The Grove team still does not have a spare, as Sargeant is using the chassis that was crashed by Alex Albon in Melbourne and subsequently repaired.
Sargeant lost control when he put his right-hand wheels on the grass at the high-speed Dunlop Curve lefthander, striking the barrier with both ends of the car. The accident and damage left the team not enough time to repair his car in time for FP2 and the American missed the entire session.
"It's pretty significant," said Vowles, when asked about the extent of the damage. "The chassis is okay, fortunately, but I would say pretty much everything else isn't. So suspension all round, gearbox cracked, big damage.
"It's going to be difficult. We'll obviously do our utmost to try and get the car back out there again, but the damage is extensive. So it will take a while."
Regarding Sargeant's mistake he added: "It's at the top of the brow of the hill there, he struggled to see where his positioning was on track. It fundamentally looks like he didn't quite realise where he was, with where the grass was on the outside, and put a wheel on the grass."
