From a couple week old look at the parts list, I can also share here that:
-the coil P85D has differenct springs in back, than the coil 85D.
P85D SAS:
-26/21mm pre-April SAS sway bars, front and back
-24/20mm post-April SAS sway bars, front and back
-24/20mm coil bars, all coil P85D
-The above sway bar diameters confirmed caliper measurements folks have provided.
-P85+ uses entirely different front/back air units, than any P85D.
The above means people describing "The +" suspension are actually descrbing two different suspensions (P85+ vs. early P85D). P85+ sway diameters are curiously not listed next to their part description.
There were no entries, yet, for P90D or 90D.
[EDITORIALIZING] Saying cars with equal front/back weight "handle better" doesn't make them fun to drive. There is such a thing as fast, safe and relatively boring. It's also harder to point a car with equal front/back power. Other makers of performance AWD don't equip the front and back with nearly equal power (the Porsche 918 has "Volt" power, up front). Actually, I'm not sure we know if 85D has equal power either. Motor size doesn't have to correlate to output. Tesla could go ubber safe, and lean toward FWD. Whatever, I think they mostly focuses on range.
