Sales of the Nissan Z-cars (internally also called S30 or Z29) started in October 1969 (for the 1970 model year), with separate versions for the Japanese and U.S. markets. The Japanese Fairlady Z featured a 2.0L [[Overhead camshaft#Single overhead camshaft|SOHC]] L20A [[straight-six engine]] producing {{convert|130|hp|kW|0|abbr=on}}, while the US Datsun 240Z featured a 2.4L L24 inline-6 with twin [[Hitachi]] [[SU Carburetter|SU-type]] [[carburetor]]s that produced {{convert|151|hp|kW|0|abbr=on}} ([[Horsepower#SAE gross power|SAE gross horsepower]]). A third Z, the [[Nissan S30#Fairlady Z432|Z432 (PS30)]] shared a performance version of the [[Overhead camshaft#Dual overhead camshaft|DOHC]] 2.0&nbsp;L [[Nissan S20 engine|S20]] engine with the [[Nissan Skyline GT-R#First generation (1969–1972)|Nissan Skyline 2000 {{nobr|GT-R}}]].

In Japan, the Z was still known as the Fairlady to keep the car in line with the previous generation [[Datsun Sports]] roadster. [[Japanese domestic market]] (JDM) versions had the Fairlady Z badge on the lower fenders with the 432 badge above (the 432 designation was 4 valves, 3 carburetors, and 2 camshafts). However, Yutaka Katayama ensured the American version had all Nissan, Fairlady Z, and 432 badging replaced with "[[Datsun]]" and prevented all dealer shipments until they were replaced.<ref>{{cite news|url=http://www.zccc.org/wp-content/uploads/2013/12/112009.pdf|title=The Odometer |date=2009|publisher=The Official Newsletter of the Z Car Club of Colorado Established 1983}}</ref>

The 240Z was released in America on October 22, 1969. It sold over 45,000 units through the '71 model year and over 50,000 and 40,000 in 1972 and 1973, respectively.

The 260Z was released in 1974. Engine displacement increased to 2.6 L, and Nissan introduced a [[2+2 (car body style)|2+2 model]] option with a 30&nbsp;cm (1 foot) stretched wheelbase and length. Engine power increased to {{convert|154|hp|kW|0|abbr=on}}, except for most areas of the U.S., where power decreased to {{convert|139|hp|kW|0|abbr=on}} ([[Horsepower#SAE net power|SAE net horsepower]]) due to new camshafts, carburetors, and lower compression, that were introduced to comply with new US emissions regulations.

The 280Z was released in 1975 for North America only (not to be confused with the second-generation [[Nissan 280ZX|''280ZX'']]) and featured a further engine displacement increase, to 2.8 L. A&nbsp;major change was the introduction of [[Robert Bosch GmbH|Bosch]] [[fuel injection]], replacing the previous SU carburetors. This resulted in a power increase to {{convert|170|hp|kW|0|abbr=on}} ([[Horsepower#SAE gross power|SAE gross horsepower]]), offsetting increased weight from added luxury features and an enlarged [[Bumper (automobile)|bumper]] that met US Federal regulations. Export markets outside North America however kept receiving the Datsun 260Z, until the introduction of the Datsun 280ZX in late 1978.
