About UD Trucks in North America
UD Trucks ā formerly known as Nissan Diesel Motor Co., Ltd. ā was founded in Japan in 1935 as Minsei Diesel Industries. The company became a Nissan subsidiary in 1950 and was renamed Nissan Diesel in 1952. UD trucks began entering the North American market in the mid-1980s, sold under the UD model designation that indicated approximate payload capacity. The brand was well known in the U.S. under the “Nissan Diesel” name before formally rebranding to UD Trucks on February 1, 2010.
Volvo Group acquired a controlling stake in Nissan Diesel in 2007 and completed full ownership in subsequent years. UD Trucks is now a wholly owned Volvo Group company ā a sibling brand to Volvo Trucks and Mack Trucks. The North American market for UD trucks declined significantly after 2010 as Isuzu’s NPR/NQR/NRR lineup and Hino’s conventional cab trucks captured the Class 4ā7 market. UD’s North American presence is now limited to parts and service support for the legacy fleet ā new UD trucks are not currently sold through a U.S. dealer network.
UD Model Numbering System
UD trucks in North America were named using a four-digit number that indicated approximate GVWR in pounds, rounded to the nearest hundred:
- UD 1200 ā approximately 12,000 lbs GVWR ā Class 3
- UD 1300 ā approximately 13,000 lbs GVWR ā Class 3ā4
- UD 1400 ā approximately 14,500 lbs GVWR ā Class 4
- UD 1800 / 1800 CS ā approximately 18,000 lbs GVWR ā Class 5
- UD 2000 ā approximately 20,000 lbs GVWR ā Class 5ā6
- UD 2300 / 2300 DH / 2300 LP ā approximately 23,000 lbs GVWR ā Class 6
- UD 2600 / 2600 LP ā approximately 26,000 lbs GVWR ā Class 6ā7
- UD 2800 ā approximately 28,000 lbs GVWR ā Class 7
- UD 3000 ā approximately 30,000 lbs GVWR ā Class 7
- UD 3300 ā approximately 33,000 lbs GVWR ā Class 7
UD & International ā The Navistar Connection
For a period in the 1980s and 1990s, Navistar International purchased and sold rebadged UD (Nissan Diesel Condor) trucks as the International 400, 500, 600, 700, and 900 Series ā with the largest Model 900 corresponding to the UD 3300. This arrangement gave UD trucks a second sales channel through International’s extensive North American dealer network. Buyers may find these trucks badged as either UD or International with identical mechanical specifications. We purchase all rebadged International/UD trucks in any condition.
UD Engine ā The Nissan Diesel FE6
The majority of North American UD trucks from the 1800 through the 3300 are powered by the Nissan Diesel FE6 inline-six turbodiesel ā a 6.9-liter engine available in naturally aspirated and turbocharged variants producing 160 to 230 HP depending on configuration. The FE6 is known for its durability and relatively straightforward maintenance compared to later common-rail engines. Lighter models (1200, 1300, 1400) use smaller Nissan Diesel four-cylinder engines. Parts availability for the FE6 remains reasonable through Nissan Diesel/UD parts suppliers in North America.
