Whilst his team has made huge strides since it's last outing at the Circuit de Catalunya, Sebastian Vettel remains philosophical.
"We have to wait and see what's happening on Sunday," he said ahead of this weekend's Spanish race, "as Barcelona has always been historically the track where to bring updates, sometimes bigger, sometimes smaller.
"We're doing as all the other teams, bringing updates to catch up who's in front of us," he continued. "Every time you bring new parts you have to wait and see if they're working well or not when you're on the track and it also depends on how big is the step that the other teams has done.
"Compared to the gap to the other teams we've seen here during the winter test session three months ago, we've improved a lot, but the gap is still there," he admitted.
"What we really need is to be faster, in every condition: it's true that we know this track very well, but it is also true that we have very different conditions compared to the winter session. It is 15 - 20 degrees hotter now and I don't need to explain you what does it mean.
