Romain Grosjean completed 96 laps of the Circuit de Barcelona-Catalunya on Wednesday despite the Haas F1 Team driver losing around ninety minutes due to an exhaust issue.
The Frenchman was denied the opportunity to break through the 100-lap barrier due to a couple of late red flags, but he was able to do the majority of the planned programme as they continue to work on the strengths and weaknesses of the VF-17.
Grosjean has just one more day in the car on Friday – team-mate Kevin Magnussen will be driving on Thursday – to develop the car still further, feeling that just small adjustments should be enough to have a decent set-up for the first race of the season in Australia at the end of the month.
“It was a good day in the car,” said Grosjean. “We did most of the program we wanted to do. We’re still evaluating how the car is going and how we can improve the set-up and find the weaknesses and strengths.
“Hopefully, before Melbourne we’ll have the time to make some small adjustments aerodynamically and mechanically to get there and be ready for a good performance. I’m very much looking forward to getting back in on Friday.”
