The day was Brown’s second run with the Commodore, and he said a plan for Alonso to follow sportscar driver Filipe Albuquerque behind the wheel was thwarted because “we ran out of petrol”.
“It was his first day in the LMP2 car,” Brown explained.
“It was one of these 'if we had time at the end of the day to do a lap, I'd love to do a lap' and we ran out of petrol.
“Actually, Felipe Albuquerque was in the car when it ran out going down the back straight. If we would've had time he would've had a go.”
Asked if Alonso sat in the car beforehand, Brown said: “No, Fernando, he was in a very strict mindset.
“It's kind of 'I've looked at it, I've looked around it, now let me go do my job [in the LMP2 car] and at the end of the day when I'm out of that mode, if we've got time, I'll go have a play' but we ran out of time - and gas.
