Wouldn't that be nice. I just looked up a random example to roughly compare two similar cars.
Their are very good reasons to buy EVs, but from what I can see, at least for most of us, they would be for reasons other than saving money.
Hyundai Kona EV costs about $35,000 NZD more than a Hyundai Kona ICE (Let's say $30,000 to allow for a better ICE version).
On road fuel cost for the ICE version for 14,000km (about average here apparently) is
$2860 NZD.
This equates to 10.5 years worth of petrol alone for the average user, without any account of the cost of electricity on the EV. (Feel free to alter to suit a higher mileage or if you have a heavy foot).
Adding electricity, the cost of financing the $30K difference (which is significant at the moment), less a bit for lower maintenance costs on an EV, and that payback period would escalate considerably.
Please don't misunderstand me, buying EV's is generally very commendable ...... for other reasons.
