Ross Brawn says Mercedes is making progress with the W04 despite not bringing any updates recently.
The team principal is adamant that performance has been found as the engineers have been able to hone a package that has remained consistent in terms of actual parts.
“We are chipping away at trying to find improvements to the car,” said Brawn. “As I’ve mentioned before we can’t do it at the expense of next season. But there’s little things with the set-up we’re trying to do, there’s little things to better understand the tyres.
“Sometimes when you don’t change the car very much in terms of development you consolidate what you have and you explore the set-ups more, because you’ve got fewer things to play with. So we’re exploring the set-ups, the balance, the aerodynamic balance, the mechanical balance. And there are little things coming out which are accumulating into a decent improvement.
“I’ve seen that so many times before, that when you fully explore the package, and you consolidate what you’ve got, it’s surprising how you can move forward. I think the last couple of races are a good example of that. We’re in a different place with the set-up than we have been for a few previous races, and it seems to be giving some benefit. Not enough yet, but it seems to be some benefit.”
