He calls it a J20 vs a 40...but was actually kind of interesting to see the (basic) aerodynamics of our bricks:

What happens when those front vents are opened?

It’s been 16 years since I’ve had to use my brain for anything serious, and 30 years since I was in/around anything to do with CFD and almost 45 years since I got my aero degree, so it’s humbling to see where the world of CFD has progressed to, even if it is to compare the aero of a loaf of bread and a FJ40 . We used to have to run the Navier-Stokes code on a supercompter for hours to get one solution point on those colored contours shown in the video. I guess I’ll just stick with brainlessly driving around my bluff body 40 on dirt roads chasing the cows .

Yeah but I want to know about banana bread…. Toasted with a good amount of butter… Or better yet- banana bread French toast….
Back in my design days I worked up an detachable adjustable wing to fly out in front of the bumper just to improve the aerodynamics of the brick. I did a dc powered turret too because you need two people to "Rat Patrol"
One of my favorite Bill Mauldin's cartoon is a crawler getting ready to pull a B-24 stuck in the mud, The operator yells up to the pilot "No foolen that thing really fly's!"

Seems pretty clear that you just need to strap a loaf of bread on the front bumper, and you're drafting... right?
I bet if I ‘butter up’ my bumper and bib…..it’ll help stream line the rig, I wonder what Computational Fluid Dynamic (CFD) inputs would be required to adjust for a ‘buttered bumper’……just thinkin’ out loud here

I'm surprised the 69 mustang scored so poorly.
I always referred to my 40s as a rolling Bread "BOX".
So, if I load the "box" with with a loaf, will I get better mileage?

Butter normally ends up on the back end rather than up front, and it doesn't usually lead to a streamlined outcome iirc...I bet if I ‘butter up’ my bumper and bib…..it’ll help stream line the rig, I wonder what Computational Fluid Dynamic (CFD) inputs would be required to adjust for a ‘buttered bumper’……just thinkin’ out loud here
