Robert Kubica is hoping that a year in testing will put him in a good position to gain a full time race seat in 2019.
Kubica explained his optimism, saying: "If I am able to prepare and use the opportunity to get me closer and then if I have the chance to drive or come closer to race I will be for sure more prepared than a couple of months ago.
"Every day you can learn something new and I think at the end of the year, I think I will be better - maybe not (a better) driver - because when I have been in the car I have different priorities.
"It's not about fine tuning and small details, it's more my job to get a global picture and it's more about feedback, trying to find weaker points of the car and give suggestions and ideas to improve the car.
"It's not just about pure speed and pace but still it's a good opportunity to learn new things and be in the car."
The Pole is excited by his new
Williams adventure, and said: "It's a good feeling for me. If you think where I was 12 months ago things have changed quite a lot.
"I am enjoying my position, it's giving me quite a lot of challenges and also opportunities to see the team working, to see a different point of view of many things.
"It's a good opportunity and I'm enjoying it. It's also good fun. I think it will be an interesting year".
