When first shown, at the 1967 Tokyo Motor Show, Japanese customers received the overhead-camshaft 1.3-liter engine with a claimed - according to Nissan, an engine more capable than competitor Toyota's 1.5-liter version. The little engine was not helped by being married to a three-speed manual gearbox. From the beginning, however, North American customers received the larger 1.6 coupled to a four-speed all-synchro transmission. Indeed, by October 1968 the Bluebird was made available with a 1600 cc engine to Japanese buyers as well. The 510-series Bluebirds differed widely depending on the market. In South America, Asia (excluding Japan) and in Africa, 510 sedan, two-door & station wagon models traded rear independent suspension for a leaf-sprung solid axle. The engines for these markets also differed. Rather than the OHC 1.6l L-series, they received pushrod inline four-cylinder engines from the J-series with either 1.3l or 1.5l displacement. These variants were also known as Datsun 1500 (J15 engine) and Datsun 1300 (J13 engine).
