I haven't had it long enough to use it in a motorsport environment yet, MaikuL, so I couldn't tell you yet, unfortunately. The camera was only released late September/early October.
However, in saying that, I did have some success with my 450D at WTAC/Superlap, and seeing as the 60D is a better camera with faster focussing, a faster burst mode and better resolution, it should be nice. I'll have to find some photos from that and post them up.
