Lewis Hamilton admitted that Mercedes has a lot of work to do after the team struggled badly in afternoon practice in Monaco on Thursday.
The former champion was fastest in the morning session, but the team lost its way in the warmer conditions in the afternoon, as both Hamilton and his team mate Valtteri Bottas struggled for grip. Lewis was only eighth fastest, and was 1.1s off Ferrari’s pace.
“I can’t, because I don’t understand it,” said Hamilton when asked to explain it. “P1 was really good, the car was feeling great. Then there was night and day difference, black and white. P2 was a little bit different, we couldn’t work the tyres for some reason, lots of sliding about.
“Lot of studying to do to find out where we went wrong, but I’m confident in my guys. I don’t know if it’s set-up. It’s just with the tyres, I don’t know why the tyres weren’t working.
“That’s something we have to study and figure out for Saturday. It gives the guys here more time to work on the car, spread over two days, rather than everything tonight.”
Asked about the challenge of driving round Monaco at the record speeds seen today he said the higher downforce levels made it easier.
“It’s the same as before. The car is a lot better, it’s got more grip. If anything, it might be easier. It feels great. Monaco is always amazing to drive, and it’s definitely the best car I’ve driven round here.”
