The Datsun Fairlady 1600 SP311/SPL311 was a two-door roadster produced by Datsun (now Nissan) from 1966 to 1969. It marked a significant step forward for the Fairlady line, introducing a new, more powerful engine and a refined, sporty design. The SP311, the first model, boasted a 1.6-liter four-cylinder engine, producing 96 horsepower, a significant leap from its predecessor's 89 horsepower. While the engine was a key improvement, the SP311 also featured a new, more rigid chassis, upgraded suspension, and a stylish new design with a longer wheelbase and more sculpted lines. This combination resulted in a more agile and refined driving experience, making it a popular choice for both enthusiasts and everyday drivers.

The later SPL311 model, introduced in 1968, saw some minor updates aimed at further enhancing performance and handling. These included a slightly revised engine for better fuel efficiency and an improved braking system to handle the increased power. The SPL311 retained the SP311's sleek design and sporting character, making it a desirable classic even today. The Datsun Fairlady 1600 SP311/SPL311 played a crucial role in establishing Datsun's reputation for building affordable, fun-to-drive sports cars. It paved the way for the iconic 240Z, which would later become a global sensation. While not as widely recognized as its successor, the SP311/SPL311 remains a sought-after classic for enthusiasts who appreciate its unique blend of style, performance, and affordability.
