Datsun 1600 Roadster SPL311

The Datsun 1600 Roadster (SPL311), produced from 1965 to 1970, represented Nissan (Datsun) competitive response to British sports cars like the MG MGB and Austin-Healey Sprite. Known as the Fairlady in Japan and Datsun Sports in export markets, the 1600 featured a 1,595cc (97.3 cu in) R16 inline-four OHV engine producing 96 hp at 5,600 rpm and 103 lb-ft at 4,000 rpm through twin SU carburetors, achieving approximately 105 mph top speed. The most significant updates included front disc brakes replacing four-wheel drums and deletion of the previous third seat for improved two-passenger comfort. Riding on an 89.8-inch wheelbase with overall length of 155.7 inches and width of 58.9 inches on 5.60x14 tires, the roadster offered nimble handling and light weight.

Early in 1968, safety legislation prompted updates including toggle switches, padded dashboard and steering wheel center, flush-fit lifting door handles, and a taller windshield with top-mounted internal rearview mirror. The 4-speed manual transmission provided engaging driving dynamics, while the open roadster design delivered classic British-style motoring with Japanese reliability. During its production run, 31,665 Mark II Sprites were manufactured (note: this appears to reference production context). The Datsun 1600 Roadster established Nissan credentials in the affordable sports car market, offering MG-like driving pleasure with superior reliability, paving the way for the legendary Z-car series that would follow and demonstrating Japanese capability to compete in traditional European sports car segments.
