Double world champion Fernando Alonso believes the new Ferrari F10 is the best car he has driven and says the team were hiding their true potential in last week's Jerez test.
"As of today, this is the best car I've ever had," the Spaniard, who won the world title in 2005 and 2006 with Renault, told reporters after the penultimate pre-season test ended on Saturday.
"Red Bull, McLaren and Renault have been very quick and have shown their cards, while we are still hiding ours," he said.
"We will analyse the data, but we are very optimistic. As of today, if I were in a different team I would be looking at Ferrari because everything is going really well.
"Maybe where Ferrari has to improve is the short runs with little fuel onboard."
Ferrari, fourth last year, recruited Alonso to replace Kimi Raikkonen and partner Felipe Massa this season.
The final test takes place at Barcelona next week before the season-opening race in Bahrain on March 14.
