Ferrari is giving up on the 2013 F1 season because Red Bull seems unbeatable - which is not good news for the tifosi - perhaps now they'll boo their own team.BERLIN, Germany - Ferrari has all but thrown in the towel in the Formula 1 title race after the latest demonstration of strength by Red Bull's Sebastian Vettel.The team said it would now concentrate its efforts on developing a competitive car for 2014.Vettel's latest win on Sunday (Sept 22) in Singapore, a convincing 32 seconds ahead of Ferrari's Fernando Alonso, saw him increase his championship lead to 60 points en route to a fourth title - with six races left.'STRIVING HARD'Ferrari's team principal Stefano Domenicali said on Monday (Sept 23) that Ferrari would still aim to be ready to take advantage of any mishap by Vettel but that the team's focus was now shifting to 2014, which will see several major changes including a V6 turbo engine in place of the current V8."It's clear that 99% of our energies will be concentrated on the 2014 project, as complicated as it is important," Domenicali told Ferrari's website. "Ahead of the break we were striving hard for a performance gain in Singapore, on a track with characteristics particularly unsuitable for our car."Instead we lost even more ground, despite the F138 being improved in certain ways. We still have some new parts for the car that we will bring to the coming races but, above all, we will now try to make the most out of what we have."Acknowledging the superiority of Red Bull and Vettel, Domenicali called for an improved effort from everybody involved at Ferrari in 2014 when Kimi Raikkonen, the most recent driver to win the title for it in 2007, joins Alonso in place of Felipe Massa.CRITICAL OF BOOING FANS"I don't think for a minute that the people we have are less capable than those working in other teams," Domenicali added, "indeed, I'm convinced of the opposite. But it's a fact that the others have worked better than us and this must work as an incentive for us."Domenicali also criticised those who booed Vettel again at the Singapore victory ceremony - something which has become an issue in recent races. It has been suggested that they are Ferrari fans disgruntled by Vettel's frequent victories."I wasn't happy to hear that Vettel was booed under the Singapore podium as well. He was perfect and he was helped out by a car that as quick as it was reliable: this should be acknowledged."
