model had a claimed and a top speed of . The new model was more comfortable than the previous; it had a woodgrain dashboard and other luxuries. Outside Japan it was sold as the B1600 and later as the B1800, which was originally sold only in North America. In the US for the 1980 model year, it was sold as the B2000, which used a 2.0-liter F/MA engine, replacing the B1800. The diesel 2.2-liter B2200 was sold from 1981 with the chassis code UD (introduced during 1982 for the United States). In the US, the 1984 B2000 continued to be sold through 1985; the next generation only appeared as a "1986". The 2.0-liter version was called PE2M6/M7 until 1981—"6" for the short wheelbase, "7" for the long bed—after which it had the chassis code UC. In Japan, this truck was discontinued in October 1979 because commercial customers preferred vans over the less space-efficient, bonneted trucks. The B2000 was also available in a long-bed version with a longer wheelbase and rear overhang, which was given the model name Sundowner in some markets—a reference to nomadic Australian herders who would make camp wherever they were at sundown. The regular model code UC11 was changed to UC21 when it was fitted with a long bed. The chassis coding system was used for the US market in 1981 when a standardized VIN code was introduced. This change led to a second coding system, complicating the identification and grouping of these trucks. The B series was reskinned during 1982, with new sheetmetal below the belt line, and was replaced in January 1985. By this time, 1.8 million Mazda B-series trucks had been built since 1961. In Australia and New Zealand, the Courier was a compact pick-up built for Ford by Mazda in Japan. It was first offered on the Australian market in 1979. Both Mazda and Ford versions for New Zealand were assembled locally. Gulf Auto Restorations in New Zealand also built a run of double-cab Ford Couriers in 1979, long before Mazda themselves developed such a model.
