The Nissan Diesel Condor is a line of medium-duty commercial vehicle produced by Nissan Diesel (now UD Trucks), first introduced in 1975. The range was primarily available in other big-size and mid-size trucks. Most mid-size and big-size models of the truck are distinguishable by a front 'Condor' badge, but the common Nissan Diesel or UD badge is usually used on the rear. In the United States, where it is sold as an UD, its principal competitors are Bering MD, Mitsubishi Fuso FK, Chevrolet W-Series, GMC W-Series, and the Isuzu F-Series. Its Japanese market competitors are Mitsubishi Fuso Fighter, Isuzu Forward, and Hino Ranger. In 2011 a new generation Condor MK/LK was introduced, and from now on the UD name is used in all markets, rather than Nissan Diesel.
