With MIMA if you force enough Assist and high enough ICE RPMs to get into fuel cut mode you are in a pure EV Mode ... will work in any gear or speed ... as long as you have enough Assist induced load and high enough RPMs to get to fuel cut ... I've done this a few times years ago as an experiment in all 5 gears.
Same as Option #1 , except using FAS to force a fuel cut at lower RPMs and or Assist levels... I did this a a few years ago during the same experimenting , and was able to go 3.7km from a dead stop up a slight incline.
If you are already getting some assist when you run out of gas ... you can keep going on IMA Assist until you also run out of IMA battery... I did this during the same experiments where I used FAS to simulate running out of gas , and just flooring the gas pedal in higher gear to get the IMA assist , without using MIMA ... but the MIMA options in #1 and #2 above do given more control over the amount of Assist being used.
I do not know if this behavior is the same on all versions ... but it worked consistently with my 2000 I1 a few years ago when I did the experimenting with it.
I could be wrong ... but I thought the I2 made use of the closed pistons ... turning the pistons into air springs ... and thus had a more efficient EV mode ability due to not running the ICE as a air pump.
