New aero tubing profile

A bike company gas developed a new tube profile with better aerodynamics than an airfoil with 5 times the length. Trek has used a classic Kamm pictured 2nd from the right in the gray photo but the new ovoid shape on the far right would seem to have the much better cd of an impractically long complete airfoil.
