Oh, I am not so surprised. Edmund Rumpler had a Ph.D. in aeronautical engineering and clearly thought a great deal about drag reduction. He was also a prolific designer, whose most famous product was the Taube of WW1 fame.

And this was his 1926 design submission for a transatlantic passenger plane.

Low-drag designing certainly did not end with him, though. In 1980 the Volkswagen ARVW registered a 0.15 Cd and went on to set numerous world speed records for diesels, ultimately setting the still-existing closed course diesel record of 362 kph (225 mph). It also got 39 mpg at 250 kph (155 mph) and 18 mpg at top speed!

Best tank ever: 72.1 mpg in February 2005, Seattle to S.F.
New personnal best 'all-city' tank June '08 ... 61.9 mpg!
Thanks to 'pulse-n-glide' technique.
