Description
The Datsun Fairlady 1500 SP310, introduced in 1962, marked a major turning point in Nissan’s development of sports cars. It was the first of the Fairlady roadsters to feature a steel body, more refined mechanicals, and styling that aligned closely with the expectations of export markets, particularly the United States. The SP310 laid the groundwork for the success of later models like the Datsun 1600 and 2000, and it began the Fairlady’s true identity as a lightweight, affordable, and capable roadster.
Under the hood, the SP310 was powered by a 1.5-litre inline-four engine known as the G15, derived from Nissan’s earlier E-series engine. This engine featured a single carburetor and produced around 77 horsepower, which was a noticeable improvement over the earlier fiberglass-bodied SP212 and SPL213 models. It was paired with a four-speed manual transmission, with synchromesh on the top three gears. The car’s power and gearing gave it respectable performance for a lightweight roadster of the early 1960s.
One of the more unique elements of the early SP310 models was their three-seat layout. The early cars featured a small sideways-facing third seat mounted behind the front passenger seat, squeezed into the limited cabin space. This feature was short-lived and eventually dropped in later versions to make room for a more conventional two-seat layout with increased legroom and storage.
The body of the SP310 was made from steel and featured clean, classical lines that were heavily influenced by British sports cars such as the MG A and Triumph TR3. It had a low profile, a long hood, and modest tailfins that were a holdover from earlier styling trends. A mesh grille, simple chrome bumpers, and steel wheels with hubcaps contributed to its understated yet sporty appearance. The removable soft-top roof and side curtains offered basic weather protection.
Inside, the SP310’s dashboard was practical and functional, with round analog gauges, toggle switches, and basic trim. The seats were upholstered in vinyl, and while comfort was minimal, the car emphasized lightness and driver engagement. Optional features included a push-button AM radio and a heater, depending on the market.
The suspension system was fairly advanced for a car of its class. It used independent front suspension with coil springs and wishbones, and a live rear axle with leaf springs. Braking was provided by front disc brakes—a significant feature for the time—and rear drums. This gave the SP310 better handling and stopping power compared to many of its contemporaries.
The Datsun Fairlady 1500 SP310 found a strong market in North America, where it was sold simply as the Datsun 1500. It appealed to drivers who wanted a sporty, open-top car with Japanese reliability and a lower cost than British or Italian equivalents. The SP310 began to establish Nissan’s image as a serious player in the affordable sports car category.
Production of the SP310 continued until 1965, when it was replaced by the more powerful Datsun 1600 (SP311). Though often overshadowed by its successors, the SP310 is significant as the first mass-produced, export-focused Fairlady roadster, and it played a key role in Nissan’s expansion into overseas markets.
Today, the Datsun Fairlady 1500 SP310 is appreciated by collectors for its vintage charm, historical importance, and relatively simple mechanicals. Surviving examples are sought after for restoration and classic driving events, especially as part of the broader legacy of Datsun’s early sports cars.
