Valid points but if you're looking for that kind of prolonged performance the NSX is probably the wrong car?
I dunno. In a lonely freeway or dragstrip situation, you only need WOT power for 10-15 seconds before the system gets plenty of chance to use regen and/or parasitic charging to fill the battery back up. I am assuming that in Sport+ and Track mode the battery SoC is kept at a level to allow for this amount of WOT time.
My hope is that "consistency" on the track (which is MUCH harder on the car than isolated sprints) is not achieved by throttling max performance too much. Consistency by itself is easy. I'm looking sustained maximum performance.
Only testing will reveal the answers.
