How far do the Teslas fall in terms of seconds when you accelerate over and over again? Otherwise very cool that Porsche has achieved this!

This article [0] talks about the acceleration performance of the latest Model S P100D variant at different states of battery charge. Bottom line is that unless the battery is under 10% it is faster than the Taycan. All the stories about the S "overheating" seem to be talking about the older model or this article [1] about how a heavily modified S over heated at a race track. Porsche has to emphasize reputability because it's all they got. I mean they designed an electric sports car that is getting beat by Tesla's family sedan. There is also the issue of how long the car can maintain it's top speed w/o overheating but I'm not sure Porsche is making any claims about that here and that's an issue with any car gas or electric.

I don't think it's cool. Look at it this way. A full battery with the highest possible voltage can deliver its highest possible amperage. Once the state of charge has dropped just a bit, and therefore pack voltage drops just a bit, the theoretical amperage that pack can deliver drops. A P100D does it's crazy 2.4s run on a 100% SoC battery. Let the battery cool and try it again, and you'll get your 2.5s run. Let the battery cool and try it again, and you'll get your 2.6s run. Etc. etc. IN OTHER WORDS... the Tesla motors and traction control are able to take advantage of everything the battery pack can possibly deliver. So as the pack voltage degrades, so does performance. Since the Taycan can deliver max performance runs on a 90% SoC battery the same it can on a 100% SoC battery... that means that the motors and traction control can not take full advantage of everything the battery pack can deliver. OR, it means Porsche literally is limiting the acceleration performance of the car in software. Either way, Tesla wins.
