> AWD means that all the wheels receive power from the power train.

I used to think that, until my car (Dodge Charger) with AWD had its tail swing out on ice. Basically, AWD for that vehicle meant "Rear Wheel Drive until it slips," at which point the front wheels would receive power.

Same with my Toyota Prius, though it was FWD until it slipped, then the rear wheels kicked in. Even my AWD EV with dedicated motors doesn't have them all active all the time.

The Subaru is the only AWD vehicle I've owned which was full time 4 wheel drive.



We typically refer to these as RWD-biased AWD, etc.

BMW’s xDrive is a RWD biased AWD.
