I would expect, like the Long Range S (which has already done a few 10.9's at 129-ish mph iirc), the X to be slower than an old Performance from a stop, but just as quick from a roll. Model S is trapping at the same approximately trap speed as the old Performance in the 1/4, just with a lot softer first 330'
Which means, somewhere around mid-high 11's at 118-22? That's Urus territory if it's hot enough for it to pull timing and boost (runs an 11.2 in good conditions from a dig), for the "slow" one. I think it'll be significantly quicker than 3/YP from a 60+ roll too.
I personally don't see the point of the plaid X except for the fact that it seems like a decent deal at $15k for 300hp, for now
Or, to put it in EV perspective, the Rivian runs an ~11.7 at 110. That's all launch as the aero/power de-rate at high speed is pretty horrendous on the R1T compared to even an old X. I would think the X Long Range/Base model to do around that ET with about 6-7 mph better trap, in the 1/4.
