Ferrari's Fernando Alonso has refused to relinquish his chances of winning the world championship this season.
The Spaniard finished second to Red Bull's Sebastian Vettel at the Indian Grand Prix on Sunday and now trails the German by 13 points in the Drivers' Championship.
"It is not easy to fight Red Bull but we will never give up," said Alonso. "Well done Red Bull and Sebastian but we want to be happy in Brazil, not only here. I am sure we will do it.
"We lost points but this is what we expected this weekend as we are not fast enough, but we lost minimum points and there will be better races to come.
"We were fast in a straight line but still missing grip in the corners - hopefully that will come in the next few races."
There are three more races remaining this season.
