FYI, some hybrids (like Toyota Highlander) have electric RWD separate from the FWD driveline.
If you have driven the S on ice/snow/mud you realise how little power it takes to keep the car going as opposed to bogging down. Decreasing the TC effect just a bit (a SLIPPERY position) would be helpful. The AWD needed here is more like the 'front wheel assist' that is popular in the tractor realm. Just enough torque to keep the front wheels turning slightly faster than ground speed. This could conceivably be delivered by rim-drive units although these would increase unsprung weight. Or very small inboard motors that disconnect completely (freewheel) above 20 mph. A retro-fit kit would be awesome.

I'm willing to bet based on this: Careers | Tesla Motors
that there is no AWD Model S mule rolling around yet.
Cut and paste from job posting:
· Required to build ‘mule’ model S 4WD vehicles by modifying model S 2WD vehicles.
· Cut and shut current structure to incorporate a front powertrain
- Fabrication and welding experience with some structural capability (good engineering judgment) is also ideal.

No reason to hide it. Tesla has said that Model X will be based on the S platform and the X will have AWD option. Sooner later they need to play with an S platform based AWD. It then makes sense to look at a Model S AWD option but that doesn't mean it will come before the X or even at all; won't they have to re-do safety and crash testing for an AWD Model S?

I think it would be a good thing for Tesla to announce a Model S AWD based on the Model X drivetrain and start to accept reservations as soon as possible for it.
I think that would be a mistake. Initially they should avoid diverting 4WD away from Model X until they have it right. (Once they have it right they'll have performance 4WD which means that they can do everything.)

Agree. But I thought that the AWD drivetrain for Model X is ready and that Tesla is only developing the Model X as a whole.

To this concern I would like to add that IMO many persons, also among TMC Members from what I read, could be interestested to an AWD Model S. So why not to produce the Model X and the AWD Model S together in order to allow a better choice to somebody interested to the Tesla AWD System?
They may think it's ready, but as it's new, software-controlled electric 4WD I'd hope they'd want to make sure it's right in one product before adding it to another. There's plenty of demand for the 2WD Model S, and there's also a very pressing need to get the driver assistance tech completed as well as continue work on reducing vampire draw. In my view a 4WD Model S would be an unnecessary distraction to the business.
