About the apples to oranges.... or unhatched chicken are being counted coments...
I seriously doubt Peugeot did any compromise for their car, they did the car they thought was the best for PP. Heck they even put into the car the best driver available, someone who is considered by some the best four wheel driver ever, so they obviously did the best they were able to do
Same for VW, except they put into the car a WEC driver who, IMHO, is light years from Loeb category, specially for PP as that´s very very, extremelly different to WEC. Even so he demolished Loeb time. To me this is self explanatory
