Esteban Gutierrez says that completing a race simulation on his second day in the Haas VF-16 was 'very useful' for Formula 1's new team, as the outfit racked up further mileage.
Gutierrez, who finished the day in 10th spot, focused on race simulation work early in the afternoon session, completing a long stint in a Formula 1 car for the first time since his Sauber departure at the end of 2014.
Gutierrez explained that completing the race distance will aid the nascent team as it seeks to iron out any early issues.
"It was good, very nice to be back on a race distance, to be able to experience it, to get a proper feeling and to take the car to the limits as this the only way you can understand how far the car can go in terms of reliability," he said.
"So it was very useful for the whole team to have this amount of data and laps, ideally we would do more but from the position we found ourselves at the beginning of the test as a new team this is what we can expect.
"We found some issues, but these are not big ones, so I'm confident next week we will be in a good shape to explore the performance of the car."
Gutierrez added that he had braced himself for Haas to suffer more problems over the course of the first test.
"I was mentally prepared to be very patient, I think the team has done a very good job, reacting very quickly to everything we had," he said.
"It’s not easy for a new group of people, who on one side don’t have experience and others who have a lot of experience, it’s been useful for the team to get to know each other.
"It will be important to sit down over the weekend and analyse ourselves and to get ready for next week and to consolidate ourselves in preparation for Melbourne."
