the model S performance competes against M5, E63 AMG PP, Audi RS5/6/7 and can't beat any of those in 1/4 mile or 0-60 times. i would disagree with "beyond amazing", it's at the rear of the pack in terms of acceleration and handling.
if you've never actually driven a fast car, i'm sure it's very impressive, but objectively, it's not fast compared to its competition.
it appeals to a different crowd, the kind that wants EVs. i bet most people who considered/bought the S perf have never seriously considered an M5, E63, RS, or even Cadillac V (since we're talking American cars here). all of those handily beat the S in every benchmark.
