description UD Trucks Overview
UD Trucks, formerly Nissan Diesel, is a Japanese heavy-duty truck manufacturer now part of the Isuzu-Volvo partnership. Known for its Quon series and Croner medium-duty trucks, UD Trucks emphasizes fuel efficiency and driver comfort. In 2025, UD Trucks continues to offer robust diesel engines with advanced telematics for fleet management. The brand has a strong presence in Japan and Southeast Asia, particularly in the heavy-haulage segment.
