The first Skyline GT-R, known by the internal Nissan designation of PGC10, was introduced on 4 February 1969, and was exclusive to Japanese Nissan dealership network called Nissan Prince Store when the Prince company was integrated into Nissan operations in 1966. It was available originally as a four-door sedan after a public debut at the October 1968 Tokyo Motor Show. It was advertised alongside the Nissan R380 racecar to showcase the Skyline's racing heraldry. It was equipped with the 2.0 L DOHC S20 Inline-six engine rated at 119 kW (162 PS; 160 hp) at 7,000 rpm and 176 N⋅m (130 lb⋅ft) at 5,600 rpm. Power was delivered to the rear wheels by a 5-speed manual transmission and the car was equipped with a limited slip differential. The first Skyline GT-R rode on a semi-trailing arm strut suspension. The braking system consisted of disc brakes at the front and drum brakes at the rear. It was available in a coupé bodystyle in March 1971 with the chassis code KPGC10.
 
The interior of the car was very basic and featured racing bucket seats and a three-spoke steering wheel along with wood inserts. The pedals were finished in aluminium.
A popular name for the PGC and KPGC10 Skyline GT-R was "Hakosuka," which combines the Japanese word for box ("hako" or ハコ) and the pronounced abbreviation of skyline ("Suka" or スカ as in スカイライン or "sukairain").
 
A total of 1,945 PGC and KPGC10 Skyline GT-Rs were produced.
