Your numbers are off here. Audi's AWD system (as with most center diff AWD systems) is usually factored between 22-25% drivetrain loss. RWD BMWs (and most other RWD vehicles) are usually factored at 15-18%. I prefer RWD for spirited driving, but that 2-10% increase in loss may be worth it depending on your priorities for the car.
