Nico Hulkenberg admits he does not expect to be given any kind of grace period by Williams as he prepares for his first season in F1, with positive results expected immediately.
The German, who enjoyed his first test in the FW32 last week in Valencia, insists that the Grove-based outfit expected to be on the pace from the first race in Bahrain and that he too will have to be up to speed from the outset.
"That is the target, for sure," explained Hulkenberg.
"There is nobody who says that you have five races to get up to speed, and to deliver. It is straightaway you have to be good.
"Williams expect me to deliver a good job, to drive quickly and do well for them. They would not appoint me as a driver if they didn't expect something from me. They have not said what that is in terms of numbers or results, but expectations are always there."
Having achieved title success in last season's GP2 series, the 22-year-old feels he is well prepared for the rigours of Formula One.
"I feel a lot more self confident and ready for F1," said Hulkenberg.
"Doing a year in GP2 helped me quite significantly and made me better in all aspects. I enjoyed that year and I definitely feel ready now for this big task.
"I had a great year in 2009 and I didn't expect at all to be that competitive in GP2. I expected a very difficult year, but it turned out okay - and the second half of the season was mega.
"If I can adapt as quickly as I did in GP2, then it will be very good. The testing amount is not huge before the first race, but I will do my best to get there as quickly as possible," he added.
