I think they may surprise a few this year and move up the grid a little. According to this http://scarbsf1.wordpress.com/2011/01/31/sauber-c30-launch-detail-and-analysis/ they have a few innovative ideas that others haven't thought of (at least not yet) and they apparently also have a front exhaust system similar to the Renault's version in development... Thoughts?
Actually, in terms of pace last year (not results) they were ahead of FI in second half of the season, but usually behind williams. Williams were faster than force india in second half of the season.
I think i read recently that they have tied up some South American megabucks as has Williams, so it could be that they improve throughout the season, and will have a proper car in contention next year. The more teams in contention the better I think.
