"Below this paragraph is a photograph of the Grumman LLV, the main vehicle of the United States Postal Service. It is an icon. It has been the main mail truck in just about every neighborhood I've ever lived in, for my entire life, for a simple reason. Despite the last LLV rolling off the line in 1994three years before I was bornit is still, by far, the most prominent postal vehicle in the country."
"While the General Motors Iron Duke 2.5-liter four-cylinder engine in the Grumman is reliable, it and its three-speed transmission are horrendously inefficient by modern standards. For vehicles that spend a lot of time stopping and starting in cities and suburbs, it's a less-than-stellar choice. And with no air conditioning and a 1980s military contractor's idea of a comfortable cabin, I'm sure your mail carrier is ready to move into something newer."
The Grumman LLV served as the primary USPS mail truck for decades and remains widely visible despite production ending in 1994. The LLV's design prioritized longevity over modern efficiency, relying on a General Motors Iron Duke 2.5-liter engine and a three-speed transmission. Those powertrain choices make stop-and-go city operation inefficient, and the vehicle lacks air conditioning and a modern cabin. Fleet delays forced many departments to buy right-hand-drive commercial vans as stop-gap replacements. The Next Generation Delivery Vehicle (NGDV) is an electrified, long-delayed successor that is beginning to enter service, signaling a transition toward newer, more efficient postal vehicles.
