If that was about the Greenbrier, cooling system drag is substituted by fan power. No Mustang (car or plane) ram air for cooling.
Maybe, comparing the road load of the Greenbriar, to that of a Ford Econoline, at Cd 0.50 and its CdA, we'd compare added cooling fan horsepower, compared to the horsepower reduction accomplished with the lower drag, and look at the differential.
On a frontal area basis, the lower Cd means lower power, lower heat flux, reduced cooling load.
The Corvair is starting out with 24% less drag.
As to the P-51 Mustang, remember, we're talking about transonic/ compressible flow, something unachievable in a road vehicle at posted legal speeds.

Agreed that any cooling fan power should be factored into overall drag. However, the Mustang only encountered compressibility in a dive, and cruised with the bombers. Adjustable cooling vents seem to be almost universal on ICE aircraft.

I always liked the radial vents on a radial engine. For whatever reason.

If you're ever near Chino Airport in California, check out their Planes of Fame flying museum and Russian YAK-3 aircraft.It has an exquisite set of vane shutters in front of its radial engine.

Do they twist or slide?

Isn't it nice they included a white arrow pointing to the exit?

They twist and are not used for cooling but keeping it warm

Canoo

Jay Leno did a show on the company and car. Inside Look At New Car Company Canoo - Jay Leno’s Garage

What I notice is the continuous chamfer along the upper edge. Much like the Cybertruck nose. It seems to be a design language that extends through the truck proposal. The window sections above the doors flip open.

Also the the jump seat on a suicide door.

Thanks for the clarification. We were headed to lunch and I only saw it from a moving vehicle, so I can't say. They did remind me of the inlet vanes of some centrifugal blowers, as Texas Tech used on its scale wind tunnel air mover.

I'm a fan of Nakai-san.



Not so much a fan of Donut Media's production values (although it is available at up to 2160p!). I watched with my right middle finger on the right arrow key.

Anyways, RWB is in the same league as the Emory family and Magnus Walker. The wide-body style is not EcoModder-friendly, but the fit and finish is flawless and I learned some things:
The Beetle wide-body isn't really much wider, it's more about trading the stock radiused opening for a knife-edged one. It has an early-911 spoiler, but the Hoonigan car has me thinking about a Herrod Helper with curves strakes on the bottom to feed air to the intake.

https://www.carscoops.com/2017/02/ja...ts-innovative/

I find this interesting for a number of reasons:
  • Zepplin-era on top, 21st century on the bottom
  • Gull-wing top is lift-off
  • Catherham-style nose but it's mid-engined
  • Open front fenders have a winglet behind the front wheel
  • Lower rear scoop wraps behind the seats
  • Upper rear scoop swallows the front fenderline
  • Horizontal side skirts
  • Reverse rolled pan above the diffuser
  • Sail panels terminate in strakes
Am I missing anything?
