UD - Ultimate Dependability

 UD, which stands for Ultimate Dependability, became the new brand since the abbreviation was already recognized by customers, who call the vehicles UD products. The UD name is widely known since the letters are engraved in the emblem, which since the 1950s, has been located on both sides of the vehicles. In conjunction with this change, the name of the company was changed from Nissan Diesel Motor Co. Ltd to UD Trucks Corporation.
