The second-generation Sunny was launched in 1970 and was also known as the Datsun 1200. The Datsun 1200 featured MacPherson strut front suspension with optional disc brakes and an economical 1.2-litre A12-series engine. A five-door station wagon was added to the Sunny range in addition to the three-door wagon.
In April 1970 a GX Grand Luxury trim with twin-carburettor engine was added for the Japanese market. In January 1972 a minor facelift occurred in the Japanese market with a new hood, grille and other small modifications and equipment fitting. In August 1972 the GX-5 model was added in Japan, which improved on the GX by fitting a direct-fifth (non-overdrive) five-speed manual transmission.
The Datsun 1200 was the most fuel-efficient vehicle in the United States in 1973, as rated by the government at 28.7 mpg US (8.2 L/100 km; 34.5 mpg imp) in overall driving pattern. It achieved 37.9 mpg US (6.21 L/100 km; 45.5 mpg imp) in highway driving.
In South Africa, the B110 was sold through 1976. A pick up (bakkie) derivative, featuring a 1400 cc engine, was sold until 2008 when emissions laws forced the end of its production. Over 275,000 were sold to customers who appreciated the rugged rear-wheel-drive design
In New Zealand, a special edition Datsun 1200 SSS four-door sedan with twin side-draft Dellorto 40 mm carburettors and other sport features was developed
In the UK the Datsun 1200 was the first Japanese car to sell in large numbers, being the company’s best seller there when its sales soared from just over 6,000 cars in 1971 to more than 30,000 a year later. The 120Y model, launched there in the autumn of 1973, helped take the brand from strength to strength, as did the smaller Cherry models.
It was well equipped for its price with disc brakes and reclining front seats. This model established Datsun as the top Japanese exporter of cars to the UK.
Coupe total sales: 89,541
Two-door sedan total sales: 43,761
On the 4 April 1971, halfway through the model year, the Sunny Excellent (PB110 series) coupe debuted for the Japanese market. It was based on the B110, but with new hood, fenders and grille, and featured a SOHC 1.4-litre Nissan L engine. The front overhang was extended 130 mm (5.1 in) to accommodate the larger P510 type radiator and the wheelbase by 40 mm (1.6 in). The engine position was retained in the same position as the original A-series engine which further assisted the handling even though the engine was heavier. No changes were necessary to the firewall. The PB110 was offered in both GL (single carburettor) and GX models (twin carburettor). In Mexico this was marketed as the Sentra 1400.
At the Tokyo motor show, 19 October 1972, a Sunny Excellent with Nissan’s two-rotor Wankel rotary engine was exhibited.
