Model S insanely fast. Instant torque whenever you hit the accelerator no matter what rpm. The torque is so strong it feels like a turbo that's always on boost. Its the first factory car I drove that I think would beat my turbo 3.2. Its really hard to tell from driving because they are both so different, but I can say that from a dead stop the Porsche wouldn't stand a chance. My sweet spot is 3rd gear around 3400 rpm turbo spooled up, but the Tesla seemed to pull just as hard. No running rich or lean, or running awesome one day and like crap the next, no clunky gears to shift. (just a singe gear thats it) just smooth, quiet, brutal acceleration 100% of the time. I'm really curious to see which would win from a third gear freeway run. I dont see how an internal combustion engine can compete with this and I see no advantage. For the first time my highly modded Turbo felt extremely antiquated. The Porsche still looks cool though.
