An Illustrated History Of Automotive Aerodynamics – In Three Parts

[Note: A significantly expanded and updated version of this article can be found here]

That air presented the greatest obstacle to automotive speed and economy was understood intuitively, if not scientifically since the dawn of the automobile. Putting it into practice was quite another story. Engineers, racers and entrepreneurs were lured by the potential for the profound gains aerodynamics offered. The efforts to do so yielded some of the more remarkable cars ever made, even if they challenged the aesthetic assumptions of their times. We’ve finally arrived at the place where a highly aerodynamic car like the Prius is mainstream. But getting there was not without turbulence.

  • 3-On-The-Tree Besides for the sake of emissions I don’t understand why the OEM’s went with small displacement twin turbo engines in heavy trucks. Like you guys stated above there really isn’t a MPG advantage. Plus that engine is under stress pulling that truck around then you hit it with turbos, more rpm’s , air, fuel, heat. My F-150 Ecoboost 3.5 went through one turbo replacement and the other was leaking. l’ll stick with my 2021 V8 Tundra.

Anyone with half a brain recognizes that Tesla is slowly settling in to becoming just another EV manufacturer, now that the legacy manufacturers have gained a sense of reality and quit tripping over their own feet in converting their product lines. Who is stupid enough to believe that Tesla is going to remain 90% of the EV market for the next ten years?Or is it just cheap headlines to highlight another Tesla "problem"?
