The bottom line is that I correctly stated that FWD/ AWD platform matrices do not easily nor readily convert to RWD / AWD platform matrices as has been suggested. One does not have to be an engineer to discern that, and in this situation the want to defend Audi continues to cloud understanding of simple AWD system descriptions.
Audi Quattro has rarely if ever been considered the best AWD system, and in many ways Porsche as well as Nissan easily shade Audi's Quattro. Furthermore this believed superiority over transverse engine AWD setups in every way has been already proved wrong by Audi's own TT RS, and vehicles like the Mitsubishi Lancer Evolution.
If it makes you sleep better perhaps telling yourself that Audi's Quattro is the best in the world will work in place of an Ambien.
A larger question would be if Audi's MLB platform in it's base format is FWD how could it be anything aside from FWD based AWD in it's nature? If MLB can easily be converted to RWD why is VW/ Audi developing MSB from the Panamera's architecture when it would be easier ( as you both believe) to convert MLB to RWD?
I can not for the life of me understand why those who at first argued with me adamantly because they thought FWD based was a term not divergent from FWD biased will not admit how quite erroneous they are. Are there any RWD variants of the MLB platform?
