the 4wd system weighs alot (biggest hurdle) and if a car is balanced properly in terms of power and weight and chassis its better off being fr layout to b a competitive and renowned sporst car.
fr layout= no gtr but they can adapt a 4wd systme to weigh close to nothing as they have done in a nissan hatchback(cant think of name in japan car market recently)
id like to see it represent japan and be unique rather than to try and compete on a new level to try and sustain gtr emblem.
