You are missing it.
Bigger battery weights more, a LOT more.
Weight kills performance and handling!
The battery weighs more, which hurts acceleration. But it also can deliver more amps, which more than compensates. Bottom line, the car with the bigger battery can go faster, providing the motor and PEM are suitably designed.
Weight is a handicap not just during acceleration, but even more so during braking and cornering.
Battery chemistry may, or may not, support increased acceleration from bigger battery (please site your sources to confirm this). Bigger and heavier battery will absolutely inevitably result in longer stopping distances, slower slalom speeds, slower response during emergency maneuvers, and slower speeds through turns.
A quick Google search turns up nothing quicker than 2.2 seconds to sixty. The 2020 Roadster supposedly will do it in 1.9 seconds.
Not anymore.
Tesla has given up on sub-2-second 2020 Roadster acceleration claims for 0-60. Causes not publicly shared.
I remember reading new 2.1-2.3 second time 0-60 estimates. I guess, we will find out once it is finally released, as the car is still in development.
For 1/4 mile, 0-100, or Nurburgring times, Tesla's have done OK, but never at the top of the pack:
Car 0-100 mph times list - List of Fastest Production Cars 0-100mph Ever in Order, Figures, Specs, Information, Top Speed and More
List of Nürburgring Nordschleife lap times - Wikipedia
Tesla never delivers anything on time. But when they do deliver, they meet the promised specs.
Agreed on the first point.
w.r.t the second, there was some slippage with 2020 Roadster performance expectations. Again, not sure why. Wish someone who knew would share...
As for track handling, I have no thoughts or opinions. I've never been on a track and I've never visited a track. I once tried to find an instructor who would teach me high-performance driving techniques in my Roadster, but couldn't find anyone. The local ones listed on line never returned my calls or emails.
I took every car I ever owned (other than minivans) to autoX and track to safely learn how it feels near limits of adhesion, and how the car communicates to you that it is approaching those limits. I would never feel safe driving a performance car otherwise.
If this resonates with your, consider the following organizations that will be happy to hook you up:

Enjoy your car either way!
