“It wasn’t a good day, I made too many mistakes with these track limits, [and it] cost me 15 seconds,” he admitted.
“So I can only be disappointed with myself because obviously, you’re talking a few centimetres, which is nothing.
“But I paid a big price for it and missed out on the points, so I’ve just got to learn from this.
Gasly had out-qualified team-mate Esteban Ocon by two-tenths as Alpine enjoyed a productive qualifying hour on Friday evening to haul two cars inside the top eight.
However, Gasly’s race began to unravel when he was caught flat-footed by the colliding Mercedes at Turn 1, dropping him behind Ocon and McLaren’s Lando Norris.
But the Frenchman has revealed he was also hampered by engine management problems throughout the race, which inspired him to take more risks with overtaking manoeuvres.
“All in all, it was a tough day. I had a good start but went on the outside and had to slow down with the Mercedes in front of me, so I lost another two positions,” he explained.
“And then after that the whole race we had an energy management issues, which cost me straight-line speed throughout the whole race. I tried to compensate for it and took too many risks, so [ultimately] not a good day from us.”
Gasly criticised the FIA’s handling of track limit infringements, claiming that any warnings were directed to him too late by the time they arrived from his engineer.
“It was the story of the whole race,” he bemoaned. “I don’t have any excuses because it’s the same for everyone, and at the end of the day, I took too many obviously.
“I don’t know how many track limits there have been the whole race, but we were always two steps behind from what’s happening, and I think it wasn’t an easy day for us.”
The extreme humidity present during Sunday’s race saw many drivers struggle, including Ocon – who admitted that he vomited in the early exchanges.
However, unlike Aston Martin’s Lance Stroll, Gasly has not attributed blame to the tough conditions for the spate of penalties he received for exceeding track limits.
“It was the toughest race of the year,” Gasly agreed. “It was clearly very hot in the car, and very physically challenging. I knew it would be like that.
“And I know I’m training really hard, and I have one of the best physical conditions in the paddock. So I usually embrace these conditions.
“And I know it’s challenging for everyone, but today I just didn’t do a good enough job, and I need to learn from this track limits story.”
