KPGC10Following its release to dealerships around Japan on January 4th 1969, then in May 3rd 1969 it hit the First GTR, the Skyline GTR PGC10 hit the racetracks in the JAF Grand Prix dominating every race it entered until it retired after 1972.
1973 saw the release of the KPGC110, affectionately know and the Kenmeri Skyline GTR. Using the same S20 inline 6 engine. The rarest GTR of them all thanks to the 1970s oil crisis, which also meant the car never saw racing.
In addition the ATTESA E-TS rear wheel drive based all wheel drive system coupled with technologies such as 4 wheel steering (HICAS) made this car a monster on track and on the road to this day. With a planned max horsepower rating of 600ps Nissan engineers worked out to effectly put this power down the power would have to be split between all four wheels so 150hp per wheel.
It was a venerable platform even in it's restricted 280HP production spec and took the then production car record laptime at the Nurburgring Nordschleife of 8 Minutes 22 Seconds https://en.wikipedia.org/wiki/List_of_N%C3%BCrburgring_Nordschleife_lap_times.
Since the BNR32, Nissan conducted extensive testing at the Nurburgring Nordschleife with the standard BCNR33 Shaving 21 seconds off the previous BNR32's time and posting a time of 8 minutes 1 second. However the GTR development team was not happy with this and returned with the Vspec BNR33 and posted a new production record at the time of 7 minutes 59 seconds driven by Dirk Schoysman https://en.wikipedia.org/wiki/List_of_N%C3%BCrburgring_Nordschleife_lap_times.
The RB26 and R34 production ended in 2002 with new emission regulations and to a smaller extent Nissan's pre-Gohsn financial woes.
