Pickup truck aerodynamics

[aerohead]

I'm scattered between a number of threads.I only managed to get a couple of new images posted here at the top of the thread.
I did get to do some photo-enlargements to work on for next week.

This showed up,when GOOGLING for RAM pickups:

You notice the K-Form greenhouse.
This will be a door into the 2025 CAFE standards.Consumers will decide its fate.
We're finally getting back to 1913,when pickups were based on passenger car 'styling.' I like it very much.

I'll start a list for p'up drag coefficients and we can add and update as new data becomes available.The Cds will be in descending order, from high to low

Your link is broken for me. I believe this is what you were linking to. The 2016 Dodge Dakota pickup truck

And the GMC Centaur reminds me of a Toyota Previa with a truck bed, cool!

I'm still quite the neophyte when it comes to links (and a thousand other things!)
Appreciate the backup.

The full statement is always "Your link is broken in this browser at this location/time." It works for me.

aerohead -- You still have the Ghia, right? Convert to electric and then build a box from behind the seats to 6" beyond the stock back bumper. Presto, fodder for the link.

I landed on Permalink #41 and revisited the Original Post.

Do you have an actual DBA? Are you actively using this title currently? I used to brand my Christmas cards with 'Bougas Enterprises'.
