TSLA will win
Drag radials would not help a P85D very much, in my opinion. In fact, the extra rolling resistance of the stickier tire compound may actually hurt the trap speeds. There is no traction issue with the P85D, and the computer doesn't need to activate traction control from what I have seen- so no real reason to go with stickier tire compound unless auto crossing or taking it on a road course, where you would want R compound tires for enhanced cornering ability. That's a whole difference ballgame, as the P85D wont hold a candle to pretty much any 250HP+ ICE vehicle with decent suspension.
It seems I misread that post a little as meaning the P85D AWD can do burnouts (with TC off or so). That's not what it actually said, and I checked other posts in other threads and apparently that is not the case.
However, it seems the statement about risking damage to the drive shaft when using drag radials, on the hellcat, still stands. And since the hellcat isn't that much faster with them, it apparently needs these drag radials to beat the P85D (although this is perhaps not completely clear). So the P85D has a much better way of getting its power on the road, and full acceleration is available in the car as it comes from the factory, easily and smoothly.
So my summary at this point: For drag racers, the hellcat offers various ways of improving performance, which the P85D doesn't (at least none are known at this time). However, the P85D gives quicker and more reliable acceleration to those who do not want to mod their car and/or don't want to risk damage.
