Sainz: Ferrari can recover F1 engine performance and bounce back

Ferrari endured one of its least competitive races in recent years at Spa last weekend, where Charles Leclerc and Sebastian Vettel qualified 13th and 14th respectively, reversing their positions within the race.

The lack of Ferrari's straightline performance that has been apparent all year was even more evident at Spa, with customer teams Alfa Romeo and Haas also suffering.

Sainz, who will replace Vettel at the team in 2021, acknowledges that Ferrari has a lot of work to do - but he says that Renault's successful efforts to improve its power unit in recent years show that it is possible to make progress.

"I think clearly Ferrari is the first one that is not happy right now," he said.

"And I think we could see clearly how much they struggled. But I think they struggled with a bit more than the engine, I think they also had some problems with the overall grip of the car.

"When you lose so much power from one year to the other, which is actually not the normal trend in F1, normally you are expecting to stay the same or gain, but when you lose so much power, you know that in Spa you're going to get in trouble.

"So I think it's an abnormality to see Ferrari so far back, but it's normal after what we saw in the first races how much they are losing on the straights."

Regarding the prospects of future recovery he said: "In general I would say that yes, they need a very big step on the engine coming.

"I know how tough it is, because it took Renault three years, and it's taken Honda quite a long time also.

"So the fact that Renault is nearly there, close to Mercedes, also shows that you can do it.

"And for me, if there's a team with facilities, if there's a team with resources, if there's a team with a lot of engine benches to try and improve, that's Ferrari.

"So I'm sure the factory now is working flat out, and hopefully by the time I get there, they've improved a bit.

"And then together we can do the next step."
