They have different AWD systems in different vehicles and for some vehicles there is more than one system depending on which transmission you purchased. (At least when there was a choice) Mine is electrically controlled (and many Subarus are) but it's still connected full time. IME driving other electrically controlled non-full time systems what you feel in those are the electrically controlled clutch packs completely disconnect the rear wheels and the AWD is 100% disabled until the traction control system kicks in. Then you get a brief moment where the car feels out of control until the clutch activates the AWD. The tradeoff is that system that completely disconnects the rear wheels results in those vehicles (E.x. Honda/Toyota) getting much better fuel economy than Subarus as they operate as front-wheel drive almost all the time. I have never been in any Subaru that behaved that way. And a roller test is not where it matters anyway. Roller tests are contrived. Where you feel the difference between permanent AWD and part-time AWD is medium and high speed situations where the vehicle starts to lose control. Most people will never put any family crossover/SUV into a situation anywhere close to the roller tests or hill ascent tests. All of this seems to become completely meaningless with EVs being the future.
