Wow 16l/100km adds up pretty quick.Yes, I'd use off peak rates (Markham that's a little over 11cents/kwh. (7.4c is our energy charge- but to compare apples to apples you have to include the variable charges too - delivery 1.33c, transmission .1c , line loss adjustment .325c, , debt retirement .7c and HST 1.28c bring my off peak to 11.2c/kwh.)
Comparing Volt to a Cruze is what I did to when I bought my first Cruze in 2015. At that time, comparably equipped cars were OTD 40k (with rebate) for Volt, 21k for Cruze. Gas was 1.10/l.
I wanted the Volt, wife was skeptical. She agreed to go forward if I could show her how a Volt would save us money. I couldn't make it even close.
I still wanted to try electric, tried again in '19, Cruze vs Bolt, Iconic, and Leaf. TCO closer, but still a huge premium to drive an EV.
Its gonna be different on my next truck. 16l/100 vs 40kwh/100km will make a truck much easier to justify.
It is a cost premium for sure to drive an electric, but the gap is narrowing each year. I'd like to get a full electric for my next car and when that times comes, there will be even more options. My wife would prefer me to spend more money and get something fun, than spend less money and be totally sensible.
