The U.S. Postal Service (USPS) announced in February 2021 that it has awarded Oshkosh Defense an indefinite delivery, indefinite quantity (IDIQ) contract to produce the Next Generation Delivery Vehicle (NGDV), the USPS’s first large-scale fleet procurement in three decades. The competitively awarded contract allows for the delivery of between 50,000 and 165,000 vehicles over a period of 10 years.

The contract includes both zero-emission battery-electric (BEV) and fuel-efficient low-emission internal combustion engine (ICE) vehicles, with the ability to deliver any combination of NGDV vehicle orders. Both Oshkosh Defense’s ICE and BEV models offer a significant improvement in fuel efficiency and emissions over the Long-Life Vehicle (LLV) models they will replace. Additionally, the Oshkosh Defense NGDV offers the USPS the flexibility of both low-emissions internal combustion engines and zero-emission battery-electric powertrains on a single chassis. A significant design feature allows the USPS to be able to retrofit any internal combustion engine NGDV with a battery-electric powertrain to capture advances in electric vehicle technologies.

Already proven effective on the Oshkosh® Heavy Expanded Mobility Tactical Truck (HEMTT) A3 and Medium Tactical Vehicle Replacement (MTVR), ProPulse® technology uses a modular series-hybrid arrangement to simplify the transmission of power to the wheels. Its diesel engine powers a large electric generator distributing power to each axle module, which is driven independently by a dedicated motor controlled from its own power converter. And life-cycle costs are dramatically reduced because the full electric system lowers torque throughout the drivetrain and regenerative braking increases brake life.

ProPulse® hybrid diesel-electric system enables significant fuel economy because of a tailored engine control strategy.
•% Fuel economy improvement over conventional driveline vehicle (preliminary Oshkosh internal test data)
•+35% at 20 mpg (32 kph) cruising speed
•+20% at 60 mph (96.5 kph) cruising speed
•+30% start/stop (0-25 mpg; 0-40 kph)

The Oshkosh Defense® Light Combat Tactical Vehicle (LCTV) incorporated early advancements in the TAK-4® independent suspension system and ProPulse® diesel-electric system. The diesel-electric powertrain delivers improved fuel economy and exports significant levels of electrical power. Read more on ProPulse® above.

With these technologies, the LCTV was the world’s first armored military vehicle to successfully endure the extreme terrain of the SCORE Baja 1000 off-road race in November 2010. The Baja 1000 is a 1,050-mile race across the Baja California Peninsula. The LCTV accomplished what nearly 40% of racers failed to do – complete the challenging course.
