Nick Heidfeld declared himself very happy with his return to grand prix action in practice for the Singapore GP. The German, replacing Pedro de la Rosa at the Sauber team, was quickly up to speed and was able to match the pace of his teammate Kamui Kobayashi.
Heidfeld finished the day in 13th position, just over a tenth behind Kobayashi. Having not driven in a grand prix since last year, believes there is still more to come.
"Given it was my first day back in the team and also in the 2010 car, I'm very happy," said Heidfeld. "I enjoyed driving a lot. At the beginning it was a bit difficult because the track was wet. I just took it easy and tried to do as many laps as possible.
"For the second session we changed a few things, but it is clear two sessions are not enough to analyze everything. I see many areas where we can improve the setup of the car and areas where I can improve in getting the best out of the car. The track itself with regard to the bumps has improved compared to 2009."
