On the plus side . . . she has a very short commute, so not much fuel's needed :o). Her actual annual mileage is around 13000m, so less than half of this is the short commute, the rest other driving needs.
Gary, what the heck is the "L" regen? the "N" double tap? I think the double tap is to the brakes to help force EV operation right, but the 'L" is a mystery!

The key to getting and maintaining EV the longest for me is the use of "L" regen and the "N" double tap (or more) till the ICE shut down.
First of all, there is no "L" (LOW gear) as the shifter would lead you to believe. In other words, you can drive just as fast in "L" as you can "D" (DRIVE) with the eCVT. There are four ways to get regenerative braking before the brake pads are used to slow the FEH/MMH. All regen (regenerative braking) is, is the Traction motor/generator taking energy from the wheels as you let off the gas or apply the brake pedal which is both if you drive with the right (one foot) foot like you are supposed to. The computers changes the traction motor to a generator to recharge the HV battery. Both electric motors can be turn into a generator, one by the engine and the other by the wheels. Since the traction motor is larger, it can generate much more energy faster for storage in the HV battery. If you take advantage of this system like I do every minute I drive my FEH, you can increase you mileage by driving more EV and reducing the load on the engine when charging the battery with the small generator. The four ways to regen are:
1) Letting off the gas pedal in "D" (the "D" Fake Shiftt) is the least amount of regen going to the battery.
2) Letting off the gas in "D" and applying the bake pedal, will give you more regen.
3) Letting off the gas in "L" (the "L" Fake Shift) is the one I use the most for killer regen.
4) Letting off the gas in "L" and applying the brake pedal will give you the max regen. and charge to the HV battery. Only use this for stopping
Neutral brake tapping is sometimes required because the HV battery is to hot or cold or the traction motor is to hot preventing charging by the control computers. In neutral ("N"), all regen is not possible because of a disconnect of the wheels to the traction motor. I discoverred that if you shift to active neutral and tap the bakes, the engine will shut down most of the time when it will not in "D" or "L". This is very important, to me anyway, because I can go EV under 40mph any time I want even if I have a cold or hot battery or hot traction motor. Using this knowledge along with "N" coasting in the 25-35mph speed range, I have hit 70.3mpg on a 20 mile round trip in my FEH.
