In Miami, Team USA rolled out its first major upgrade of the season with a revised field format.

Kevin Magnussen surprisingly finished fourth, helped by problems from others and red flags in the third quarter.

The Dane got off to a poor start, and after doing his best to make it difficult for his opponents – notably Ferrari’s Charles Leclerc – he eventually finished 10th.

Meanwhile, his teammate Nico Hulkenberg dropped from 12th on the grid to 15th on the flagpole.

The changes in the new floor, which focus on the underside rather than the more pronounced edges, are an improvement, Steiner said.

However, he reiterated that the team must improve the car’s performance in traffic.

“It seemed to work,” he said of the floor. “We just have to find out what we need to do to make the traffic more stable, you don’t wear out the tires so much in traffic.

“Because these guys say, in traffic, they can see other cars that aren’t struggling as much as our car, so the people in the aviation department are going to work on that.”

He added: “We have some components for the Imola, some front wing flaps, not a full wing. And they’re still going on.”

Steiner pointed out that the Miami race highlighted how difficult it is for his drivers to follow other cars without losing tire performance.

“It’s very difficult to get points, in five games we have three points, which is not bad,” said Magnussen’s match Steiner.

“In the beginning, we were going pretty well. Once we got stuck in traffic or something, we would drop a little bit, we would go a little slower. We need to work on that and see what it is.

“But all in all, I think we can bring back some points when we get into the top 10. I mean, obviously, if everyone finishes the race, it’s going to be very difficult.

“Finally we did it, we got a point, that’s the point for this year, as little as you can have, let’s take it home, don’t leave anything on the way. As much as you want more, but We need to be happy with what we get.”

Steiner said he was delighted to see Magnussen take on Leclerc’s Ferrari.

“Fighting Leclerc at the start and stuff like that is pretty good,” he said, “I think everybody likes that, that’s what it’s supposed to do. It’s good.

“Just in the second half, after his second set of tire fights with Leclerc, things went downhill until he got his tires back on and then the rest of the guys behind him got new tyres.

“But I don’t think they end up being a real threat in the end. But you always worry that one little mistake and you’re going to lose the point there.”
