The RS4 was more of a halo car for the time being and now they have the R8 for that. I assume that the sales for the RS4 were horribly low and think that it may be a good option for Audi, even if it is a bad option for driving enthusiasts. I think the same can be said for the drops. I am sure the cost of development were not met by the profit in sales. I would say that I don't know about the hybrid thing, but I am sure there are plenty of people out there that will snatch up hybrid A4s for a premium.
