Daniel Ricciardo hopes Williams showed the best that they had to offer in Spain on Tuesday, a day where Felipe Massa beat the Aussie to the top of the timesheets.
Massa posted a 1:19.726 around the Circuit de Catalunya on Tuesday as the second of the two pre-season tests got underway.
That time handed him the day’s P1 by 0.174s ahead of Ricciardo.
And while Ricciardo says there is still more to come from Red Bull, he is hoping that Williams have shown their hand.
“At the moment there is no big secret or anything,” he said.
“We are not holding 2 seconds in our pocket, but we definitely feel that we can still get more out of the car.
“But I think probably everyone can.
“Hopefully not Williams – hopefully that was their best today.
“I think Ferrari and Mercedes can still get more out of theirs.
“So once that all happens we will see.”
Like many of his main rivals, Ricciardo was drawn to Ferrari’s form, which he reckons is looking really good.
Thrown in Mercedes’ pace as well as Williams’, and the Red Bull driver believes Formula 1 could be in for an exciting Australian GP.
“They [Ferrari] certainly look quick,” he said. “I am sure Mercedes will still be very quick. But Ferrari are looking good.
“Even though Williams did not run much last week, the day they did get a good run in, I actually thought they looked quite good as well and today they showed that.
“It is going to be interesting, Melbourne will be a nice little story.”
