Sebastian Vettel believes that the curve strength of the Ferrari Formula 1 racing car in 2019 has cost straight-line speed, but more data is needed.
One of the main features of the Ferrari last season was a strong top speed performance. Vettel and Charles Leclerc seemed to be struggling in this area at the Australian Grand Prix.
Red Bull Motorsports Adviser Helmut Marko hinted this week that it could be a mix of Ferrari retreating due to cooling problems and being held back by closed engine gaps for 2019.
Asked by Autosport Whether Ferrari had lost its speed advantage, Vettel said: "We have lost everywhere, if I say anywhere, that also means on the straights."
"I would not draw too much conclusion. Last year we had a very efficient car, and maybe at the end of the year we were a bit small in terms of downforce, so you could be faster on the straights.
I think this year's car, when it gives us the feeling of being a very strong car, is very fast around the corners, maybe it's a bit slower on the straights.
"But I do not think I've had enough time to race to really give a fair answer."
Vettel escaped a question from Autosport about Marko's claim that Ferrari had a cooling problem and fueled in Melbourne had to save.
It always depends on where you are compared to others, "he said. But I do not think we are in a different ball game than others. "
" After the race we had some laughs on the plane.
"Helmut was sleeping, so I'm not sure where he did his analysis!"
Vettel ended more than a minute behind Mercedes I by Valtteri Bottas in Australia, where Ferrari was far less competitive than the pre-season test.
Ferrari made "corrections" before this year's Bahrain GP, based on what he had learned from a difficult opening weekend, but Vettel said the "answers" may only be helpful in giving "answers".
"The key factor for me is that in the winter I drove a car that I really liked and felt really good in. It did what I wanted, I did not have much complain or complain – and we went to Australia and it was not there, "he said.
" We have some answers to the lack of performance for Australia, but we're not going back to Australia. "
He added, "We will never get the real answer because you will not return until next year."
"There are always some lessons – some dealing with the other ones were about configuring [circuit].
"They throw everything in the mix and we have reason to believe that we should be stronger here, but I do not want to give a number."  "Mercedes was more competitive than we expected, along with the fact that we were less competitive than expected, which explains the big difference."
