How does eAWD work on the T8 AWD
 

Hello,

Just joined the forum here, hopefully someone can answer a question I've had about the T8 eAWD on the 2019 S60.

I'm in the market for a new car and one of the contenders on my list is the 2019 S60 R-Design T8 eAWD. I've been trying to understand what to make of the hybrid powertrain and I understand that this is an FWD vehicle when the motors are not engaged. Therefore, the AWD in this vehicle is not mechanically implemented but rather comes about when the electric motors on the rear axles are actuated. If my understanding is correct, my question really is, what becomes of the AWD when the batteries run out of juice? Does the vehicle reduce to a FWD or does regenerative braking provide enough juice for the motors to keep the AWD system running?

I'm quite attracted to the prospect of being able to drive around ~20 miles on electric power only, but a little confused as to how things unfold when the battery runs out of juice especially regarding the AWD system.

BTW, I'm also considering the 2019 S60 R-Design T6 AWD, I test drove this yesterday and both my wife and me loved the dynamics, handling and power delivery to the wheels. The re-designed interior was not harsh to the eye either :)

Thanks in advance for your answers/insights/comments.

Cheers from WA state!
