In February 1972, the Datsun 620 truck was launched and was in production until 1979. It was a regular cab truck (in 1977 a longer version of “King Cab” was released [Nissan’s trademark for its extended cab trucks] ) and two wheelbases were offered, for a total of six different models. There was also a delivery van version, which is offered only in Japan. Naturally, there were bare-chassis models and many importers installed locally made flat platforms. There was also the U620, which is a double cab “Utility” version. It uses a shorter, fully integrated bed to allow four people to sit comfortably. The U620 was essentially a 620 pickup from the doors forward, the bed and rear being the only difference. Nissan continued the strong rhythms and styling of its previous vehicles, with a “wingline” accent on the shoulders or “Bullet Side” throughout the vehicle. In most of the world, the 620 was equipped with the J15, producing 77 horsepower (57 kW) and a declared top speed of 135 km / h (84 mph). A 2.2-liter diesel engine with 66 horsepower (49 kW) was subsequently made available in many markets.

The 620 was also the first Datsun pickup truck available with a longer “King Cab” passenger compartment (called “Custom” in Japan). This used the regular 620 bed, but has a 10-inch long cab, all set on the longest wheelbase.

The 620 was slightly redesigned for 1978, with changes to the grille and front bumper. The suspension was also revised, increasing the track at both ends by 30mm (1.2 inches). This also marked a name change in South Africa, where it had been sold simply as the Datsun one-ton pickup, to “Datsun 680.” A four-door crew cab variant was also offered in some markets.

North America

In North America, the 620 continued to use the Nissan L engine. The 1972 and 1973 models were powered by the L16 engine (96 hp), the 1974 model used the L18 engine (100 hp), and the 1975 through 1979 models used the engine. L20B (110 hp SAE Gross). [Citation needed]) SAE net rating was 97 hp (72 kW). This was a “50-state car,” with an EGR system for pollution control that was sufficient to meet California’s stringent emissions standards without a catalytic converter. The 620 was available with two wheelbases and also as the 1977 Extended King Cab model. In Canada, the 620 was marketed as “Sportruck” while it was known to American buyers as “The Little Hustler.” In North America it was generally treated like a normal car, with 40% of buyers saying they never used the truck for “work.” Standard transmissions were the four-speed F4W63 (1972 and 1973) and the four-speed F4W71 (1974 to 1979). In 1977, the optional FS5W71B five-speed manual transmission became available. The 3N71 three-speed automatic was available as an option in mid-1972. This was the first series to offer an automatic transmission as an option (all pre-620 model series only had manual transmission). Final drive gear was 4.375: 1.

The side badges say “DATSUN 1600” or simply “DATSUN”. The grille badge had two colored stripes (one red and one blue) behind the word “DATSUN.” The 620 was known for its durability and weatherability despite its small size, along with engines known for their reliability. As a result, the 620 was competing with the larger American pickup trucks, which in turn gave Datsun a solid reputation in the United States. [citation needed] Several innovations were introduced with the 620: first long bed (1975), first extended cab (1977), front disc brakes (1978) and electronic ignition (1978).
