Williams drivers Valtteri Bottas and Felipe Massa say they have been encouraged by the long run pace of the FW37 during practice for this weekend's Austrian Grand Prix.
Williams had several new upgrades to its car during Friday practice and the squad focused on long runs, with Bottas and Massa not troubling the overall top 10 times across the course of the second session.
"Our main aim today was to put the new parts we have through their paces and they all seem to be working as expected, which is encouraging," said Bottas, who claimed his maiden Formula 1 podium at the circuit in 2014.
"We have high targets for this weekend and we are still on course to meet these. The long run looks really positive and seem to be closer to the front than we have been previously."
Massa was nonetheless wary that Williams still faces an uphill challenge to compete with rivals Mercedes and Ferrari.
"We have had a good day with a lot going on in terms of changes to the set-up," he said.
"We had a slight issue when we went out to set our fastest laps, but we have corrected these and feel comfortable moving forward. The long run looks strong but we have two very quick cars in front so it still won’t be an easy weekend."
