McLaren Racing Director Eric Boullier is sure that his squad has "turned the corner" after securing a double points finish at the Russian Grand Prix.
McLaren endured a dismal 2015 campaign but made progress across the course of the winter, with Stoffel Vandoorne collecting the team's first point in Bahrain.
Further issues for Fernando Alonso and Jenson Button restricted the pair from scoring points until Russia, where Alonso collected sixth place and Button rounded out the top 10.
"A double points finish is a great result for the entire team, and a real marker of the progress we’ve been steadily making since the start of the season," said Boullier.
"Fernando drove a brilliant race, displaying all the guile, aggression and opportunism for which he is so well known. Sixth was a great reward for his efforts.
"While we know that one swallow does not make a summer, we stand firm in our belief that we have turned the corner and will start to make further progress throughout the season."
Honda chief Yusuke Hasegawa expressed "relief" over McLaren's haul of points.
"We knew that our longer stints were good here, but it was a job well done for our team and drivers to manage our one-stop strategy and fuel-saving during the race, which led to the results," he said.
"We know that we still have a long way to go, but I’m relieved that we’ve finally confirmed that we have the true potential to fight within the middle of the pack."
