While in the shop signing his final contract papers Grosjean tried sitting the No. 41 Haas Automation Chevy Sprint Cup car.
Could NASCAR be in the Frenchman's future?
"Could be, could be," Grosjean told Motorsport.com with a smile. "I sat in one of them yesterday. I was surprised there was so much room on the right-hand side. I was thinking, 'I'm not sitting in the middle of the car'. But we may give it a go. I think it would be really cool."
"He wanted to see what it felt like and he got right in," Haas said. "We don't have any problem with him driving a Cup car if he wants to. Maybe we will have an opportunity where he can try him out and see how he does."
