Williams have admitted that there are ‘question marks’ over whether they’ll be able to run on the final day of this week’s test at Barcelona following Lance Stroll’s accident on Wednesday.

Stroll hit the barriers exiting Turn 5 in the afternoon session, damaging the front and left-hand side of his FW40, just hours after new parts had been flown in from the UK by private jet following a separate off by the Canadian rookie on Tuesday.

“We’re still assessing all of the damage,” Williams’ Head of Performance Engineering Rob Smedley told reporters. “There was a little bit of damage to the left-hand side of the car, so we’re still having a look at it.

“Honestly I can’t make a full judgement call on what has been damaged and what the contingency will be from this point onwards until we’ve had a little more time to think about it.

“There’s a question mark [over whether we’ll run on Thursday] but obviously we’ll be doing our utmost to get out – it’s a really important day of testing for us. We had a good day learning about the car and obviously we’re desperate to continue that for tomorrow onwards. So our aim is to get the car out.”
