Romain Grosjean was delighted to finish best of the rest in Austria and thinks there will be more to come next week at Silverstone.
The Haas driver has had plenty of issues with his car this season, but was the last to finish on the lead lap in Spielberg and came home in P6.
Grosjean was also right in the thick of the action at the start, trying to take on the likes of Kimi Raikkonen in the opening stages.
"It was really good, really strong first half when I was P4,” said Grosjean. “A fun few laps, like 2013. I could play with the car in front and make some good positions.
“Obviously there was no chance to keep Kimi and Lewis behind but I had a great fight with Perez. He was pretty fast and we had to push all the time. The car behaved well.
“We were best of the rest – so we won Formula 1 Grand Prix 2!”
Grosjean reckons the American outfit are finally learning where the optimum window is with their car and is hopeful that there is more improvement to come at the British Grand Prix.
“There are a few things we need to improve but when we get the tyres to work and the right downforce level and the right drag level we are very competitive,” he added.
“It shows that when we get everything to work on the car, we are strong. It’s just the experience, because everything is a window, which we are missing a bit sometimes. But it’s only our 28th or 29th race.
“We should have an update for Silverstone, so that should be good fun.”
