This Cd was achieved with a cross-section that looks like an airfoil, an enclosed floor, flush-mounted windows, and its elongated roof.
The Goettingen Egg (Göttinger Ei) is compared to an
Egg of Columbus - Wikipedia, the free encyclopedia , and it's suggested that modern aerodynamics researchers could stand to learn from the Ei. If Schloer has achieved Cd=0.15, then so can they.
They also mentioned that they had the model in a modern wind tunnel in Göttingen with laser smoke visualization, hence the goofy sound effects around 1:58.
