From the EM archive (the wind tunnel, smoke thread)

Approximations of Hucho's CD 0.16 “ideal" shape in the wind tunnel (from our thread for wind tunnel images) are below. Also attached are 4 pages from Hucho, 4th edition (pp.45-46, 212-213), which include wind tunnel images (p.212 might be best). They describe such ideal shapes in the R&D process. I would love to hear from aerohead about the benefits he sees to the template shape in comparison to the one Hucho often seems to emphasize, calling it a "basic body." Respectfully, james.





HUCHO, 45-6, 212-3:

See my car's mod & maintenance thread and my electric bicycle's thread for ongoing projects. I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
