The Nissan S30 (sold in Japan as the Nissan Fairlady Zebra and in other markets as the Datsun 240Z, then later as the 260Z and 280Z) was the first generation of Z GT two-seat coupe, and later (beginning in the 1974 model year) also 2+2 hatchbacks produced by Nissan Motors, Ltd. of Japan from 1969 to 1978. It was designed by a team led by Mr. Yoshihiko Matsuo, the head of Nissan's Sports Car Styling Studio. HLS30 was the designation of the left-hand drive model and HS30 for the right-hand drive model.
All variants had a 4-wheel independent suspension consisting of MacPherson struts in front (borrowed from the Nissan Laurel C30) and Chapman struts in back. Front disc brakes and rear drums were standard.
The 240Z and 260Z used twin, variable venturi Hitachi one-barrel side-draft SU-like carburetors. The carburetors were changed beginning with model year 1973 to comply with emissions regulations, but the earlier carburetors were far superior for performance. Fuel injection (L-Jetronic electronic fuel injection, designed by Bosch) was added for the 280Z in 1975 for the US. This was primarily in order to cope with the difficulty faced in getting enough power using carburetors while still meeting US emissions regulations.
Due to its relatively low price compared to other foreign sports cars of the time (Jaguar, BMW, Porsche, etc.), it became popular in the United States and was a major success for the Nissan Motor Corporation, which at the time sold cars in North America under the name Datsun. The 240Z also broadened the image of Japanese car-makers beyond their econobox success.
Continuing through the 1975–1978 model years, other non-USA markets still received the 260Z coupe and the 260Z 2+2 hatchback — the two-door, four-seat model. The S30 240Z is essentially unrelated to the later 240SX, which is sold as the Silvia in Japan, although initial advertising for the 240SX mentioned the S30.
