ABU DHABI, UAE - Nico Hulkenberg has promised to do his best to help Force India beat Sauber to the F1 Constructors' championship, even if it costs his future employer millions.Sauber announced ahead of the 2012 Abu Dhabi Formula 1 GP that Hulkenberg would join the team in 2013.Force India is seventh overall, 23 points behind sixth-placed Sauber with three races remaining.'NO QUALMS'When asked how he would feel if he delivered enough points to move Force India ahead of its rivals, Hulkenberg said: "No qualms about that. I'm committed to Force India, we have three races to go. I look forward to the new challenge, the new contract, but also I look forward to doing the last few races here. "I am fully motivated and will give everything."The championship results dictate how great a share of TV revenues each team receives and a single point can have a huge effect on bank balances. Force India's deputy team principal Bob Fernley said the difference between sixth and seventh was around R43-million."I have 110% confidence in Nico, in his integrity and his desire to support the team to the end of his contract," he added. "It didn't even cross my mind that there would be any of that going on. I just think the guy is so straight."Sauber's team principal Monisha Kaltenborn expected no favours from her future employee either. "It's unfair to think Nico would also think that way. He's very professional, committed to any team for which he is working and is at the moment a Force India driver - that's what we have to accept."Hulkenberg said the decision to move to Sauber, which is losing Sergio Perez to McLaren, had not been an easy one to make and refused to discuss details of the contract. He also denied there was any formal link with Ferrari, Saubers engine supplies.Hulkenberg was mentioned earlier in the 2012 season as a Ferrari replacement for under-performing Felipe Massa. His move to Sauber is been seen by some as a prelude to getting a red car in 2014.Massa has signed a one-year extension to the end of 2013.
