A Brief Illustrated History Of Automotive Aerodynamics – Part1

Hello -

Here's an article I am sure you will enjoy :

A Brief Illustrated History Of Automotive Aerodynamics – Part1 | The Truth About Cars

Quote:
The T77 was measured to have a Cd of .212, a number that was not broken by a production car until GM’s EV-1 of 1995, which measured at .195. A remarkable achievement, the long-tailed T77 was powered by a rear air-cooled V8, and began a long series of Tatras until the 1980’s along similar lines.

You know you're an EcoModder when you read this line from the article's intro....

We’ve finally arrived at the place where a highly aerodynamic car like the Prius is mainstream.
...and you fundamentally disagree with the notion that the Prius is "highly aerodynamic."

I don't have the source with me ( I'll get it ),but the Tatra was re-tested in a modern full-scale wind tunnel and it's Cd did not approach the published Cd,and by a large margin.

Yes, thanks, I remember that too. That was posted long time ago in a thread far far away ... I'll quote it if I find it.

Thanks, cfg83; I read it yesterday before leaving work. I didn't bother to check back here because I knew it had been out for a bit (I have TTAC on RSS) and figured someone will have posted it.
