The Datsun 510, produced from 1968 to 1973, is a compact car that marked a significant shift in Datsun's (now Nissan) strategy, moving away from purely economical vehicles to more performance-oriented offerings. The 510, internally designated as the PL521, was built upon a new platform that emphasized handling and driver engagement. It was available in a variety of body styles, including a 2-door sedan, 4-door sedan, 2-door coupe, and a 4-door wagon. The 510's sleek design, with its distinct fastback profile and wraparound rear window, was ahead of its time and contributed to its enduring appeal. It was offered with a choice of two engines: a 1.6-liter four-cylinder engine producing 88 horsepower or a more powerful 1.8-liter unit pushing out 96 horsepower. Both were paired with either a four-speed manual or a three-speed automatic transmission. The 510's impressive handling, thanks to its relatively low weight and suspension setup, made it a favorite among enthusiasts, especially with the availability of optional performance upgrades. The Datsun 510's legacy extends beyond its design and performance attributes. It achieved notable success in motorsport, winning numerous races in the SCCA's B-Production class and even capturing the 1970 and 1971 USAC championship. The 510's performance capabilities and affordability contributed to its popularity in rally racing as well. The 510's influence can be seen in later Datsun models, particularly in the development of the successful 240Z sports car. The 510's lasting impact on the automotive world is evident in its enduring popularity among car enthusiasts. Its classic styling, spirited performance, and relative ease of maintenance continue to attract collectors and driving enthusiasts alike, making the Datsun 510 a sought-after classic car.
