The U.S. Postal Service plans to replace up to 180,000 aging mail trucks over the course of seven years.
That would be an estimated $6.3 billion of business for the five ventures competing to win the giant contract. Already full-scale testing is underway of the prototype delivery vans from which the post office will make its selection.
We have captured photos of three of the five vans, which include an electric vehicle, hybrids and more conventional trucks. Take a look. One of these is likely to be carrying mail in your neighborhood in the next year or two.
