Ferrari's sporting director Diego Ioverno has said that the "bumpiness" of the Austin track, as well as the sprint weekend format, were what led to Charles Leclerc's disqualification from the United States Grand Prix.
Now, Ioverno has revealed in a video on Ferrari's official X, formerly known as Twitter, page how exactly the disqualification came about.
"What happened? It happened that technical regulations clearly state that, at the end of the race, there are some measurements that have to be respected for the bottom parts of the car, parts of the car that are used to protect the car from grabbing asphalt," he said.
"At the end of the race measurement, our car was below the minimum threshold for a few tenths, but enough to bring the stewards to consider illegal our position."
Ioverno: Weekend 'very peculiar'
With the US GP being a sprint weekend, teams only had one practice session on Friday before jumping straight into qualifying, and then a jam-packed Saturday and Sunday schedule.
Now, Ioverno has said that this was also the case for Ferrari, who were caught out by needing to make changes to Leclerc's car.
"The sprint weekend is very peculiar, you have very little time to prepare the car," he added.
"Basically only one session in FP1, and then you go into parc ferme meaning, from that moment onwards, you cannot touch the car any longer.
"On top of this, Austin is a super nice track but is extremely bumpy. Bumpiness is a difficult topic for drivers and for cars, in the past more or less everyone failed the suspensions, failed the chassis.
"We knew it would have been tricky, and this is the reason why we also lifted the car throughout FP1, and from our consideration, it should have been OK.
"As a matter of fact, it turned out we were, anyhow, too marginal, and also because of the wind which changed direction and had a stronger intensity than what was forecasted. This brought our car to not the legal at the end."
