Monisha Kaltenborn admits that Tuesday's roll-out of the Sauber C33 will be a special moment for her and the team.

"We'll be having our roll-out in Jerez and that is always a very special moment, because first of all we'll see if everything really fits together and if the car is running well. It also tells us if we have been working in the right direction for the last nine months. All this makes it a very emotional moment."

"Due to the big changes on the chassis side, but particularly on the drive train side, it is impossible to give any indication about our competitiveness," she admitted, as she anticipates the first round of testing. "We can do that at the earliest after the winter tests, particularly when we have seen where we stand compared to our competitors. As always, it's going to be our target to improve our position in the championship."

"This year we have a very exciting driver line-up," she continues. "On the one hand we have Adrian, a very experienced racing driver, and I'm happy that we finally had the opportunity to work together. On the other hand we have Esteban, a young talented driver who we have known for many years, and has also been a member of the team.

"This is very valuable considering the big changes that are coming this season. I hope the drivers can get to know the car very quickly and that we have all our reliability issues sorted out, so that together with the drivers we can work on the performance and develop the car further."
