In 1935, Kawaguchi, Japan & Nihon Diesel Industries Ltd is established. In its original inception, the company produced 2-cycle diesel engines. In 1940, production of the 4.5-ton-payload TT6 truck began setting the foundations for the brand we currently know as UD Trucks. The Nihon Diesel Industries is also responsible for bringing the first monocoque-type buses to the Japanese market, the BR3 series with rear-mounted engines.
After one other name change (Minsei Diesel Industries, Ltd) the name of the company was changed to Nissan Diesel Motor Co Ltd, in 1960. It was during this time that Forward-control trucks and truck tractors were introduced into the market. The 60’s also saw the introduction of 4-cycle 40kW (55PS) SD20, 44 kW (135 PS) SD22, 99 KW (135 PS) ND6, 136 kW (185PS) PD6 diesel engines and 70 to 80-ton crane-carrier trucks to the company’s product offering.
In 2000, new heavy-duty trucks were introduced by Nissan Diesel and the Nissan Diesel Sales Co Ltd operation was acquired. 2007 saw the company being bought by Volvo Group and the introduction of the UD Trucks moniker to Nissan Diesel. In 2010, Nissan Diesel changed its name to UD Trucks, a name that has become synonymous with dependability within the trucking industry.
