Mazda B series

The Mazda B series is a series of pickup trucks that was manufactured by Mazda. Produced across five generations from 1961 to 2006, the model line began life primarily as a commercial vehicle, slotted above a kei truck in size. Through its production, Mazda used engine displacement to determine model designations; a B1500 was fitted with a 1.5 L engine and a B2600, a 2.6 L engine.

In Japan, the B-series was referred to as the Mazda Proceed for much of its production, with several other names adopted by the model line. In Australia and New Zealand, the B-Series was named the Mazda Bravo and Mazda Bounty, respectively; South Africa used the Mazda Drifter name. Thailand used the Mazda Magnum, Thunder, and Fighter names. Through its association with Ford, Mazda produced the B-Series as the Ford Courier and the Ford Ranger. Conversely, the Ford Ranger was sold in North America as a Mazda B series from 1994 until 2010.

In 2006, the Mazda B-Series was replaced by the Mazda BT-50.

Mazda's first vehicles were three-wheeled trucks, also known as auto rickshaws, starting with the 1931 Mazda-Go and followed by the Mazda K360 in 1959, the Mazda T1500 [ja], and finally the larger Mazda T2000 [ja]. One of Mazda's first four-wheeled trucks was the 1958 D1100, briefly called the Mazda Romper [ja], with a 1105 cc air-cooled in-line two cylinder engine installed under the seat. That engine was replaced by a water-cooled unit in 1959 and joined by the larger capacity D1500. In 1962, passenger car size requirements no longer applied to commercial vehicles and the truck grew longer, with a two-liter D2000 model becoming available while the smallest D1100 was discontinued. The D1500 and D2000 remained in production until the June 1965 introduction of the Mazda Kraft.

The Mazda B-series pickup truck was introduced in Japan in August 1961 as the B1500 (BUA61). This model was the only Japanese market model to be badged under the B-series naming scheme, i.e. B1500. The BUD61 (second generation) that followed was the first model of the long-running "Proceed" series sold in Japan. It had a 1,484 cc OHV water-cooled engine with wet sleeve cylinders which produced 44 kW (59 hp; 60 PS), and a one-ton payload. This model also had a torsion bar front/leaf spring rear suspension, which was advanced for its time, giving it a relatively smooth ride. The B1500 was remodeled between late 1962 and September 1963; it received a new chassis code, BUB61. The BUB61 was more spacious; its cabin was extended by 80 mm (3.1 in) and it had a stretched body and wheelbase. The BUB61 had a new, upside-down, trapezoidal grille instead of the earlier full-width unit, with thirteen bars rather than nine, turn signals on the fenders, and more chrome trim—including a decor strip on the side.

In addition to the standard two-door "styleside" pickup truck body there were also a double-cab truck, and a similar double-cab version called the "pickup." The "pickup" had a fully integrated coupé utility body rather than the separate bed of the truck version, as it was based on the somewhat passenger-oriented light van. This model was a two-door, fully glazed van with a fold-down tailgate and an electrically powered window, which was rare in the Japanese market at the time. The light van (BUAVD) was introduced in September 1962, and the two double-cab models followed shortly after. These three models were built on the shorter wheelbase chassis; when the longer chassis was introduced it was not deemed worthwhile to create new bodywork. These models were produced for only a few months. The B1500 was sleeker and considerably more powerful than its competitors in the Japanese market, but it was also markedly more expensive and it failed to sell in the expected quantities.

The 1966 B1500/Proceed presented in October 1965 used the same 1484 cc OHV I4 engine as its predecessor, with minor changes to the cylinder head and valves and the use of a downdraft carburetor instead of the sidedraft unit used on the models sold between 1961 and 1965. The UA engine now produced 72 PS (53 kW) at 5200 rpm. The chassis was now called the "BUD61"; it was longer than its predecessor and received new bodywork of a squarer design, and four headlights. In January 1971, a 1600 cc model with the chassis code BNA61 was introduced. This had 95 PS SAE in global markets; US brochures did not specify its power output and European importers claimed 75 PS DIN (55 kW). In Japan, 100 PS (74 kW) (SAE gross) was claimed; the model was advertised in Japan as the "GT-Truck".

In March 1972, the Proceed 1300, with a smaller 1.3-liter engine, was released and remained available in Japan until 1975. It had 87 PS (64 kW) in SAE gross. The B1500 was the first Japanese pickup truck to be assembled in New Zealand from CKD kits. Assembly started in 1967 at Steel's Motor Assemblies after a government order for 672 units; Steel's also built the Toyota Corona and later became Toyota New Zealand's Christchurch plant. The model remained in local assembly at various plants for several generations.^{[citation needed]}
