Many changes were made in 1965. Though the 1.5 L SP310 continued in production through January, a new 1.6 L R16-powered SP311and SPL311 (left-hand drive) replaced it. The new model was first shown at the 1964 Tokyo Motor Show, but did not enter production until March 1965. The restyling was executed in part by Count Albrecht Goertz, who would later be involved with designing the first Fairlady Z.[8] Marketed as the Fairlady 1600, or the Datsun Sports 1600 in many export markets including North America, it featured 14 inch wheels and minor exterior changes.[8]The SPL311 was also known as the "Roadster" on the West Coast of the United States. The front suspension was independent, using coil springs over hydraulic shocks. Rear suspension was a common leaf springs design, damped with hydraulic shocks. The 1600 SPL311 came with a pair of SU carburettors. The engine produced 96 PS (71 kW; 95 hp).
