Well last weekend marked the first 6 months of Leaf ownership for us. I must say none of the excitement has worn off, and plenty of people over that time (people in our street, work colleagues, random people in carparks) have checked out the Leaf and we've even done the occasional sales pitch. There is no doubt that pure EVs are still a novelty. While people are generally very impressed, even astonished that EVs are commercially available in Australia (very few people have heard of the Leaf or any EV), you can tell they are not about to go and buy one, but you can see the cogwheels turning in their head. We are slowly getting the message out there and seriously challenging people's perceptions.
I've refreshed my three performance charts. The first one is the bubble chart showing energy efficiency vs regeneration percentage, the size of the dots the length of the trip (5km lower limit). The big green dot shows our overall efficiency of 0.142 kwh/km (a bit worse than the early days - we are becoming revheads
) and the regeneration rate is 36.81% (which still amazes me).
We also ticked over 4000 km on the weekend - in line with our historical city running mileage. On only four occasions have we driven 50km or more in a single day, the most 72.7 km. Hence we've never needed public charging.
We have spent $133 on 567 kWh of electricity charging our car (we pay top dollar for peak rate 100% green power, no solar or offpeak). But comparing that to our previous Toyota Corolla hatch, covering the same distance, we would have spent nearly $450 in petrol. Making the Leaf fuel costs only 30% that of a comparable ICE.
The next chart is efficiency and regeneration over time, a rolling average of the previous 100km driven. The data is quite noisy, with no obvious trend, although I have no idea what we were doing the week before Easter to make a mess of our efficiency and regeneration figures. Clearly the performance figures are very sensitive to each trip and how the car is driven.
The last chart is the GOM vs actual distance travelled. This one I have to collect the data manually since the GOM and tripmeter values are not sent to Carwings. No real change from last time, the GOM continues to overestimate our actual driving range by more than 25%. This would have to be one of the very few things that disappoints me about the Leaf. I am sure it would be possible to engineer a much better GOM, but not on this model. I am not collecting any further GOM data, it is what it is, so this is the last time you'll see this chart.
So there you have it! Still relatively early days for us compared to the veterans on this Forum, but we are so glad to have made the leap to LEAF, and can't wait to replace our family sedan ICE with an EV in the next year or two!

. You have a more EV suited daily drive by the looks of it.
