Romain Grosjean is hopeful that warmer weather across the upcoming sequence of Formula 1 events will boost Haas, after recent struggles in getting tyres into the right operation range.
Grosjean scored points in three of the first four Grands Prix but has not added to his tally since, believing that cool conditions hurt Haas' ability to get the maximum out of its VF-16.
Grosjean was on course to challenge for points at a warm European Grand Prix until he required an unscheduled extra pit stop, and is confident that Haas can soon return to the top 10.
"I’m hoping that we get a good summer and that we don’t have to focus too much on colder weather and trying to get the tyres to work," he said.
"It was a shame about the race in Baku that we had to have the extra pit stop. I think we could have scored points. We were looking pretty good up until that point. Some of the races we’re now going to should be better for us.
"We still need to work on getting the best out of the tyres when it’s cold. We have some graining issues as well, but we’re still a brand new team and we haven’t had many options to try different things.
"We’re going in a good direction even though we haven’t scored points in a while. I still think everything is going the way it should and when it eventually all comes together, it’s going to be great."
