Suburban growth in the 1950s prompted the USPS to motorize city delivery routes and experiment with electric vehicles in their fleet. By the 1970s Jeeps had become the primary delivery vehicles, and the postal service invested in 350 electric Jeeps called “Electrucks”. However, most electric Jeeps were removed from the fleet by 1983. The USPS continued to test other electric vehicles throughout the 1980s.
