The Oshkosh Next Generation Delivery Vehicle (NGDV) is a mail truck for the United States Postal Service (USPS).

[9] On February 13, 2015, it was announced that General Motors was actively pursuing this new contract, which would have them provide the USPS with 180,000 new vehicles at a cost of at least $5 billion.

[13]: §3.5  The minimum sustained road speed was 60 mph (97 km/h) with a grade of up to 1% at an altitude of 3,000 ft (910 m) or less,[13]: §4.1, 4.3  with a minimum operating range of 70 mi (110 km) including 600 stops and starts[13]: §3.4  while using the heating and air conditioning systems and accessories at their maximum settings,[13]: §3.4  to maintain cabin temperatures of 65–85 °F (18–29 °C) when ambient temperatures are −30–120 °F (−34–49 °C).

The prototypes represented a variety of vehicle sizes and drive configurations, in addition to advanced power trains and a range of hybrid technologies.

[20] With testing complete, USPS met with the manufacturers and the National Association of Letter Carriers (NALC) to finalize the specifications, which were issued in June 2019.

[19] Utilimaster withdrew from the competition in February 2017,[28] and London Electric Vehicle Company, which was supplying powertrain technology to AM General, announced in December 2018 they would not participate past the prototype stage.

[38] USPS placed its first order in March 2022, at a contract value of $2.98 billion, for 50,000 NGDVs, of which at least 10,019 will be the battery-electric variant;[39] the average per-unit cost of an NGDV is about $59,600.

[43] In June 2021, Oshkosh stated that after a long search, the company will assemble the new mail truck at a new, dedicated factory in Spartanburg, South Carolina, and will employ more than 1,000 local non-union workers.

[44] In Spartanburg, Oshkosh Defense is refitting a large warehouse at the Flatwood Industrial Park that previously was used by Rite Aid as a distribution center;[45] when complete, the building will be used for NGDV production.

[47] The announcement that production would take place in South Carolina using non-union labor was criticized as a bait-and-switch scheme by multiple politicians who had expected the vehicles to be built by unionized workers[48] in Oshkosh's home state of Wisconsin.

[49][50] Senator Ron Johnson (R-WI) declined to challenge the company to relocate production to his home state: "It's not like we don't have enough jobs here in Wisconsin.

Hintz concluded that "if two years pass and there's nothing in [Foxconn's] million-square-foot facility when we could have been producing postal trucks, you know, under this contract, we'll look back at it as a missed opportunity.

[47] Shortly after the contract was awarded to Oshkosh in February 2021, Postmaster General Louis DeJoy appeared before the United States House of Representatives, where he testified only 10% of the planned NGDVs would be battery electric vehicles (BEVs).

[58] At approximately the same time, President Joe Biden issued Executive Order 14057 in December 2021, which mandated that all light-duty vehicles purchased for U.S. government fleets must be BEVs starting in fiscal year 2027, and by 2035, all new federal fleet vehicle procurements, including heavy-duty trucks, must be BEVs.

[60] Researchers at the University of Michigan's School for Environment and Sustainability found the EIS underestimated lifetime emissions associated with the split 10/90 NGDV scenario, and overestimated lifetime emissions associated with the all-BEV NGDV scenario, providing even greater benefits for pursuing the all-electric procurement.

[66][67][68] The USPS and Oshkosh defended the NGDV procurement plan, noting that ICE-powered versions have been designed to be converted to BEV powertrains if required.

[70] Other groups joining the criticism included the EPA, the Biden Administration,[71] Zero Emission Transportation Association, climate activists, and the Congressional Progressive Caucus of the Democratic Party,[69] collectively criticizing Oshkosh and the United States Postal Service for ignoring Executive Order 14057 and proceeding with the 10/90 split procurement.

[73] During the May 2022 National Post Forum, the USPS confirmed that it will increase the number of BEV NGDVs in the initial order.

[79][80] Preproduction versions were shown at the Consumer Electronics Show in Las Vegas for 2022[5] and again for 2023,[81] where attendees could participate in "Operation On-The-Move", a three-player competitive video game to deliver packages.

[7][85] Described as the 'duck-billed option', Oshkosh's NGDV has been designed to maximize interior volume and outward visibility for drivers who will be required to move against traffic in pedestrian-heavy areas.

Current-generation automotive safety features employed by the design include airbags, a 360-degree camera, automatic emergency braking, and collision avoidance systems.

[89] There are four planned variants: either an internal combustion engine (ICE) or battery-electric vehicle (BEV) powertrain, both of which will have options for either two- (2WD) or four-wheel (4WD) drive.

[1] The electric variant has a Bosch-sourced eAxle drive unit[92] and a 94 kW-hr lithium-ion battery using nickel-manganese-cobalt chemistry.
