Romain Grosjean is aiming to get Haas into Q3 in qualifying for the first time this season and feels he has reason to be confident thanks to his single lap pace in practice.

The French driver says overall he enjoyed a progressive Friday practice and feels key set-up changes will enable him to find significant gains to edge ahead in the tight midfield battle emerging at the Hungaroring.

With half a second separating Fernando Alonso in seventh and Grosjean in 15th on the FP2 timesheet Grosjean feels a top ten slot is possible as he looks to battle back into the points having missed out at Silverstone.

"There is more to come tomorrow and I'm hoping for my first top 10 in qualifying, that would be nice tomorrow afternoon," Grosjean said. "We're going to do some set-up changes tonight to make the car even faster, but we have had a good day."

Grosjean - who did claim P9 on the grid for the Bahrain Grand Prix albeit in the heavily-criticised knockout qualifying format - couldn't enjoy the perfect day for Haas after its braking issues reappeared in the closing stages of the afternoon session.

The French driver has struggled with brake management and cooling in recent races, something Haas has been keen to resolve to sooth its driver's frustrations, but Grosjean says more work needs to be done.

"It's been a few races we've been struggling with the brakes," he said. "The first quali-style lap I was struggling with some front-locking, and the next push lap it was all over the place on rear-locking, I lost it into Turn 1 so I just need to understand to why.

"It's not easy to say, not easy to analyse. So far we've always done a great job and moved forward, so by tomorrow it should be sorted."
