Haas says rivals' Ferrari F1 allegations 'based on no facts'

McLaren and Force India have both expressed suspicions about the team's surge in form since last year, while conceding that there is no hard evidence of any wrongdoing.

Steiner says those making allegations have no facts on which to base them, and that everything the team has done has been clear with the FIA.

"Everybody is allowed to have an opinion," said Steiner. "Some people have an opinion, which I think is based on no facts. It does not have a lot of value to me.

"The whole of Haas can be proud of the work done between last year and over the winter to produce the VF-18 and get it into its competitive condition.

"It's merit to them. They can be proud. If people have an issue, fine with me.

"We report what we are doing, like everybody else, to the FIA. That's why I'm more than confident we are not doing anything wrong.

"I'm perfectly fine with how we do business. We design our own aero, as per the regulations, and yes, we use mechanical parts from Ferrari, but everybody's known that for the past two years.

"We are well above board, and happy to be where we are."

Haas's chances of scoring a major result in Australia ultimately unravelled with problematic pitstops for both Romain Grosjean and Kevin Magnussen, and Steiner hopes the team can quickly bounce back to avoid dwelling on the disappointment of the season opener.

"If we achieve a good result in Bahrain, we will forget about Melbourne," he said.

"If we don't, we'll dwell over what happened in Australia until the time we have a fantastic result, or time gets us over it.

"The aim is to do everything right and come home with a good result.

"I would say I'm still cautiously optimistic. I would never be arrogant and say, 'Oh we will do the same in Bahrain,' but we will try to do the same.

"The car showed speed in Barcelona and Melbourne. There is a point, maybe after China [round three], where we will really know where we are."

Both Haas drivers agreed that Bahrain will give the team a chance to bounce back.

"A good result will help us to forget Australia," said Grosjean. "Let's get to Bahrain, let's do our work, like we did in Australia, focus on our jobs and see where we are at the end.

"Hopefully, we can have another good surprise."

Magnussen added: "It would be great to have a good result in Bahrain after such big disappointment in Australia.

"We've got to start building points, as we've fallen behind. We've got to catch up."
