Haas forced to remove its T-wing in Australian Grand Prix practice

Haas was forced to remove its T-wing from its Formula One car ahead of second practice for the Australian Grand Prix, team principal Guenther Steiner has confirmed.

The FIA ordered it to be removed before the second session after television footage showed the device -- run on both the VF-17s of Romain Grosjean and Kevin Magnussen -- flexing significantly on several occasions during the first practice session of the 2017 season in Melbourne. Steiner said he is unsure whether Haas will be allowed to run its version of the T-wing over the rest of the weekend.

"We ran this wing in the whole Barcelona test and never had a problem with it breaking or anything," Steiner explained. "In FP2 we had to take it off because of the moving, so we need to see what we do in FP3.

"On the data we can see the downforce is there. It is working, so we want to get it back on. But we need to see if we're allowed to. On this racing car everything is so to the edge, everything helps -- and you want to keep it on."

The American outfit, which is looking to improve on the eighth-place finish it recorded in the constructors' standings during its debut season in 2016, showed promising performance as Grosjean ended up eighth quickest in both sessions. Steiner played down the Frenchman's practice form, maintaining his belief that the midfield pack is simply too close to call.

"This morning his lap was the best one he did. This afternoon we were a few tenths off on his fastest laps. It's good, but it's so close as I continue to say. I think I'm annoying people. You can end up eighth, you can end up 15th or 16th."

It was not such a smooth day in the other side of the Haas garage with Magnussen only managing the 17th best time in the morning, before a water leak in the afternoon restricted the Dane's running to just 8 laps as he finished 19th.

When asked about his day, Magnussen replied: "I didn't really get much out of it. We'll investigate and, hopefully, find the issue. It's good to see, though, that the car is competitive. That's the positive to take from today."
