Keep in mind, the xB was the brainchild of Toyota Japan, brought to America. Some say the xB is like a minivan, some maybe an SUV. For some reason, I'd still want to see a truck conversion of it like "Haulin' Harry's" Custom Toyota Bb in Tokyo Xtreme Racer Zero. Maybe not a mid-engined example like the one in the game, but an all-wheel drive model of it (not many Americans would like a front-drive truck, or are there any good ones?).
As I say, it's mostly a concept. Not to rant, but the most common mistake many of us make is that we quickly note a Concept Car as ugly. That's not the point. The point of it is to show off something that may be the future of a machine, or just simply build a machine that shows off the creator's dreams (for example, a Honda/Acura NSX with a jet motor). It's likely we won't see this imbreed on the streets, but my guess on what it COULD be is perhaps (I will use "xD" to denote a potential new Scion) a forthcoming Scion that features the elegance of a Scion tC, but with the versatility of the xB. Perhaps a new engine will be given to this "xD." The interior may feature something as versatile and stylish as the dashboard, and maybe a racing-style steering wheel. I think you have to "decipher" a concept car to know what exactly the auto maker has in mind for the future. Usually the concept is a marker for newer styling of cars. A big example is the Cadillac Cien. I am SO not a big Cadillac fan, but look at the styling of the Cien. Did you see any newer Cadillac cars carry the sort of styling the Cien did? Of course!
So while the concept may be bizarre and outlandish, it's pretty unlikely this Scion will hit the streets. Kind of envision what Scion could have in mind as this may look more like a new idea from the Scion camp. In fact, this may be an idea for (don't laugh at me, but...) a station wagon version of the Scion tC.
