Fernando Alonso has updated his cautious appraisal of Ferrari's new car by admitting it feels better than his 2009 mount.

The Spaniard has switched to the famous Italian team from Renault, the scene of his back to back title wins of 2005 and 2006.

Renault endured an awful 2009, suffering the spiralling consequences of the crashgate scandal and finishing the constructors' championship eighth of the ten teams with its R29 car.

But 2009 was also a season to forget for Ferrari.

Alonso, 28, was cautious about assessing the new F10 when he drove it recently at Valencia and Jerez.

But he admitted to France's Auto Hebdo: "I felt the differences between it and the 2009 Renault.

"There was obviously more downforce!" Alonso is quoted as enthusing.

"But I am not going to say now that it is capable of fighting for victories and the world title.

"Before the first race, everyone is optimistic and I'd rather wait a bit.

"The new rules are in their second year, the double or now triple diffusers have become widespread, and I want to see what the others have done," he added.
