The interior design of this car is just beautiful. I particularly like the idea of sitting in and telling the car to speed it up. ETA's will just disappear to moments. The exterior is certainly futuristic and has nods to the SLS front end but I'm not sure if I like it. It looks robotic which I assume was part of the brief.
However, I still think the Lexus 2054 EV from Minority Report has a great look and that was designed in 2002 for the movie.
But the most desirable car of the future has to be the BMW i8 . The crazy thing is the future is already here and that model is currently available, albeit with a decent waiting list. Keep your robot Merc I'll take the beamer and drive myself.
