We don't really know, but as DGthe3 is pointing out drag is a result of aerodynamic downforce. It increases exponentially, so it is probably a bigger factor than the actual downforce. I simply used downforce because Newmoon drag races and understands the effects of adding weight.

I didn't think my comment would generate this much discussion. The point I am trying to make is don't assume the Z06/Z07 with M7 and Z06 with A8 are going to accelerate the same. Tadge isn't spilling all the beans, but he's been hint a while that the A8 is significantly quicker than the M7 and the aerodynamic forces acting on the stage-3 components up there with some of the best cars around. These two setups may be more different than many people assume.
