The first true Datsun sports car was the 1963 SP310 "Fairlady 1500" model (right hand drive), and the SPL310 (left hand drive). In America it was known as the Datsun 1500. The SP310 was based on a modified Bluebird 310 sedan platform instead of the truck platform of earlier models.
It featured an 85 hp 1.5 L (1,497 cc) G15 engine (from the Cedric) but with a single SU carburettor. Only 300 SPL310's were equipped with the single carb and these first few had only 77 HP as opposed to the 85 HP of the dual carb models built in 1964 and 1965.
A four-speed manual transmission was the only shifting option and has a non-syncro'd first gear. The rear axle used the shafts and differential also from the Cedric. It was a well-equipped car with a transistor radio, tonneau cover, map lights, and a clock. The first SP310s (1963–1964) also had a unique sideways third seat in the rear.
