Felipe Massa has insisted that Williams will be able to rival Ferrari's pace at this weekend's Austrian Grand Prix after a series of upgrades.
Valtteri Bottas secured the team's first podium of the season at the Canadian Grand Prix last time out, while Williams' only pole position in 2014 came at the Red Bull Ring for Massa.
The Brazilian told Autosport: "Looking at the upgrades on the [Ferrari] engine, the difference [to Mercedes] is still similar and I think it shows that we can still fight at the front.
"I think the team is going in a good line. It's an important moment for us, we have a good track for us in Austria with some upgrades.
"So I think it's an important moment for us to put some pressure on Ferrari. I don't know when Mercedes will put some upgrades on the engine maybe when they do we can get stronger in that area."
Bottas was also on the podium in Austria last year, while Massa finished fourth, despite starting from the front row.
