Concept is a cool idea, 80mpg enclosed trike for under 7k$ that comes with AC and a stereo? I don't believe the mpg figure, as all manufacturers tend to pad the results. I used to ride a Kawasaki 650R, supposedly was good for 50mpg but never saw anything above 35mpg(-1/+2, slip on, pcIII). The Elio doesn't look very good imo, but if it ends up at getting 70+mpg while still having a 0-60 under 10sec it would be an amazing commuter...
