Wikipedia has a lot more detail regarding the different variants of this truck:
Drivetrain
There are four planned variants: either an internal combustion engine or battery-electric powertrain, both of which will have options for either two- or four-wheel drive.[5] The 2WD ICE model will have 4,112 purchased parts; the 4WD ICE model has 3,995 parts in common with the 2WD ICE model, while BEV variants have 3,297 and 3,196 parts in common with the 2WD ICE for the 2WD and 4WD BEV models, respectively.[1]
Either powertrain option can be built for future orders, and models with an ICE can be converted to battery-electric if required.[54] Ford has been announced as the drivetrain subsystem supplier, including engines, traction motors, and transmissions.[88] Ford Component Sales also will provide Oshkosh with key parts for suspensions and other components, including cabin interiors.[89] The earlier Oshkosh prototype evaluated during testing was based on the Ford Transit van.[84][85]
The ICE will be a Ford EcoBoost 2.0L turbocharged 4-cylinder gasoline engine.[1] At CES 2022, the video display accompanying the NGDV display showed specifications for the EcoBoost and 8-speed automatic transmission that will be used in the ICE-drivetrain variant. The EcoBoost has a peak output of 250 hp (190 kW) at 5,500 RPM and 275 lb?ft (373 N?m) at 3,000 RPM, but this was de-rated to 206 lb?ft (279 N?m) for reliability.[1]
The electric variant has a Bosch-sourced eAxle drive unit[90] and a 94 kW-hr lithium-ion battery using nickel-manganese-cobalt chemistry.[2]:?Table 3-1.3? The eAxle drive unit is a traction motor with an integrated reduction gearbox and inverter. The permanent magnet AC traction motor has a peak output of 150 kW (200 hp) and a continuous output of 70 kW (94 hp); power is supplied to the wheels through the gearbox with an 11.8:1 ratio. The inverter uses silicon IGBT circuitry.[90]
Fuel economy and range
The internal combustion engine (ICE) variant has an estimated fuel efficiency of 14.7 mpg?US (16.0 L/100 km), decreasing to 8.6 mpg?US (27 L/100 km) when the air conditioning is on.[91][2]:?Table 3-1.2? For comparison, the earlier LLV (built 1987–94) and FFV (2000–01) have an average observed fuel consumption of 8.2 and 6.9 mpg?US (29 and 34 L/100 km), respectively.[2]:?Table G-1? The minuscule improvement in fuel economy was criticized by the United States Environmental Protection Agency (EPA) in February 2022.[63]
The BEV variant has an estimated range of 70 mi (110 km) and a computed consumption of 1.34 kW?h/mi (25.2 mpg?e).[2]:?Table 3-1.3? Although using the air conditioner was not expected to affect the range, using the heater was expected to reduce range by up to half.[2]:?3–2,?3–3? Based on the typical distance driven, it was assumed that only 20% of the battery state of charge would be used each day for most NGDVs; analysis of USPS mail carrier routes demonstrated the all-electric variant's range could accommodate 95% of all routes.[2]:?3–2,?3–3?
Dimensions and capacities
A prototype shown at CES 2022 was 9.5 ft (2.9 m) tall, 19.6 ft (6.0 m) long, and 7 ft (2.1 m) wide.[5] The rear cargo opening measures 49.5 in (1,260 mm) wide and 72.5 in (1,840 mm) tall.[1]
The gross vehicle weight rating of the NGDV with an ICE, including payload, is 8,501 lb (3,856 kg),[2]:?Table 3-1.2? just one pound over the EPA's threshold to be considered a heavy-duty truck, allowing it to avoid more stringent pollution emissions and efficiency standards for light-duty trucks.[91] The estimated curb weight of the NGDV is 5,560 lb (2,520 kg) for the version with a conventional ICE and 6,670 lb (3,030 kg) for the battery-electric vehicle (BEV) variant. The payload of the vehicles also varies slightly, either 2,941 lb (1,334 kg) for the ICE or 2,207 lb (1,001 kg) for the BEV.[2]:?Tables 3-1.2 and 3-1.3?
Safety features
The NGDV is equipped with a second sliding curbside door that allows the mail carrier to enter the cargo area directly, allowing them to avoid having to stand in the street while loading and unloading the vehicle. As another measure for safety, the NGDV has an automatic parking brake that engages when the vehicle is shifted to park, when the driver leaves the seat, or when the ignition is shut off; it disengages when the vehicle is started and then shifted to drive or reverse, and the vehicle ignition is operable only when the transmission is in park or neutral.[17] The front and rear bumpers are equipped with proximity sensors that start beeping intermittently when objects are detected within 8 ft (2.4 m), and switch to continuous alarming when objects are within 6 in (150 mm).[17]
