1970Nissan Z
The original Z — sold in the US as the Datsun 240Z (1970–1973, 2.4L L24 six), then 260Z (1974, 2.6L, added a 2+2) and 280Z (1975–1978, 2.8L fuel-injected). A long-hood fastback that made affordable performance a mainstream idea.

The 1970 model year
Overview
The Datsun 240Z launched in the US in late 1969 as a 1970 model and was an instant phenomenon: a long-hood, fastback sports coupe with an inline-six, independent suspension, and styling that rivaled far costlier European GTs, all at an accessible price. It reset expectations for Japanese performance cars in America.
