Fernando Alonso says McLaren's focus is on improving reliability after neither he nor team-mate Jenson Button reached the finish in Canada.
Alonso's retirement was his fourth from six starts in 2015, while stand-in Kevin Magnussen also encountered a problem during his sole event in Australia, which prevented him from even reaching the grid.
"We’re still seeing great progress every weekend, and we hope Austria will be the same," said Alonso, ahead of this weekend's race at the Red Bull Ring.
"Our most important focus is reliability, so that we can get the most time on track in order to make the biggest improvements we can.
"This is a very physical circuit with four long, fast straights and heavy braking in the corners, so it’ll be challenging for our package, but it’s a really interesting track to race on."
Button added that McLaren has already got over its Canada woes.
"Over the past few days we’ve bounced back from Montreal and we’re already looking firmly ahead at the next challenge," he said.
"As a team, we’re measured ultimately on where we finish on a Sunday afternoon, which doesn’t take into account the progress we’ve made behind the scenes, or in practice and qualifying in the build-up to the race, so it can sometimes be difficult to see the positives after a tough Grand Prix."
