Sebastian Vettel says Ferrari’s 2019 Formula 1 car is not “as bad as it looks” despite failing to win a race during the opening six rounds of the season.

Vettel finished second behind Lewis Hamilton in the Monaco Grand Prix to deny Mercedes a sixth consecutive one-two finish, though it still managed to keep up its 100 percent victory record so far season.

The German has moved up to third in the drivers’ standings but is 55 points adrift of championship leader Hamilton, while Mercedes heads Ferrari by 118 points in the constructors’ championship.

“I saw that Valtteri [Bottas] was faster but there was no way he was going to pass, as our straight line speed is really good,” Vettel said.

“It’s just because overall we are lacking downforce, a weakness that we know. I don’t think the car is as bad as it looks. The results should be better here and there but it’s very difficult for us to get the car in the window where it is happy.

“Certainly when we get it in there we’re more competitive but still a way from where we want to be. That’s really the key lesson: we need to focus on trying to get the car short-term more in that window.

“Looking forward for the next three, four, five races, obviously make sure we improve the car, put more grip onto the car so that we can go faster, simple as that.

“But that guy seems to hide fairly well. I don’t know exactly where he is right now, so if you find him, or if you’ve got his number, that grip guy, but we’ve been looking for him for a while.

“I don’t think there are any secrets we will be able to unveil. As usual, attention to detail and a lot hard work is the only way to get us up.”

Vettel admitted he is yet to find his best form this season and insisted he cannot be excused from Ferrari’s failures so far in 2019.

“I’m part of the team so I don’t put myself above [it],” he explained.

“I’ve had some difficult moments this year where I’m fighting the car, I’m not really entering yet to the level where I feel a lot more comfortable and I feel comfortable to squeeze out more performance from the car.

“But I think it’s linked to the fact that we struggle to put our car in the right window. Once it is there, it is feeling better and you’re able to build up on that but it doesn’t happen very often but it’s a combination of things.

“I think first we are lacking overall performance and that overall performance would help us probably to put the tyres more often in the window they would like to be in.

“It’s not a secret, by now, after six races that these tyres this year seem a bit more critical to get exactly into that window.”
