatening its future.
But he was more welcoming about next season’s changes which will see the return of slick tyres and greater encouragement of overtaking.
The Renault driver likes the fact "that practically everybody is starting from zero".
So what are his ambitions for the coming season?
He said: "My objective is to win the title. It’s a very clear objective, although it may have to be altered as the year goes on."
Alonso won the championship in 2005 and 2006 and has proved to be a serious rival to Lewis Hamilton’s chances of winning races.
