I mean the percentage of fuel consumption increase (L/100 km or Gal/100 mi) of AWD vs FWD versions of the same car. (Preferably the same engine/transmission if possible, but that's not the case for GSW).

Can also be calculated by FWD MPG / AWD MPG - 1.

For most gasoline cars, AWD fuel consumption should be around 7-8% higher than their FWD counterparts. For the GSW the AWD/FWD difference seems to be exceptionally large.
