The full block from TFA:
An electric truck is already a step up in efficiency and environmental responsibility from traditional internal combustion trucks, with a delivery cost to the shipping company of 30 cents per mile (compared to roughly a dollar per mile with diesel).
they're claiming a 70% cost reduction by going to an electric truck. Same driver, same parcel load, same mileage, ect...
Which would imply that their Diesel fuel + Diesel specific maintenance costs them 70 cents per mile MORE than their electricity and electric specific maintenance.
If they can put that same driver in an electric vehicle and do the same deliveries for 30 cents a mile, I'm thinking that they are doing something really wrong with the Diesel vehicles.
The big wear and tear that they will see over my horse truck is brakes. But even if you figure they drop $1000 on rotors, pads, and labor for brake jobs, every year, they're still putting probably 50k miles a year on those trucks. Which works out to be 2 cents per mile. And that's the hardest hit area.
You could toss in the tranny (although it should be holding up for much more than a single year of stop and go). But even if they're only getting 1 year out of a tranny, and they drop $5k for a new tranny installed each year, that's still only 10 cents a mile.
Suspension, power steering, tires, etc... would all be taking the same abuse whether you're in a Diesel or an electric.
To be spending $0.70/mile on a vehicle putting down 50k+ miles a year, means spending over $35,000 a year on vehicle maintenance.
To put that into scope, a Ford e-350 stripped chassis (your basic commercial delivery frame) MSRPs for $25,000. Jump up to an e-350 cutaway (your standard UHaul truck) for $30,000. Even if they blow $15k on a custom cab/body, you're still looking at a $40,000 vehicle. How the heck are they blowing over $35,000 a year maintaining a $40,000 vehicle?
