What's wierd is that 3 months in and I'm still continuing to evolve my driving habits on the Energi:
September - Followed the normal technique advertised in this forum where I stay under 2 bars acceleration in auto mode for most driving, and then go to ev-later when getting on the freeway. This generated decent MPGe numbers, but horrible EV driving range (18-23 Miles).
October - Kept car in EV-now mode most of the time, except when getting on freeway. Learned to coast the car whenever possible and have hybrid assist enabled whenever possible. Average MPGe increased to around 84, but EV range kept in the 20-25 mile band.
November - Since I live in a high electricity cost region, I noticed that according to various online MPGe calculators that driving 250 miles at 42MPG gas was only a buck or two more expensive than driving the same distance with 120MPGe electric. Electric can regularly reach around 25 cents/KWH here. Also, I found myself wanting to reduce the frequency at which I recharged the electric battery. So, I switched my driving pattern so that while I continue to coast and have hybrid assist whenever I can, I'm switching to EV later immediately whenever I'm in any area with hills or where I might go >50MPH - reserving EV now mode only for when I'll be driving in flat or downhill areas between 25-45MPH. Average MPG has gone down into the low 70's, but EV range is oscillating between 28-40 Miles.
What I haven't tried:
- ECO Cruise Mode, I'll experiment with this during my next road trip.
- Switching frequently between EV auto and EV later while driving on the freeway (seems like too much of a hassle).
