Grosjean to use floor from winter testing in Abu Dhabi

With his Haas team's campaign having been hurt by an update it brought to the Spanish Grand Prix not working as expected, the Frenchman and his teammate Kevin Magnussen have recently gone back to a similar specification of car that they had at the beginning of the campaign.

Speaking ahead of the season finale at the Yas Marina circuit, Grosjean has revealed that he is down to use the very same floor that he first ran in winter testing at Barcelona in Spain back in February.

"The funny story is that what I race here will be floor V1, number one, which is the floor that we had in winter testing," he told Motorsport.com.

"I guess maybe it's never been done in F1 that you actually go to the last race and you actually bring the same thing you started with."

Asked if it was a bit weird in the fast-changing world of F1 that he would be competing in the last race with pretty much the same car he started it with, Grosjean said: "It is the best one we have. But yeah, especially on a new regulation, it is strange."

The Haas team is well aware of the mistake it made this year in not getting on top of what went wrong with the update quick enough, and that it especially should have listened to driver complaints faster.

But Grosjean said that lessons have been learned and there is no point thinking about what could have been if things had been done differently.

"It was very clear from Barcelona that I just didn't want to run the new package and I felt it was less good, and we could probably have saved some time if we had reverted back to the other spec," he said.

"But it's always easy afterwards to say things. If I knew what I know now, I would have bought a lot of Amazon [shares] when I was young in the stock market. Maybe even buy the company!"
