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. The related Sunny Excellents continued until 1976 as PB210 models, at first fitted with a 1.4-litre L14 engine. American market B210s were the first Sunnys to have the larger collision bumpers, due to the USA's safety standards at the time. Other markets continued with the more tightly fitted chrome bumpers. In most markets, the B210 line featured as the only engine option a re-designed A12 engine. As usual for Japan, the wagon (three- and five-door models alike) was marketed as a van for commercial use, where it was only available with the lowest-powered 1.2 engine (VB210). The van, in its lowest standard equipment level, came equipped with a three-speed manual gearbox with a column-mounted shift lever. This chassis formed the basis for the S10 underpinning the Nissan Silvia coupé, which allowed Nissan to sell the Sunny Coupé at two Nissan Japanese dealership networks. The Sunny was exclusive to Nissan Satio Store, while the Silvia was exclusive to Nissan Prince Store, alongside the Nissan Skyline. Facelift (B211) B211 is the chassis code for the minor facelift of the B210, introduced in February 1976. It included a changed grille and other minor changes, such as new wing mirrors and hubcaps. The most important differences were under the hood, where the engines had been upgraded to meet Japan's 1976 emissions standards. The Sunny Excellent now only came fitted with the larger 1.6-litre engine, with the more compact A14 engine replacing the L14 and being installed in the regular bodied model (HB211). The Excellent's chassis code changed from PB210 to
