The fourth-generation Skyline appeared in 1972. Due to the effects of exhaust gas regulations and the oil crisis, there were no major improvements in performance from the previous generation, but the sophisticated design that made extensive use of curved surfaces and the commercial strategy featuring KEN & MARY, a male and female couple, as new image characters were successful, making it the biggest hit in Skyline history.
The 4th generation Skyline of such a soft line, commonly known as Kenmeri, is a GT-R grade KPGC4, which boasted unbeatable strength of racing cars based on the same car, has been manufactured for less than a year.
Just under 110 units of the KPGC1 were produced. The K of KPGC stands for 200 doors, P means that it is equipped with an S110 engine directly related to Prince, and GC2 means the model of the 20th generation Skyline. There are other theories about the reason for the extremely low production volume, such as to sweep away excess inventory of engines that had been prepared for the GT-R (KPGC110) based on the third-generation Skyline, but since Nissan never raced in earnest with the KPGC4, it is reasonable to assume that it was part of the image strategy of the fourth-generation Skyline.
Currently, due to its small production volume, it boasts overwhelming popularity as a coveted collector's car among successive GT-Rs.
