Ferrari driver Fernando Alonso says the team still expects to fight for the Formula One title this season despite acknowledging the scarlet cars are likely to struggle in the season-opening Australian Grand Prix this weekend.

Alonso said Thursday that this year's car is still not a finished product heading into Friday's first practice session and that the team is behind the likes of Red Bull and McLaren in development.

However the Spaniard said the legions of Ferrari fans should not give up hope quite yet.

"We are not 100 percent, there is more to come from this car and it will come hopefully soon," Alonso said. "The team is very, very motivated for the championship, very ambitious, all the members of the team.

"Maybe we are not as quick as other teams in this race, but we want to be champions in November," he added. "This is like the Tour de France. There are 20 stages and this is the prologue, the time trial stage."

When Alonso made the switch from Renault - where he won two world championships - to Ferrari it was with the expectation of joining a dominant outfit, but after a competitive 2010 in which he went to the last race still in the title fight, the team was well off the pace in 2011.

Last year the team was uncompetitive from the start, and won only one race for the season. Alonso needs no reminding of the team's struggles in the early stages of a season, saying: "I am used to hard starts to the season, unfortunately."

Ferrari's anticipated poor start to this season is a result of the team totally overhauling the disappointing 2011 car, while the likes of Red Bull and McLaren had the luxury of making relatively minor adjustments to their strong cars from the tail end of last season.

"Six days of testing are not enough to change black to white," Alonso said. "Its not a continuation of last year's car, so we need more time than other teams to maximize the car. We will see how competitive we are when we drive in qualifying here in Melbourne, Malaysia and China.

"Sooner or later Ferrari will win races. If we have a slow start its doesn't matter, and that is the good thing about Ferrari."

The man to beat this coming Sunday, and in the season ahead, is Red Bull's Sebastian Vettel, who comfortably won last year's title to add to the 2010 crown. This weekend he will embark on his quest to become only the third man to win a hat trick of championships, after Juan Manuel Fangio and Michael Schumacher.

"I am here to win the championship, that is the target," Vettel said Thursday. "Whether its the third or not does not make a difference."
