Limited Slip Diff

That's completely different. All of the vehicles have an LSD by that definition. They aren't really the same at all, but they do the same thing. Traditionally mechanical LSD's have performed better than electronic differentials, but in the past few years E-diff calibrations and usages have become much better. Hard to tell the difference in some vehicles.

Personally, I prefer LSD and was the key reason to get S over base. It makes car much better at both putting power down and recovering from a slide. If all you do is drive on the street - you won't notice the difference. If you take it on the track - you got to get LSD. The real one.
I have another car with "simulated" LSD, where ABS-like action on an individual wheel simulates LSD. In the snow (it is my winter car) it works about as well as LSD. However, you can't slide that car around at all. Even with traction turned off, it kicks in and you lose power and gain traction - so it does limit fun a great deal. Now, my winter car isn't F-type, however I suspect JLR has a better system than that in SVR. However, I yet to drive one on the track.

Does the base car not have an e-diff? Perhaps my bad there, for some reason I thought it did. Agreed on the overheating problem, big disadvantage at the track without advanced cooling.

By definition this differential isn't limiting slip. Its a torque transfer device more similar to a PTU than an actual differential. You can program it to do the same thing, but its a reactive device and not a proactive one. I agree they are very similar, but they have a completely different construction and if you loose one of any number of electrical inputs it is, at its core, an open diff.

All V8 F types have an electronic diff.
V6 base = open diff
V6S = mechanical LSD
V8 (all) = electronic LSD

The V6 XE also has an open diff, and there isn't an option for a factory LSD in any trim. Swapping the LSD from an F-type V6S seems like the best option, but no idea if its feasible. The final drive ratios are different between the base F-type and V6S, as well as between the XE and F-type V6S so there would need to be some software modifications. I suspect the XE diff and base F-type diff are identical but haven't confirmed.
I recall reading a thread where Cambo tried to swap the diff in a jag and ran into tons of trouble trying to get change the software in the transmission/ECU to recognize the new final drive ratio. Not sure if he ever solved this problem, but it is really the only hurdle I see to doing a diff swap at this point.

Not a dumb question, I've been wondering this myself for a while.
