Quite a common oversight amongst those watching, but the R31 was never a GT-R, but a GTS-R. However, it's that Skyline that gave the likes of the R32 and onwards the technology they had, such as a HICAS system.
@@Mefdash there is no R30, which was never a GT-R nor a GTS-R, but an RS-TURBO in its highest trim level, which ultimately never made it to Forza, except from Motorsport 7 as a Group 4 Silhouette racer. Unless you're referring to the R31 GTS-R and confused it with the R30, you're correct; it's not in this video for the sole purpose that it's strictly GT-R's they're comparing.
