Wish I knew the specs (CDA, etc etc).

FYI wikipedia entry: Rutan VariEze - Wikipedia, the free encyclopedia

puts it at 35mpg at 181 mph in "stock" form.
That's essentially how all commercial scheduled flights operate. They accelerate (pulse) to 30,000 ft cruising altitude where the air is thin and resistance is low. Then they semi-glide back down.

From my experience in smaller propeller planes, they do operate at best BSFC all the time after takeoff is completed.
