The Oshkosh NGDV has an estimated battery-electric range of 70 miles.
That figure describes the battery-electric version of the USPS mail truck and is listed as an estimate rather than a guaranteed real-world distance. The electric model uses a 94-kilowatt-hour lithium-ion battery, while other NGDV versions use an internal-combustion powertrain.
The 70-mile figure also connects to the original USPS design requirements. Prototype specifications called for a minimum operating range of 70 miles while completing 600 stops and starts, with heating, air conditioning, and accessories operating under demanding temperature conditions.
Actual range can vary with payload, weather, terrain, traffic, driving style, and use of climate control. That is why 70 miles should be understood as the published estimated figure or design target, not a promise that every route will produce exactly the same result.
