Nissan blamed the delay on the "ongoing semiconductor shortages and supply chain disruptions from the spread of COVID-19."
The U.S. launch was originally planned for this spring. Nissan declined to comment on the launch timing for other markets. The overhauled Z car targets mainly the U.S. and Japanese markets.
Nissan announced separately on April 27 that production in Japan plunged 44 percent in the month of March, compared with a year earlier, as the global supply chain crisis dragged on.
CEO Makoto Uchida unveiled the redesigned Z prototype in September 2020 to much fanfare.
The retro-styled sports coupe is a key nameplate in the company's “Nissan A to Z” product blitz, which aims to rejuvenate an aging lineup with a steady stream of new offerings.
The A stands for the new Ariya electric crossover, and the Z is for the new sports coupe.
The Ariya's arrival has also been thrown off schedule.
Deliveries of the full-electric SUV are starting to trickle out in Japan, but the Ariya won't reach the U.S. until the autumn.
Nissan doubled down on the 2023 Z, making the seventh-generation the most powerful in the line's history, a fire-breathing, twin-turbo 3.0-liter V-6 speedster that delivers 400 hp.
Both the Ariya and the Z are made at Nissan's Tochigi assembly plant north of Tokyo. The Ariya is made on a line that was completely revamped to manufacture electric vehicles. The Z is made on a separate line that also churns out the GT-R sports cars and sedans for Infiniti.
Also on April 27, Nissan announced Japan-market pricing of the upcoming Z.
The car will start at ¥5,241,500 ($41,100), including consumption tax, and top out at ¥6,966,300 ($54,600) for the top-grade Proto Spec, with a nine-speed automatic transmission.
