Button laments incorrect gear ratios
8 September 2013 – Jenson Button was left to rue his gear ratio choice after the Italian Grand Prix, the McLaren driver claiming they were too short to counterbalance the fuel effect.
Despite a scruffy opening lap, Button had featured comfortably inside the top ten for the majority of Sunday afternoon's race at Monza, embarking upon a battle with Toro Rosso driver Daniel Ricciardo for seventh position after the pit-stop phase.
But a lack of straight line speed as his car lost weight left him exposed to his rivals, with Kimi Räikkönen less than half a second away from stealing the final point.
"We didn’t get the gear ratios quite right today," said Button. "Consequently, as our fuel loads decreased, we were hampered by our rev-limiters, and that made it easier for the cars behind to overtake us and harder for us to overtake the cars ahead of us.
"In clear air, our pace was pretty good – but, with such a short top gear, especially with DRS deployed, we were hitting the rev-limiter while other cars weren’t rev-limited."
Button went on to explain that a flat-spot picked up in the closing stages of the race caused further problems, with the subsequent vibrations affecting his vision.
"About 15 laps from the end, I locked up into the first corner and severely flat-spotted my front-right tyre," Button explained. "I couldn’t really see a lot after that, because of vibration, but I still managed to bring it home and score a point for the team."
Team-mate Sergio Pérez finished 12th after dropping out of the top ten late on.
