While Felipe sat the overall fastest time during the four day Jerez test, Niki Lauda claims Red Bull the best new car.
Feb.11 (GMM) Felipe Massa, who clocked the fastest overall time at last week's Jerez test, has declared the Ferrari F138 "better" than its predecessor.
"It's more consistent, better in braking, in and out of the corners and easier to understand," he is quoted by Brazil's O Estado de S.Paulo newspaper.
The Italian team's experienced new test driver Pedro de la Rosa, who tried the 2013 car on Friday, agreed: "The car is well balanced and responds well to changes."
He told AS newspaper: "There are no problems, but until the end of the Barcelona tests it's absurd to draw any further conclusions."
"But the one we are testing is different to the car that will start the season," he added.
Lotus' Kimi Raikkonen was fastest as the Jerez test concluded on Friday.
But Niki Lauda - F1 legend, German-language commentator and new Mercedes chairman - thinks Red Bull has "the best" car after the first week of pre-season running.
"Ferrari is next and then Mercedes, but the differences are small.
"It will be another hotly contested championship."
