Same as last month - 250 wh/mile. Longer trips were better (down to 225 wh/mile) but as there were sometimes days between uses, and many short trips, the potential efficiency was better than reality.
24.26 kwh used this month. |

250 wh/mile this month. Motor brushes advanced 5 degrees from stock. Slightly better acceleration and efficiency. Many drives this month were three or four miles which makes wh/mile go up. |

240 wh/mile average for April. Warmer weather and longer average drives (at slower speed - not maxed out...) make for better efficiency! |

126.5 US |
26.91 kWh used in January for 93 miles. 289 wh/mile. Dragging brakes after brake replacement caused higher than normal consumption this month.
Brakes readjusted for zero drag near the end of the month, improving wh/mile figure from 300+ wh/mile back to a more normal 250 or so. |

37 EV miles in last half of December using 11.13 kWh.
.3041 gallons equivalent.
301 wh/mile. 10 degree Advance in motor timing didn't help speed or acceleration, but caused a drop in efficiency. Motor turned back to 'stock' position after the two week test. |

272 wh/mile. Defroster use and cold are conspiring to lower the efficiency... |

142.86 US |
38.93 kwh for 152 miles in October. (1.06366 gl equivalent) 256 wh/mile average. A bit higher electricity use than past reports due to a number of short trips. All in all, still cheap - at 6.5 cents a kwh, the 152 miles cost a grand total of $2.53 - a cost equivalent of about 180 MPG. |
