Tesla model 3 trailer

Is it not possible that, if well designed, the trailer might increase the aerodynamics, at least when empty?

Torklift is the best, but they only build them one way, and that is HEAVY, though this M3 hitch has far less material than was needed to mount the i-MiEV. I drilled 10 lbs out of my i-MiEV hitch and then subjected it to heavier duty than most sane individuals would consider for such a car. No problems.

Thanks. Only issue for me would be reduced clearance in back. My driveway has a dip and high spot that I barely clear now. Maybe I should rent a concrete grinder.

It won't be until 2020,but the plan for DARKO is to simulate a 1-wheel trailer behind Spirit.
The research done by Jaray,Lay,Kamm,Fachsenfeld,etc. all imply that a 'trailer' could complete the ideal fineness ratio of a fully-boat-tailed vehicle.

Sure thing Jim, but you’ll only lose clearance when towing. The receiver tube disconnects from the frame when not in use, which makes it invisible and lighter too.

Here is what I have come up with.

I found this used trailer. It is 8 feet by 52" so its perfect for moving 4x8 sheets. It has 15" rims with real highway rated (75 mph) tires on it. It is also fairly light. I can move it easily by hand on flat ground. The only drawback is that it is fairly high. I bought a 10 foot boat and the plan is to transport the boat like this, upside down. I will enclose the sides of the trailer to make it weather resistant and more aerodynamic, and I want to build a fairing on the front of the trailer to direct the air around it.

This is just a mock up with the straps holding it in place, I will figure out some way to mount it from the inside.

Its probably more aerodynamic with the boat turned around.

Normally, I'd agree; it's the conventional wisdom.

But looking at the attachment, I see an opportunity to add a V-shaped shield on top of the hitch. Or maybe blades, as in Vortex Trap below:



There's probably some taper in the hull anyway.

I got my hitch installed. Heres what it looks like so far.

Having the top of the trailer open will kill the range. Might get better range by turning the boat around the other way. It would be worth testing.
