Toto Wolff believes the pace Williams showed at the Austrian Grand Prix was not a one-off and could translate to upcoming races too.

While Williams has had a strong car since the start of the season it has struggled to put together a complete race weekend and Sunday's result - where Valtteri Bottas finished third behind the two Mercedes' - was the team's first podium of the year. With Williams locking out the front row and getting closer to Mercedes in the race than any other team has this season, Wolff said the circuit hadn't appeared to suit its rivals all that much.

"It's interesting because if we would have discussed before the race weekend who was going to be a favourite for the track you would have said OK definitely power unit in the first sector - up the hill it is pretty steep - but that second and third sector is an aero track," Wolff said. "And the teams out in front were different from what we expected before the weekend.

"I think Williams had a very strong recovery this time. Formula One is all about maintaining the development curve and learning what functioned and what didn't. And hopefully they are able to come back again to another solid result in Silverstone."

Although Nico Rosberg won in Austria, Wolff was impressed by how hard Williams was able to push Mercedes and said the performance appeared to show a genuine step forward.

"Honestly I'm happy to see how they performed, because at the beginning [of the race] their pace was really impressive. Not only in the first sector - they six or seven kph more on the straights - you could see how Valtteri passed Nico after the start and then you say 'OK if you have a car that is less draggy then it should be suffering in the downforce parts', but it didn't. The second sector and third sector was quite impressive as well, so I think they've just done a good job."
