A bewildered Sebastian Vettel was at a loss to explain his struggles in Sunday's British Grand Prix, the Ferrari driver finishing a lowly 10th and over 20 seconds behind teammate Charles Leclerc.
Vettel never made any progress from his P10 starting position on the grid, running rather anonymously all afternoon in the second tier of the midfield.
The German driver said he never felt confident in his car but was hard pressed to understand why, suggesting that something just didn't add up.
"The car was very difficult to drive," he said. "I struggled a lot to find my confidence and I don't know why, so we need to have a good look.
"But certainly, you know if I struggled for so many laps in the race, and it was from the beginning to the end, then there's something that probably doesn't stack up.
"It was not a very stressful race. I just didn't have a chance. People around me were faster than me. I got overtaken. It was very difficult to manage myself to stay on track.
"Physically it was not a tough race at all because I could never attack the car. It didn't allow me to do what I like so.
"Now we need to have a look why and obviously we have the next weekend so we can try and do better."
Scuderia boss Mattia Binotto said the Italian outfit would dig deep into the data to try and understand the issues impacting Vettel's car.
"If you look at our race today, at least on Sebastian's side, it was a difficult race. On his car, we can do a lot more," Binotto told Channel 4.
"He lost some track time on Friday, which was not helping. But he was never confident with the car this weekend, so there is a lot of data to look at, to try to understand and to address it.
"So while eventually on Charles we will look at the data, and try to optimise and let's see what we can do, there is much to do on Sebastian."
