Haas team principal Guenther Steiner confirmed the team has made changes to the design of its fuel hatch as a result of the fire which occurred when Romain Grosjean crashed in last year’s Bahrain Grand Prix.
As RaceFans revealed last month, examination of how Grosjean’s car behaved in the crash has led some teams to make changes to the fuel hatch and headrest.
Steiner explained the changes Haas has made in response to a question from RaceFans today.
“I think the biggest one is the fuel hatch cannot be attached to the chassis anymore,” he said. “And we are working on the headrest to make it smaller. The headrest is still there, but in parts, so it cannot get stuck there when it comes off.”
Haas is believed to be one of several teams which have altered their fuel hatches, despite the regulations defining their construction remaining unchanged.
“We changed because we think it is better to do it a different way,” he said. “You always learn out of these situations.
“Everything was within the regulations of what happened. There was nothing wrong with our car. It was just that it never happened before. What happened was a very strange incident, to rip off half of the chassis at the back.
“If there is a better solution we should try to adapt them all the time, you always need to stay up with the times.”
