Oh, it's got two fuselages and 4 wheels too... would you expect anything less unusual from Burt Rutan with his last design project before he retired from Scaled Composites April 2011? If you know anything about the amazing and unique career of Burt, you know this is right down the middle for him!
According to this Aviation Week article, the BiPod first flew on March 30th, but those were just 'hops' into the air via the driven rear wheels. I'm not sure the current status of flight testing or of the propeller installations. I'm sure more info will surface before long.

The Scaled Model 367 is unconventional on many levels. It's a roadable electric-hybrid aircraft for two people with an intended high speed cruise of 200 mph. It'll have two 450cc engines (one in each fuselage) powering generators designed to drive two 15kW motors at the rear wheels for 'road mode', and then four 15kW motors spinning props for flight mode. As the illustration below shows, two of those motors are mounted on the wings outboard of the fuselages, and the other two are mounted on the horizontal stab between the fuselages. There are also some small batteries in the nose to provide a little power boost when needed, and also to act as a short duration backup in the event of a total loss of engine power.
