There is...The drivetrains for 4X4 vehicles are full-time 4X4 and part-time 4X4. Full-time 4X4 is also known as constant 4WD, all wheel drive (AWD), or full-time 4WD, and part-time one is also known as selectable 4WD.
The Subaru is a AWD system.
The difference between part-time 4X4 and full-time 4X4 is that part-timers drive just the rear wheels onroad, and the AWDs drive all four wheels, all the time.
not true, AWD usually drives as a 2WD and engages AWD only when there is a loss of traction, no driver intervention is needed.
btw op I drive a 2018 XV(Petrol) and is a very good vehicle, only two things I'd have liked more is a bit more power and boot space.
