The first models arrived in August 1978, and seamlessly took over the sales success of the 120Y. The B310 offered the exactly the same body options as before with more interior refinement, but in a squared off body style echoing that of the Violet. The 1397cc version of the A series engine was now offered and supplemented the smaller 1.2 litre unit for all body shapes apart from the Fastback estate. The 1.4 litre coupe version initially featured a 5 speed gearbox, which was curiously deleted from the post 1979 versions. Despite this models relatively short import 20 month run, it sold even more than the previous model. Motoring journalists praised the car for its showroom appeal, reliability and ease of driving would add that the Sunny range was on the whole a conventional design with proven mechanics. This was a relatively common trait in mid sized Japanese cars, but despite the presses reoccuring comments regarding the neutral driving experience, the cars success continued with exactly what people expected of the cars. The 1.2 litre estate version still showed its commercial vehicle roots, sold at a cheaper price with a more austere specification. An additional body shape with semi-hatchback fastback estate version was introduced in mid 1979 and allowed the sunny range to appeal to those who needed a more creature comforts, such as fabric seats, carpets and a more powerful engine. Nissan continued to offer 2 sunny estate models into the UK until 1992. Total UK sales for all B310 models was 114,682.

Early UK versions would still sport 120Y or 140Y badge depending on the engine size, but all models were soon badged as the Sunny, with later models adorning a GL trim level badge. Mechanically similar to the previous model but now with multi-link rear suspension, with exception to the 1.2 litre estate model which retained rear leaf springs. The final RWD incarnation of the sunny was a facelifted model, with an updated instrument panels, rectangle front headlamps, restyled tail lights on the saloon and coupe and a new range of 1488cc engines – the final evolution of the hardy A Series engine. As before the Sunny was also available and imported as a panel van.

The JDM Sunny Excellent, which had previously utilised the L series engines were no longer produced but the equivalent models used the A series engines with fuel injection and were badged as the GX-E or SGX-E. North American Sunny models were badged as the 210, carrying on the previous models name tag. The 3 door estate version also continued in this guise, both with metal rear side panels or glass. The Taiwanese Yue Loong (YLN) company had long been assembling Nissans for their own market, and chose to continue producing the B310 (as the Sunny 303S) well into the 90’s as a budget alternative to the newer Sunny models. These later models also featured styling elements that were not generally available in the rest of the world, with black plastic wrap around bumpers, larger rear lamps and sloping headlamps and grill.
