Since 1957 the Skyline sedan had been around but the GT-R made its debut at the Tokyo Auto Show in the fall of 1968 and was introduced in February 1969. The beast’s beating heart was the 2.0-liter dual-overhead cam S20 inline 6-cylinder engine that produced 160 horsepower and 130 pound-feet torque. The first-generation GT-R was officially known as code KPGC10 and bore the acronym “Hakosuka,” which was a variation of the Japanese terms for box and skyline. The car with a 104-inch wheelbase was 173 inches long and weighed 2,469 pounds. It could take 16.1 seconds to cover the quarter-mile and reach a top speed of 124 mph. It could corner, too, as it proved by winning the JAF Grand Prix in its debut race. The car became available as a coupe in 1971. All told, 1,945 of the first-generation cars were produced.
