Aero trailer increases EV range

There's a presumption that I have ready access to the images.

Those details led me to this, which looks correct.



If adding that feature reduces drag 17%, then I too wonder why it's not implemented.

Either of you could have just looked into aerohead's album:

Gap Encl. (top and sides) Incremental Decrease 19.7% Cumulative Decrease 40.2%

I was focusing solely on the wind-averaged gap-filler contribution of 17%.

From Angus Mackenzie's, January 2023 MOTOR TREND reporting it looks like a GT-Line, single-motor 5, with the CdA of the IONIQ 6, at 55-mph, would be in the 362-mile range neighborhood.
This represents the SUV / Trailer combination, with an aggregate drag coefficient of 0.21.
If you go balls to the wall on aero, with the gap-filled tadpole trailer, you improve it to Cd 0.12, and 448-miles range.
--------------------------------------------------------------------------------------
As it sits, the Shorty costs you 27-miles range. A 8.7% range penalty. Not too shabby compared to losing an additional 128-miles ( 50% ) with a 'traditional' RV trailer.
-------------------------------------------------------------------------------------
To put the ultra-low-drag tadpole rig into perspective:
AeroStealth, charging off-peak, on El Paso Electric's overnight rate of 4.7-cents/ kWh, could drive 410-mles, non-stop, to Monahans Sand Dunes State Park, Texas, for $ 3.23. Opportunity-charge while there, at no additional cost over the regular campsite fee, and return home at zero cost.
A gasoline-powered IONIQ 5, solo, at around 30-mpg, at $ 2.55/gallon ( today's price in Denton, Texas ) would cost $ 69.7 for the same trip.
Having been born in a capitalist nation, when people did arithmetic, and payed attention to the 'bottom line', I struggle to comprehend the 'push-back' against BEVs, and the argument that 'they can't tow.'
If anything, they've only cast light upon the fact that RV trailers, with the exception of one, have all been mediocre at best.
I'm very pleased that a conversation might spread around the RV world.

1935 Bowlus Road Chief, right?

BINGO!
