The is buying 9,250 by the end of this year as the agency embarks on the electrification of the largest federal fleet in the U.S. Deliveries of the mail trucks are due to begin in December of 2023, and the will represent one of the first major milestones in the USPS’ effort to transition away from .

It’s strange, then, that the is also buying an equal amount of mail trucks from Stellantis: namely, 9,250 Ram ProMaster delivery vehicles that run on gasoline not .

It seems change won’t happen overnight, after all, so the USPS is bolstering its next-gen fleet of Ford E-Transit EVs with a 1:1 ratio of Ram ProMasters — for now. The order for all 18,500 new delivery vehicles will cost the USPS just over $1 billion, according to .

The post will also be awaiting delivery of its other NGDV models, which are pending a contract from .

Slowly but surely, the USPS will electrify its fleet. The long process is expected to cost $9.6 billion within the next five years. And nearly one third of that money will come from the Inflation Reduction Act, which will grant the USPS $3 billion to transition to EVs.
