Manor Marussia pair Will Stevens and Roberto Merhi remain hopeful that the squad could spring a surprise at the Austrian Grand Prix, with wet weather anticipated at select points across the remainder of the weekend.
The pair occupied 19th and 20th positions in the second practice session, though Stevens was able to set a time within six tenths of compatriot Jenson Button.
"Overall it’s been a good start to the weekend and I’m feeling quite positive," said Stevens. "We’ve done some good work with our programme today and our long and short run pace seems good here versus the cars around us.
"We’re in a good place compared to the McLarens ahead. The weather looks a little unpredictable, and if we manage to miss the rain, it will certainly be cool and cloudy for the next couple of days.
"I think we can do a good job here so we’ll have our heads down tonight to look at what we need to do from here."
Merhi finished significantly adrift of Stevens after a turbo problem restricted him to just 11 laps in the second session.
"I lost a bit of track time today with a small issue, so I haven’t had a completely smooth day and I think this is reflected in the lap time," said Merhi.
"The afternoon was a bit more straightforward and the pace was starting to come towards the end of the session, so I’m sure we can continue to improve tomorrow morning in preparation for qualifying."
