It fits into a niche that few would have thought even existed - between the 3-series sedan, whose wheelbase it shares, and the ungainly 3 Series Gran Turismo with its tall roof and longer wheelbase. The 4 Series Gran Coupe has a bit more cargo room than in the 4 Series sedan
Even bimmerpost is confused by this car.
Whyyyyy didn't BMW make this into a true 4-series Gran Coupe, without the hatch? If they really wanted to make this car, just call it the 4-series Gran Turismo and be done with it. Now we're never going to get a true baby 6GC.
