Sales of the Nissan Z Car started in October 1969 (for the 1970 model year), with separate versions for the Japanese and U.S. markets. In the US it was marketed as the Datsun 240Z, and featured a 2.4L L24 inline-6 with twin Hitachi SU-type carburetors that produced 151 hp (113 kW) and drove power to the rear via a four-speed manual. A less common three-speed automatic transmission was optional from 1971 on. JDM versions were known as the Nissan Fairlady Z. Combining good looks, and powerful performance, it sold over 45,000 units through the '71 model year and had similar sales the next two years, respectively. For the 1974 model year, the 240Z was replaced by the Datsun 260Z.
