I don't have the numbers, but we went from a Ford Expedition EL (2016 model) with the Ecoboost V6 in it to a Tesla Model X.
The Model X cost us more, the monthly payment was higher, and up until 2020 / Covid we had more money at the end of each month than we used too, something about not getting that $400 gas bill every month (used a BP card at nearby BP for most gas)
We charge at home, my electric provider doesn't have any variable rate or anything, it's a flat 0.13 per kWh.
Sadly I lost my miles and info when Automatic died, as I used their little OBD dongle to track my consumption on my Expedition. They died during covid and I was unable to rescue the four years of data so I could show my work, then I accidentally deleted this one write up I did comparing a 2200 mile road trip between the Expedition EL and the MOdel X at the same time of year/same temperature one year apart.
At a high level, we spent $380 in gas and $91 in electricity. The Model X took 4 hours longer as we had to stop and charge ~ 200 miles where the EL had 500 miles per 33 gallon tank (roughly) but we averaged about 12.5 miles per gallon vs 88 MPGe. I hadn't learned how useless MPG was as measuring efficiency (Gal/100 Miles is better) and didn't get those number converted.
We used Tesla Superchargers the entire way there.
So I don't know what fancy math this article used, but my personal experience doesn't match it. I'm sure the truck will be worse MPGe as it isn't as wind streamlined as the model x is but I'm buying it to reduce emissions not save money.
but SUV to SUV, both with AWD the EV did much better for us.
I've always felt that if an article is written to tell you why you shouldn't buy something and then try and use math to do it, having worked in product management for 18 months the gyrations people go through to justify something that only works if you squint and tilt your head and forgot all reason...I call BS on the article.
