Felipe Massa, Ferrari, Jerez testing 2013Felipe Massa says Ferrari is on a "different planet" compared to the difficult situation it found itself in during pre-season Formula 1 testing last year, after getting his first impressions of the new F138 at Jerez on Tuesday.

The Brazilian ended the day sixth fastest, but was not too worried about the lap times, because most importantly Ferrari had banished the prospect of a repeat of 2012's opening test nightmare.

"I think if you compare to last year it is a completely different planet," said Massa, when asked about how his first day's running with the new car compared to 12 months ago. "Last year, I remember we were struggling a lot to drive the car. It was tricky to keep the car on the track, so this year the base on the car is completely different to last year.

"The car is much more balanced. I felt a good direction on the rear of the car as well, with traction. This is a track that is very difficult on the rear, degradation is very high. I would say that the difference to last year is huge."

Massa said early issues with the F138 have cropped up – like the need to improve cooling in the cockpit – but there were no alarm bells ringing about significant performance problems.

Felipe Massa, Ferrari, Jerez testing 2013"I don't think it is a difficult thing to fix," he said. "I am not disappointed, definitely.

"The 1m18.8s [lap time of Jenson Button] is an incredible time, but the 1m19.7s [of second-fastest Mark Webber] I don't think is.

"There is a lot to do, a lot to work on, a lot to develop on the car for the first race. That is clear. But I am not disappointed."
