USPS spokesperson Kimberly Frum told me that the agency “cannot comment on which companies are vying for the NGDV contract, their potential subcontractors, team members, or any other details.”
So we don’t know much about the trucks or companies being considered, through Trucks.com (a trucking and automotive news site) published a piece back in September 2019 that identified four companies that competed in the prototype phase. Only two of them had all-electric trucks.
In selecting a manufacturer, Frum said, “The Postal Service will make a choice based on an evaluation of best value,” which could include everything from durability to features to total cost of ownership.
Here’s the thing: On a full life-cycle basis, electric vehicles are absolutely a better value.
An electric motor converts electricity into motion more efficiently (around 90-95 percent) than an internal combustion engine (ICE) converts gasoline or diesel (40-45 percent at the high end, much lower in average use). That’s mainly because combustion engines produce an enormous amount of waste heat, whereas electric motors produce virtually none.
