Adrian Sutil has said that he is looking forward to beginning his Sauber career in earnest when he drives at the season-opening Australian Grand Prix in March.
The German racer moved to the Swiss constructor after leaving Force India, who recruited Nico Hulkenberg and Sergio Perez for their two seats in 2014.
He told Sky Sports News: "The car is quite good actually, but what can we say? We have no reference really."
In November, Sutil made an unusual comparison between the performance of his Force India car and a carrot.
