Romain Grosjean has admitted that switching to Haas for 2016 moved him one step closer to a "dream" Ferrari seat.

To the surprise of many, the Frenchman turned down the opportunity to ride the transition of Lotus into the Renault works team in order to instead join Formula 1's newest outfit.

"We will get the first idea about whether I was wrong or not here," the 29-year-old told RMC ahead of the Melbourne season opener.

"I'm not somebody who looks back - I made a choice and I will not have regrets.

"Overall, I'm happy with my choice and I feel so welcome at Haas. I know there will be difficult times because we are a new team but I hope we will also have a great time and keep our smiles."

Haas has sided strongly with Ferrari for its new project, to the extent that many are saying it is effectively the Maranello marque's 'B' operation.

"Haas established a very intelligent technical partnership with Ferrari," Grosjean admits. "Mercedes did the same with Manor.

"If we have a problem, Ferrari will react quickly. This is something that motivated me to join the team. We should have fewer problems than other new teams that arrived in F1."

The new season kicks off with the Australian Grand Prix on Sunday.
