Lando Norris says an unexpected anti-stall moment cost him the chance of scoring points during Saturday's F1 Sprint in Austria.
The Briton had qualified third for the Sprint behind Max Verstappen and Sergio Perez, but dropped down to 10th by the end of Lap 1.
It had appeared as if Norris had been baulked by the duelling Red Bulls ahead of him at Turn 3 on a slippery track, but the McLaren driver revealed afterwards that his car had inadvertently gone into anti-stall.
"We both went quite deep into the corner," Norris told media, including RacingNews365.com.
"Max wasn't backing out for Sergio. I was maybe hoping for something to happen, but I wasn't expecting anything.
"I lost the rear as I turned into the corner because the tyres were cold, and it's a bit difficult to get the Inters to work straight away.
"I lost the rear, slid further up the track almost into them, and to avoid that I had to hit the brakes again, and at such a slow speed with basically zero grip, I locked the rear tyres quite a bit and got into the anti-stall.
"I think it was just unlucky at the time. I didn't feel like I went in too hard. I didn't feel like I overshot. I just turned in, lost the rear, cold tyres, first lap. It's just how it happens sometimes."

Anti-stall 'cost me the race'
Norris would eventually finish the Sprint in ninth place, and added that his Lap 1 mishap had ruined his chances of scoring any points.
"Unfortunate, because it cost me the rest of the race," Norris said.
"It cost me the chance to score some good points and probably fight the Astons throughout the race.
"I was hoping something happened, but I wasn't really expecting much. I knew they would probably pass me again within a corner."
