Aerodynamic improvements are essential for improving fuel economy. Toyota and Honda have recognized this fact and among the highest priorities in designing their new hybrid models, aerodynamics were on the top. Below there is a text translated directly from Japanese that comments on the aerodynamic performance of the new Toyota Prius and Lexus HS 250h.
"Two new hybrid vehicles announced by Toyota and Lexus. Both of common thorough, aerodynamic measures are given.
The Cd value of Toyota new 'Prius' that gives measures even to the disorder of air in the tire house is 0.25 in the top-level world. On the other hand, the Cd value of Lexus 'HS250h' is 0.27. Bahiroyuki of old of the Lexus central product project chief examiner who took charge of development is equipped normally and aero parts "It is actually effective" is equipped normally in the North America specification that the high-speed cruise fuel cost becomes important (A Japanese specification is an option treatment).
Such two was discovered and when it peeped into the lower side of the body from the back of the body, the interesting one was discovered. The rectification fin to straighten the flow of air very much was installed in the diffuser on the other side of the back of the body though it was natural to make the lower side flat. Thoroughness and aerodynamic measures are like the racing machine."
