Drivers Kamui Kobayashi and Pedro De la Rosa unveiled Sauber's 2010 Formula One car Sunday, with the team confident of being competitive despite its late takeover of BMW Sauber.
Team principal Peter Sauber said he would have preferred not to have returned to F1 in such a prominent role but was left no choice in November but to buy back the team he started and had then sold to BMW.
The changes to the new C-29 car coupled with the ban on refueling -- cars will carry at least 353 pounds more weight -- make it nearly impossible to know if the team's hopes of fighting for points at every race are realistic until it gets on track.
