M1 armored car

It could reach a speed of 55 mph (89 km/h) on paved surfaces, and had an estimated cruising range on roads of approximately 250 miles (400 km).

The spare wheels were mounted on free-spinning "stub axles" in an effort to keep it from bottoming out the chassis ("bellying"),[4] but they did nothing to help it get unstuck.

Although the vehicle itself was not adopted for mass production, it showed enough benefits over continued use of the horse to warrant further study and experimentation at mechanizing the U.S. Cavalry through the rest of the 1930s and into the early 1940s.

Lessons learned in its trials also led to the design and adoption of more successful armored cars, such as the T17 Staghound and M8 Greyhound.

The lessons learned about its cross country performance were a factor in the eventual adoption of light tanks and half-tracks for many mechanized cavalry and recon units in the early 1940s.
