- Jerez Test, Day One
'Times mean nothing right now' - Button
Button was nearly a second clear of his nearest rival, Mark Webber's Red Bull, with Webber admitting it was a "pretty handy time". But Button, who only completed 37 laps due to a fuel pump problem, said the time means little at this very early stage of pre-season testing.
"To be fair, I was surprised when I saw it on the dash, but it doesn't mean anything," he said. "I think some people run less fuel than others and some people run a lot more fuel than others, so who knows?"
He added: "I've already had the question 'is it a championship winning car?' but who knows? The important thing is there's a nice feeling in the car and lap times mean nothing right now. They don't even mean anything at the last test, it's when you get to the first race that we'll have a very different car, as every team will, and that's when we need to really show how quick we are. Today's testing and everyone is doing different things. The important thing is that the car really does relate to the simulator and that's something that's good."
Button's fuel pump issue came after just three laps, with the team saying it was similar to the problem that brought Lewis Hamilton to a halt in Abu Dhabi despite it being a newly-designed part. Nevertheless, Button tried to put a positive spin on the issue.
"On the first day of testing there is so much excitement within the team and in the paddock, but for us it was very short lived, just doing three laps this morning and having the fuel pump issue," he said. "It's never what you want at the start of a test but it's better to have it at the start than at the end of the test, so we can solve the issue. In terms of the feel of the car it's a nice starting point, but not the mileage we hoped for on the first day of testing."
