The Urbee is space-age car that is manufactured via 3D printer. It’s so highly fuel efficient that the makers are about to see if the second iteration of the auto can drive cross country on just ten gallons of gasoline. I would guess someday most cars will be manufactured this way, though they’ll be a market for “hand-crafted” cars the way there are for shoes and such. From Michael Kwan at Mobilemag:

“Even though we’ll keep getting talk about hydrogen fuel cells and fully electric vehicles, there is still a lot more to be said about just getting more fuel efficient vehicles at all. And this could be one of the craziest extensions of that philosophy to date.

For starters, the Urbee 2 is a car that was built using 3D printing, rather than more conventional manufacturing methods. They aim to drive the car clear across the United States on just ten gallons of fuel. To put this in perspective, the first Urbee was already able to achieve over 200mpg on the highway.”
