A new article about the Gravity Dream Edition throws a couple of my assumptions into doubt.
I had assumed the 440+ miles of range meant the Dream Edition might slightly exceed this number and that the other versions would fall somewhat short. I had also assumed that the 800+ horsepower and <3.5 0-60 times meant that it would be the Dream Edition that might slightly exceed those figures. Or, in the alternative, maybe the Gravity Dream was going to be more about luxury/convenience features with little powertrain differences from the other versions.
Yet the following article, in which Peter Rawlinson is quoted (without saying when and to whom he said these things), suggests a Dream Edition more in line with what happened with the Air: a limited production run with power and acceleration well beyond the rest of the range (outside the Sapphire, of course).
