That VW has a gurney flap on the diffuser, is that for diffuser function or air flowing over the top of the diffuser? Has anyone seen any evidence for this or heard of it before?

The location of mass does not matter for a just a crosswind, only the total. This shape looks as if it might have less drag in a crosswind, working as a sail. For real benefits, though, the sail has to be able to spill wind if overturning is imminent for any reason. With a bit more activity, it should be able to resist cornering forces directly instead of through downforce.
