Former Formula 1 driver Max Chilton says he is surprised that Manor Marussia has lasted so long into 2015, following its revival at the start of the campaign.
Chilton joined the squad under its Marussia guise as a test driver in 2012 before graduating to a full-time race seat in 2013.
Chilton remained with the team in 2014 until it dropped off the grid following the Russian Grand Prix.
Chilton has since raced in Indy Lights in the United States, alongside his drive with Nissan [Nismo] in the World Endurance Championship.
"I wasn’t surprised [about Manor Marussia's return], but I’m surprised how long they’ve lasted," Chilton told F1i.
"I will still wait to see how long that will last. It was a bit of a shock but that was because we weren’t talking to them so I didn’t have a clue where they were positioned."
Chilton said that the squad did well to make it to the season-opening race in Australia, considering the problems which it had encountered.
"They did well to turn it around or at least get things together because I did see [team boss] John [Booth] at Silverstone in February, two weeks before Australia," he said.
"Nismo are based in the same building at Silverstone and they were organising things which you can’t believe they were still organising! But they got there to be fair."
