Perhaps you should ask owners, many of whom I have heard state exactly that. It's big, comfortable, fast, quiet, clean, futuristic, high status, low maitenece and beautiful machine. Not hard to see its appeal.
It's much faster than other cars in its class. It has supercar worthy acceleration and handling (thanks to that low battery pack it hugs the ground like you have wings).
It's not a sports car, luxury cars pride themselves on what you can't hear.
Well, the best performing option does have excellent acceleration (4.4s to 60) - but they aren't actually that fast in terms of top speed - 130mph. Of course, that is pretty irrelevant to most of us who don't have unrestricted Autobahns to drive on.
