Stroll could only manage a P14 finish at the Red Bull Ring, and the Canadian has confirmed that it had a lot to do with some power unit issues that he had to manage for around 10 laps.
However, the Canadian driver has insisted he is unsure what happened to the team's engine: "It was definitely not our race today. The first stint looked promising and I was in the hunt behind (Nico) Hulkenberg and (Sergio) Perez, but then we had some power unit issues to manage for around 10 laps, which I think cost us five or six seconds.
"I'm not sure exactly what happened, but then we had an issue with the fuel flow meter, so we had to turn down the mode quite a bit, which cost us another pace to (Daniel) Ricciardo. So overall, a tough afternoon for sure, but our sights are set on Silverstone and looking forward to the team's home race."
