Red Bull designer Adrian Newey is well known for his tight-fitting cars as he pushes the limit of aerodynamics, however there appears to be a snag when it comes to Daniel Ricciardo making the move for 2014, his hips are too wide for the RB10.
While Ricciardo is smaller than his countryman Mark Webber his body is wider than the Australian and Sebastian Vettel.
"It's not my arse per se," the 24-year-old told the Telegraph.
"Even when I signed for Toro Rosso we had to do a few seat fits and they did some scans to make that particular part of the cockpit a bit wider, so that we're not sitting on the actual carbon fibre.
"I can't do much about it. Even if I go on a massive diet my hip bones aren't going to change."
The F1 cockpit to a driver is similar to a footballers boots, the seat is moulded to the driver's body shape while the shape of the cockpit can also be altered based on height and width.
Ricciardo admits the issue will not stop him achieve his dream of racing for the main Red Bull team.
"No chance," he grinned. "I'd shave my hips if necessary. I might die of blood loss but it would be worth it!"
The young man from Perth is also dropping the largest hint yet that he is indeed the man replacing Webber at Red Bull for 2014.
"Oh ok, I'll just come out and say it," he said. "I moved to Monaco last week. There," said Ricciardo, who has lived in the UK for the last five years.
Most are reading into that by suggesting Ricciardo's income is about to soar as a result he is moving to the tax haven in the Cote D'Azur.
However Ricciardo is still not giving 100% confirmation of the move.
"Until something is done I'm not getting too excited," he said. "Then if it doesn't happen I won't kill myself."
