But the story is similar for every team today, except Williams. We can all go to sleep tonight dreaming that they have a Brawn 09' up their sleeve, but the reality is very different.
We saw their new driver, Formula 2 champion George Russell, in the paddock today, and their 2018 car is in the garage in Spain dressed up in the new livery, but the rest of the team are back in Oxfordshire, working hard to get the new car ready in time - hopefully by Wednesday according to Claire Williams, the deputy team principal.
George Russell, spoke earlier to Sky Sports, he said: "I want to be out on track and the team is working hard to get everything sorted, I don't think it will compromise us too much."
But we shall see what happens over the next few days.
We will be back tomorrow from 08:00 GMT, with more coverage of F1 testing in Barcelona.
