256 Wh/km lifetime for a 2013 Tesla Model S 85.
Total spent on fuel in 2023 for 10000 km = $150
We supercharge the car twice weekly while doing errands, 80% of our driving is provided free from Tesla.
First week with a 2023 Ford Lightning Lariat Extended Range, average 400 Wh/km.
With road trips expected to be the majority of the usage of the new truck, this means using the fast charging networks which are slightly cheaper than gas stations.
But we charge at the RV parks we visit, so that's just part of the fee to stay and not a fee I specifically pay to charge the truck.
I expect it to be only 2x cheaper to run than a gas truck, whereas the Model S has been 5x cheaper than the gas car it replaced.
And before you get your panties in a bunch, yes, the Lightning tows well, we've done a one week RV tour of Prince Edward County with a 2022 last summer and it worked so well we bought a new Lightning last week.
Lifetime, I've now owned 6 EV's, and saved >>$15K on gas savings, oil changes. Tires are more expensive than the electricity. But I drive hard and went through 3 sets of tires on my 1996 Z28 in 2.5 years as a comparison.
