Isuzu Motors Limited is one of the world's largest manufacturers of medium and heavy duty trucks.

Isuzu introduced the first air-cooled diesel engine in 1936, the first two-ton low cab forward truck in 1959, the first direct-injection diesel engine in the 1960s, and the first gas engine NPR in 1992. The first American-made Isuzu F-Series Isuzu truck rolled off the Janesville, Wisconsin assembly line in 1996.

These achievements have helped make Isuzu the #1 selling low cab forward truck in America. The Isuzu F-Series was ranked the best cab-over medium duty truck in customer satisfaction for 1997.
