Romain Grosjean on Haas, their first US GP and his infamous radio rants

As Haas get ready for their first race on home soil, Romain Grosjean spoke to Sky F1's Ted Kravitz about the team's debut season, radio rants, and his Formula 1 hopes for the future.

It's been a roller-coaster campaign for both the French driver and American outfit, with 22 of their 28 points scored in 2016's first four grands prix. In fact, Grosjean has yet to finish in the top 10 since July's Austrian GP, nine races ago.

"Those two first races were amazing," Grosjean says, referencing the season-opening performances in Australia and Bahrain. "We got everything right and it was beginner's luck. Then we had to learn Formula 1 the hard way.

"I don't know why were so good earlier in the season and I wish it would have continued, but it wouldn't have been normal to come to Formula 1 and finish fifth every weekend."

The former Lotus driver's recent struggles have perhaps captured viewers' attention even more thanks to his radio rants, declaring that the car was the "worst I have driven" during a Singapore GP practice session.

But Grosjean, who says Haas switched their attention to 2017's rules overhaul "very early", sought to clarify that the outbursts were down to his passion, and claims he has more of a Latin personality than that of a Scandinavian.

When's the US GP on Sky F1?

"I wasn't completely crazy," he explains. "When I was in the car it was not doing what it was supposed to do. I'm trying to push it to the limit all the time and I want the same from everyone.

"We don't have a microphone on the football pitch, on the tennis court, and I'm passionate about Formula 1. They know me, I think the atmosphere in the team is really good. They know the only thing I want is to be successful in the car. 

"I accept it, I take the blame. I just want us to be better than what we're doing."

Grosjean visited the Stewart-Haas NASCAR base in Charlotte ahead of this weekend's US Grand Prix, and it's clear it's a nation he now holds close to his heart. The 29-year-old once again confessed that he'd love to compete in the US' most popular motorsport in the future, while believes there should be another F1 race in the country on top of Austin.

Team owner Gene Haas, meanwhile, is delighted to have retained the man who will celebrate his 100th grand prix start this weekend for another year at least.

But how can Haas and Grosjean built on their mixed season, and will the American dream continue?

"I think that's what people forget, it's only our first year in Formula 1," Grosjean adds. "It looks like we have been here a long time but it's the first US Grand Prix for the team. I'm looking forward to it to see how the fans are reacting."
