AUSTIN, Texas (Reuters) - Ferrari's Sebastian Vettel refused to give up on the Formula One championship on Thursday and found support from title favorite Lewis Hamilton.
Hamilton leads the German by 59 points with four races left and the Mercedes driver can take his fourth championship in Sunday's U.S. Grand Prix if he finishes in the top two and results go his way.
"In English, they say it’s not over until the fat lady sings," Vettel told reporters in the U.S. Grand Prix paddock. "We need to make sure she shuts up for quite a while."
Vettel led the championship from the opening race in Australia in March until last month but three races in the Far East and Hamilton's string of wins have shredded his chances.
The Ferrari (NYSE:RACE) driver was caught in a collision with team mate Kimi Raikkonen in Singapore and crashed out on the opening lap, then suffered an engine failure in qualifying in Malaysia that left him last on the grid.
He raced back to fourth that time but in Japan was sidelined by a broken spark plug.
"We are still in there, our chances are slimmer than they have been some races ago. There is a chance. We’re going for it," said the four times world champion.
"We need to stay focused. We have a great car, we had a package to win the last couple of races. As it happens, we didn’t. But that doesn’t mean we have no chance to win the next races."
Hamilton, who has won in Austin four times in the last five years, said talk of wrapping up the title in Texas - as he did two years ago - was overblown.
"I think the talk of the championship win this weekend is silly really...you can’t expect them to have a difficult weekend again," he said.
"They’re going to be quick, they have an opportunity to win. The championship, as long as it’s done in the next four races, that’s my focus. I honestly couldn’t care less if it’s here on the last race, as long as it’s done."
Hamilton also expected Ferrari to bring some sort of upgrade to Austin.
"They’ve definitely had a couple of hiccups but I anticipate they’ll be very strong this weekend and for the last four races - so that’s why nothing changes for me," he added.
