I believe you're correct, that pushing it to the firewall basically cancels out the constrained Eco acceleration mapping and gives'er all she got. Never timed it though.

I feel pretty confident we're right. I just did 8 runs on the country road near my house, battery 60-65% during the test, outdoor temp at 45 but car had been through it's normal morning warmup and I'd driven for 40 min, tires were up to temp, it was happy. Full "throttle" was giving me repeatable results, traction control was "off"/dynamic mode, climate control off. Not very accurate, but I'd start from a stop at painted line and read the speedo (which lags, and is rounding) when the next mailbox crossed my a-pillar, coast on down the road and come back for another run.

58 run1 (I may have lined up a little different on the first run)
61 run2
63 run5
61 run6
Just like Mike Tyson famously said, "everyone has a plan until they get punched in the mouth," I think everyone plans to drive conservatively until they punch the pedal to the CFRP (whether our of necessity, impatience, or raw lack of restraint, who am I to judge?).

Great question and thanks for sharing the informative test results.
If I understand correctly, the ~61 values listed above were the speeds indicated in the speedometer when passing a fixed point/mailbox. However I wonder if that's only measuring speed and distance, but not total time. We're relatively new i3 drivers, and the Eco Pro mode may have a brief delay before kicking into the same power curve.
Would be interesting to see results If a second person (or possibly some app) could measure time to reach the fixed point/mailbox in addition to speed.
The Sport mode in the i3s makes a substantial difference when rolling. There is a considerable difference between modes once the car is on the go. Not from the start. I can easily jump ahead just from the fact that Sport mode responds so quickly.

Yes those are speeds in MPH. And while measuring time would be helpful, I *think* I can assume that if there was a delay, or the car was slower 0-10, then it wouldn't have caught up in the same distance, and would be going slower by the end. I'd be happy to repeat it with people and stopwatches, come on down!
