The P510 (RHD) and PL510 (LHD) were the most prevalent models in many export markets, including the U.S. The 1969 KP510T two-door coupe version arrived in small numbers to right-hand-drive markets, predominantly Japan's domestic market, unsaddled by engine emission regulations. The
K prefix cars are coupés, with a swept roofline and shorter deck lid, while wagons carry a
W prefix. For the 1974 model year, the 510 four-door sedan was dropped in favor of the 1974 PL610 series cars. Around the world, the
J series pushrod-engined model was most common.

Japan 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. The 510-series Bluebirds differed widely depending on the market. In South America, Asia (excluding Japan), and in Africa, the 510 sedan, and two-door models traded rear independent suspension for a leaf-sprung solid axle. (All station wagon models were equipped with a solid axle). The engines for these markets also differed. Rather than the OHC
L-series, they received pushrod inline four-cylinder engines from the
J-series with either 1.3 or 1.5-liter displacement. These variants were also known as Datsun 1500 (J15 engine) and Datsun 1300 (J13 engine). In September 1970, the 1.3 and 1.5-liter engines were replaced with 1.4-liter units. In September 1971 the new, larger,
Bluebird U (610) appeared in Japanese showrooms, but the 510 continued on sale as a lower-priced, more compact version. It also received a minor facelift with plastic surrounds for the headlamps, while the 1800 cc models were discontinued. The chassis code was changed to 510N.
North America Originally only available as a four-door sedan or a station wagon for the 1968 model year, the two-door sedan saw a limited introduction during the summer of 1968 - making this the rarest U.S. 510 year and model. In Canada it was marketed as the
Datsun 1600 rather than using the internal, "510" model code. For 1969, the grille was changed and now has an unpainted, stainless steel central section with rounder bars than those found the year before. The wide "DATSUN" text was replaced with an upright rectangle with a "D" in the middle. The windshield wipers were changed for a more traditional layout and round side marker lights were added at the rear. These cars were very popular for motor sport in South Africa. The cars were used in numerous rallies by Ewold van Bergen from Pretoria, South Africa, who was a test engineer for Nissan Japan. ==Later years==
