The Grumman KurbWatt was an all aluminum electric powered [1] [6] concept mail truck. [7] [8]
The KurbWatt was designed to replace the Jeep DJ [9] in response to the 1979 oil crisis in an effort to consume less fuel. [1] [10] They were expected to save the United States Postal Service 500,000 gallons of fuel a year. [11]
The KurbWatt was determined to be too small, and because of this never entered mass production. [11]
Approximately 50 KurbWatts were manufactured in total. 40 put into service, and remained in service for about 10 years. 10 were sold to private parties.
The KurbWatt was removed from USPS service in 1992 [7] due to high battery prices and the energy crisis ending.

UPS offers air shipping on an overnight or two-day basis and delivers to post office boxes through UPS Mail Innovations and UPS SurePost, two services that pass on packages to the United States Postal Service for last-mile delivery.
An electric vehicle (EV) is a vehicle whose propulsion is powered fully or mostly by electricity. EVs include road and rail vehicles, electric boats and underwater vessels, electric aircraft and electric spacecraft.
The Grumman Long Life Vehicle (LLV) is an American light transport truck model designed as a mail truck for the United States Postal Service, which has been its primary user since it first entered service in 1986, 38 years ago.

The Iron Duke engine is a 151 cu in (2.5 L) straight-4 piston engine built by the Pontiac Motor Division of General Motors from 1977 until 1993. Originally developed as Pontiac's new economy car engine, it was used in a wide variety of vehicles across GM's lineup in the 1980s as well as supplied to American Motors Corporation (AMC). The engine was engineered for fuel efficiency, smooth operation, and long life, not for performance. Total Duke engine production is estimated to be between 3.8 and 4.2 million units.
The Ford Transit Connect is a compact panel van sold by Ford since 2002. Developed by Ford of Europe, the model line replaced sedan-based vans with a dedicated commercial vehicle platform.

A hybrid electric vehicle (HEV) is a type of hybrid vehicle that combines a conventional internal combustion engine (ICE) system with an electric propulsion system. The presence of the electric powertrain is intended to achieve either better fuel economy than a conventional vehicle or better performance. There is a variety of HEV types and the degree to which each functions as an electric vehicle (EV) also varies. The most common form of HEV is the hybrid electric car, although hybrid electric trucks, buses, boats, and aircraft also exist.
An electric car or electric vehicle (EV) is a passenger automobile that is propelled by an electric traction motor, using electrical energy as the primary source of propulsion. The term normally refers to a plug-in electric vehicle, typically a battery electric vehicle (BEV), which only uses energy stored in on-board battery packs, but broadly may also include plug-in hybrid electric vehicle (PHEV), range-extended electric vehicle (REEV) and fuel cell electric vehicle (FCEV), which can convert electric power from other fuels via a generator or a fuel cell.
A battery electric vehicle (BEV), pure electric vehicle, only-electric vehicle, fully electric vehicle or all-electric vehicle is a type of electric vehicle (EV) that uses energy exclusively from an on-board battery. This definition excludes hybrid electric vehicles. BEVs use electric motors and motor controllers instead of internal combustion engines (ICEs) for propulsion. They derive all power from battery packs and thus have no internal combustion engine, fuel cell, or fuel tank. BEVs include – but are not limited to – motorcycles, bicycles, scooters, skateboards, railcars, watercraft, forklifts, buses, trucks, and cars.

In 2003, Grumman Olson was purchased by the American company JBPCO, which also owned Morgan Corp., the then-largest manufacturer of truck bodies in the United States. Grumman Olson was renamed Morgan Olson in 2004.
