Exported as the Datsun 120Y and Datsun B210 (in North America), the third generation (1973–1978) Sunny was extremely popular as it debuted during the 1973 oil crisis. It was first shown on 1 May 1973 in Japan, as the 1.2 or the 1.4-litre Excellent. Both engines were offered in two different levels of output, from the lowest powered 1.2 to the Excellent GX Coupe. Six body styles were offered: the four-door sedan, two-door sedan, two-door fastback, three-door wagon, five-door wagon, and a three-door van. The coupé retained its fastback styling, but now featured a full hatchback door rather than the small trunk lid of the previous generation Sunny. The wagon and van were not offered in North America. In 1975, Japan models were fitted with emission control technology, called Nissan NAPS to be in compliance with Japanese Government emission control regulations enforced that year.
