The article lists some reasons:^ wow...that’s a significant delay...wonder what happened.
Never would have thought the GV80 would be first!!
1.) North American sales are down in terms of sedans, Genesis needs to prioritise their first SUV.
2.) The facelifted Hyundai Grandeur is being released in September. Hyundai don't want the new G80 to canniblise its sales, as some may be converting to the G80.
3.) There may be changes being made to any aspect of the car, that need sorting.
