Button: You jump in the car and everything feels good

By their own admission McLaren- Honda endured a disappointing day, on day three of Formula 1 testing in Barcelona where once again technical gremlins hampered their programme with Jenson Button on duty.

The team reported that their day "was cut short by a failure of the revised seal introduced [Saturday] in a bid to resolve the week’s MGU-K issues."

And added, "To compound a tricky day, Jenson suffered a punctured intermediate tyre during a practice pitstop, coming to a halt before the end of the pitlane."

After a good day with Fernando Alono in the cockpit on Friday, Button was less fortunate, "[Friday] wasn’t bad, with more mileage and lots of data gathered, but [Saturday] has been tricky – it hasn’t been my day."

"We had a similar problem to the one we faced on Thursday, with the faulty MGU-K seal, so the afternoon running was limited to aero testing and pitstop practice."

"I still can’t comment on where the car will be when everything is running smoothly, as I haven’t had the chance to run it properly without meeting problems."

"Having said that, I feel like there’s definitely nothing wrong with the car or any stand-out issues with drive-ability. You jump in the car and everything feels good," added the 2009 world champion.

"Hopefully, our problems will be solved sooner rather than later, but tomorrow is still likely to be a reasonably difficult day. There’s a lot for us to improve at the moment – we’ve still got five days of testing left, so hopefully they’ll be five good days," added Button who scored McLaren's last victory at the 2012 Brazilian Grand Prix.
