Max Verstappen was unable to explain why he suffered from a lack of pace during Saturday's qualifying session for the British Grand Prix.
Verstappen had been comfortably inside the top 10 during practice sessions across the weekend but was vocal on the team radio about his ill-handling Toro Rosso STR10 before dropping out in Q2.
Verstappen will start the race at Silverstone from 13th position on the grid.
"To be honest, I don’t really know what happened in today’s qualifying session, because we’ve been really competitive during the whole weekend," he said.
"Then, as soon as I went into Q1, I suffered from oversteer and I was not happy with the balance, so in the end I just wasn’t able to put a lap together.
"We need to look into this and find out why this happened. It’s disappointing because I was really looking forward to this qualifying session, but the car wasn’t behaving how I wanted it to and I couldn’t improve.
"Hopefully we can do something before tomorrow, we showed good pace in the long runs so hopefully we can have a good race."
