Anyone out there know why Audi does not make rear wheel drive cars? I am well aware of the trade off between space and packaging vs RWD. However it has occured to me that the only real changes to an A3 Quattro in terms of packaging involve reduced boot space - or is the floor plan changed to accomodate the shaft running to the rear wheels? If the former, then would it be so difficult to have rear wheel drive? In simplictic packaging terms, wouldn't this just be the same as a Quattro without the front wheels being driven? Or would the extra torque going to the rear wheels require more substantial mechanicals beneath the floor ie reduced space / packaging? OR is it some kind of marketing thing - would going RWD be seen as losing face to BMW? I am not an engineer so would be interested to hear what the score is. It is said that nice as Quattro is, it isn't all that. Having driven RWD cars for some years, I can say the RWD definitely IS all that.
