Looking at the design, the first thing that occurred to me is that it looks like the frontal surface area would be increased compared to a traditional commercial jet with the same wingspan, which I would expect to negatively impact fuel efficiency. I did a bit more thinking and some reading to try to determine why this isn't the case.
For one thing, while the split fuselage in the images appears similar to that of a conventional airliner, I expect it would actually be considerably shorter than that of a jet with comparable capacity, the reason being that much of the luggage and equipment that would normally be stowed below the passenger compartment could instead be relocated to the center of the 'v'.
You would still have somewhat more frontal surface though I would think. Perhaps this could be outweighed (no pun intended) by weight savings and lower surface area. Although I wonder if some of the savings would have to come from flying more slowly, which this design might facilitate.
I don't know anything much about aeronautics though, so would love input from someone who does!
