Engineering Explained:Why Tesla's Are Bad at Towing

[freebeard]

Thank you for your support.

I've already provided links to all the information I've used on page one.Anyone interested will do the research.And do the math.There's no substitute for self-discovery punctuation. [count the spaces]

I'd be made happy with a summary in the new post of the addition to the Dr. Bronner All One-God-Faith style wall of text in Permalink #1.

Is there a post with a picture of a Showstar? If you do an image search you might want to have Safe Search: On.

F the safe search I want to see some weird shht.

Also this is not a Tesla thread. It's about towing with an EV so a Rivian thread if anything as they will be the first to market with a capable EV tow rig.

Yep first fleet only to market, whatever good that does

Bet you that the consumer R1T is in customer hands before we even know the real truth of what a Cybertruck has. I bet 18 months ahead of the first customer delivery of a Cybertruck. I also bet 4wd vs 4wd they are also the same price after tax incentives.

Really? Seriously?

Perhaps you could get the OP, aerohead, to get the mods to change the title to reflect your personal interpretation.

"First to market" is a forward-looking statement.

First to market isn't necessarily an advantage. Myspace was there before Facebook, the Chevy Bolt came out before the Tesla Model 3...

I expect the CT will outsell the Rivian.

...sorted by sentences. If you sort by paragraphs it returns this:

•Since all I want is some mental image of what you're on about I go duckduckgo.com/?q=trailer+dome+ecomodder&iar=images and six of the returns are things I've posted.* (Try it) Since it's a subject obviously of interest to me I hope you can see why I use my words to prompt for a frame for the wall o' text at Permalink #1.

* Still the ultimate tiny house:

At 15-weeks now,I've yet to complete all the calculations and drawings for the TFLcars.com rebuttal AeroStealth is going to do on YouTube.With help,it's my intention to publish them here.
Ultimately,the aerodynamics will digress all the way back to the Lillianthal Brother's,Eiffel,Maurice Farman,Frederick Lanchester,of the 19th -Century.Paul Jaray to the present.
Online,'Fairing Well',from NASA,has a recipe for truck aerodynamics that all contemporary trucking companies use worldwide.Freightliner Corporation came up with the same stuff.General Motors presented very similar results in 1963.Ford Motor Company displayed similar technology at the Seattle World's Fair.AeroVironment/General Motors set a very high bar for aerodynamics in 1987,with Sunraycer,of which GoroTamai elaborates on in his book,'The Leading Edge.'
None of it's made it into the RV industry.
At the Tesla owner's forum online there are testimonials about member experiences towing RV Travel Trailers with the Model X.
Using the recipes published 40-years ago,for instance,anyone can take a Bowlus-Teller Road Chief,and streamline it such that in California,a Tesla ModelX can tow one with 316-miles range,away from the mountains.Tow over to Leo Cabrillo State Park for a couple weeks of Pacific Ocean recreation for instance.
Cybertruck,solo,will consume 273 Wh/mi compared to 216 Wh/mi for the Model X,with 426-miles range.Pulling the streamlined Bowlus nets 632-miles range in Cybertruck.This addresses the 'relativity' of TFL's and Jason Fenske's conclusions about BEV towing.
Road horsepower more than doubles between 55 mph and 71 mph.Towing at 75 mph needs to be seen in its proper context.You may have noticed that,there's not a commercial trucking company that attempts to pull an 88,000-pound rig up a 7% grade at 75-mph.And it's germane to Andre's attitude towards zero-concession towing.The RAM pickup,pulling the Cimarron ShowStar returned 26.5 miles range with the Model X fuel tank.The Model X could do it at 45-miles range.
We hope to clear up this contextual confusion.More work to do.

I can understand you want to keep all your stuff in a single place but then the progression of the tread doesn't make as much sense as new info is added out of sequence basically.

There's been so much banter going on in this thread, which has nothing to do with engineering, that I don't dare place anything,anywhere other than page-1.It'll just get buried in an avalanche of minutia.A lot of you guys appear to completely miss some of the data anyway,and ramble on in an information void.I don't have time to rectify the situation.

A 3D printed part would be sintered. A mold taken from a 3D printed pattern would be cast. Maybe 3D print wax and bury it in sand?

Sintered cast or forged, further options would be cryogenic tempering (changes the grain pattern and shrinks the part some %) or surface treatment (irradiation or whatever, anything but pink/magenta powder coat )

Decades ago,about four universities,working together,were able to model a closed,a cubic-octet 'foam',which achieved the theoretical upper boundary for elastic strength in all modulii.With laser-sintered metal 3-D printing they can be manufactured.I believe the Volkswagen Bugatti successor to the Veyron features a component of sintered-metal 'bird-bone',based upon this theoretical work.It will be 'transformative.' Extremely interesting!
