The 1970 240Z was introduced to the American market by Yutaka Katayama, president of Nissan Motors USA operations, widely known as Mr. K. The early 1970 model 240Z had a chrome "240Z" badge on the B-pillar quarter panel. Two vents were included in the rear hatch below the glass molding. In mid-1971 the B-pillar side badges were restyled with the letter Z vent, and the vents were eliminated from the hatch. Design changes for the U.S. model occurred throughout production.
The 1970 models were introduced in October 1969, received the L24 2.4 litre engine and a 4-speed manual. A less common 3-speed automatic transmission was optional from 1971 on, and had a "Nissan Full Automatic" badge.
In 2004, Sports Car International named this car number two on the list of Top Sports Cars of the 1970s. One of the most appealing Japanese cars ever produced, it nevertheless disappeared almost entirely from American roads within two decades, presumably because like most Japanese cars of the time it had insurmountable rust issues.
