Sebastian Vettel is adamant that Red Bull's Formula One car does not match his driving style as he endures a frustrating season.
Due to the extensive regulation changes before the start of the campaign, F1 cars underwent a transformation and Vettel has not been happy with his individual adaptation.
The German has been crowned world champions four years in a row, but his dominance has come to an end as Mercedes duo Lewis Hamilton and Nico Rosberg fight it out for the title.
Vettel enjoyed his best race of the season in the Singapore Grand Prix, finishing second behind Hamilton, but he knows Red Bull have plenty of work to do in order to compete with their rivals.
"Every time I want to push or make something happen, it just doesn't," he said.
"I think it is a characteristic of this year's car in combination with the downforce we have, with the tyres.
"It just maybe doesn't give me yet what I want in a certain area of the corner.
"That is not an excuse, because in the end I have to get the best out of the car. We've done a lot of progress but there is a lot we can do better.
"Obviously you drive the way you think is quickest, whether that means you have to hold back or you have to push, it depends on the situation.
"It is not that straightforward this year and it is not always consistent, so that is the tricky bit.
"I think we got in a lot better shape in the last couple of races but there are still some things where we are a little bit too much on the edge."
