Carlos Sainz Jr. was left to rue changed conditions which scuppered his progress during qualifying for the Hungarian Grand Prix.
Sainz had emerged as a top 10 contender throughout practice and placed fifth in the final session on Saturday morning.
However, Sainz slipped back in qualifying and, having been unable to progress from Q2, will start from 12th place on the grid.
"I had been quite comfortable with the car the whole weekend, we were looking strong," he said.
"However, in today’s qualifying session the conditions changed, as well as the feeling with the car, especially with the brakes, compared to yesterday.
"All this made me lose my references and I just couldn’t get into a rhythm, so unfortunately I struggled to put a qualifying lap together. We really didn’t expect to find ourselves in this position as we knew we had the potential to make it into the top 10."
Sainz is remaining optimistic, citing his drive from the pit lane to the top 10 in Monaco as his inspiration.
"We need to analyse this and focus on tomorrow’s race," he said.
"It’s not the easiest of tracks to overtake, but we said the same about Monaco and I was able to finish in the points after having started from the pit-lane, so anything is possible tomorrow and we will fight as hard as possible for more point."
