The first cars named "Skyline GT-R" were produced between 1969 and 1972 under the model code KPGC10, and were successful in Japanese touring car racing events. This model was followed by a brief production run of second-generation cars, under model code KPGC110, in 1973.

The Nissan Skyline is a brand of automobile originally produced by the Prince Motor Company starting in 1957, and then by Nissan after the two companies merged in 1967. After the merger, the Skyline and its larger counterpart, the Nissan Gloria, were sold in Japan at dealership sales channels called Nissan Prince Shop.
