Isuzu has had a good name in the diesel engine field for long time and had built 20 million diesels since its predecessor developed Japan's first air-cooled automotive diesel engine in 1936. The company's history is highly respected because of not only its length but also its abundant fruits in responding to ever-changing demands of the market as well as of society.

With its technological edge, Isuzu has kept setting the pace for the industry in developing fuel-efficient, low-emission and powerful diesels. As a result, Isuzu excelled over other companies in the introduction of a direct-injection system and turbocharger incorporated with an intercooler and electronically controlled common-rail high pressure fuel injection system.

If it were not for their excellent reliability and durability, Isuzu diesels could not be used at the Japanese base for the national expedition program in Antarctica, nor could OEM-basis supply of automotive and industrial models to other companies have increased. Isuzu diesels are selected and highly accepted by world-leading automakers around the world, such as Adam Opel in Germany, Saab in Sweden, Renault in France and General Motors in USA. They count on Isuzu for its superior performance and excellent fuel economy.

With this background, Isuzu is now ranked among the world's largest diesel engine manufacturers along with Peugeot-Citroen Group, Renault and Volkswagen. The company currently produces almost one million diesels annually for a wide spectrum of industrial applications as well as for powering vehicles, ranging from a 1,000 cc class unit used in a mini-backhoe to a heavy-duty powerhouse for large tractors.
