"Robert played an important role for us - and certainly we did the same for him," BMW Motorsport director Mario Theissen said, "He joined us in 2006 as a test driver with
no F1 experience, and then we promoted him to be one of our team's drivers during that season. He never let us down and, with our first pole position in 2008 in Bahrain and first victory the same year in Canada, he set milestones in the history of our team. We are grateful for his strong and constant performances and wish him all the best for his future."
Kubica admitted that the landmark moments will remain 'unforgettable moments' as he moves on.
"I'm very thankful to those responsible in the BMW Sauber F1 team for giving me the chance to get a F1 cockpit," he noted, "I think I justified the belief in me by delivering good results. For 2010, I will have a new challenge, [but] I wish everybody I worked with at the BMW Sauber F1 team all the best for the future. I'm sure that, in the future,
our paths will cross in F1."
Interestingly, the announcement from Enstone made no reference to the length of Kubica's deal, suggesting that it may, initially at least, be for just one season, and neither was there confirmation of his team-mate. Amid rumours that Romain Grosjean may not be retained after a lacklustre start to his F1 career as replacement for the disappointing - and later disgraced - Piquet Jr, there is speculation that another former Renault driver, Heikki Kovalainen, would be Kubica's preferred option, while Timo Glock and Adrian Sutil have both also been mentioned.
