Can't help with the sharpness test I'm afraid.
But I'm also looking at a 70-200 for motorsport shots,so I'm thinking it needs to be the 2.8 version.

I was comparing both versions (f/2.8 and f/4) in these very sample threads here,and after looking at both I'm in the same frame of mind as you.

Don't get me wrong,the photos in the 2.8 thread were absolutely fantastic but the difference in sharpness of the 2 lenses seems quite significant

Take a few shots with your camera and lens on a tripod, shoot something static, set the lowest iso, for example iso 100, I think set the aperture to somewhere between f4 and f8 (someone correct me if this is wrong), use the self timer or a cable release to trigger the shutter to minimise movement of the camera, turn off image stabilisation (when on a tripod), and then bump up the sharpness in dpp or photoshop.
