These models appeared with Datsun 120Y, 130Y", "140Y and 150Y badges in some markets (reflecting the engine size) though Sunny was increasingly used for export, too. The North American version was marketed as the Datsun 210. The B310 was known for its high equipment levels and build quality at the time. It was available with the same A-series engines as its predecessor although the B210's optional 63-series five-speed transmission was replaced with the more compact and lighter 60-series unit, with a standard gear pattern. On all body variants except the Van and "squareback" wagon, the leaf spring rear suspension was replaced by a more advanced coil spring four-link configuration, while the front had struts with coilover springs. Other than that, the chassis was very similar to that of the B210, albeit with a beefier front suspension and a relocated fuel tank in the sedans. It was now beneath the floor of the trunk, freeing up more space for luggage. The body was designed to provide fewer moisture traps, helping protect the car against rust, while added width meant additional space, particularly for the rear seat passengers.
