The Nevera gets to 60 in 1.74 seconds with about 800 more HP and 300lbs of additional curb weight. Using some fuzzy Biden math, if all engineers were equal, the Model S could technically do a 1.85 0-60 without the 1ft rollout with an extra 400hp.
I know for a fact that there's nowhere near 1000hp being put out during a Plaid launch. It can't put the power down no matter what surface you're on, so they can probably improve 0-60 today without adding more power - so yes, I agree that more power would be useless given its current design but the schlong contest on the street is what matters here
