After the first day of practice running for the Italian Grand Prix, in which Ferrari ran an upgraded power unit, Sebastian Vettel said the Ferrari's performance was "OK" but also that there is more to come.
"We are not going round to have a cup of coffee" said the German after finishing the second Friday practice session in third place behind the two Mercedes, just under half a second off the pace. "Obviously we're trying a lot of things on Friday, different things, full beans, not full beans. On Friday it's always difficult.
"It felt OK nevertheless, but the feeling's not yet right, we need to look at the car and find some performance.
"I think we can do more, I think we can improve from where we are."
Vettel suggested too that the improvement in the rest of the weekend would be found in the car as well as the new power unit. "The car feels good, we just need to make it feel good in every corner and bring it together. But other than that the first impressions are positive."
"It's [the engine is] doing what it's supposed to do so that's positive – obviously on Friday you try a lot of different things. You need to wait a little bit more, tomorrow, Sunday [to find out how competitive the engine is].
"It's Friday after all so it's not the most important part of the weekend, but it's important that we ran and I think we got a decent speed."
Vettel however was cautious on the prospect of getting on terms with Mercedes this weekend. "We can see the Mercedes is very good, very strong, similar to last year. They seem to be very competitive around here.
"[But] we focus on ourselves."
