I'm back from 5 day camping trip towing 17' Casita Freedom Deluxe Travel Trailer (3200 lbs weight)

[65SoYoLO]

So is this showing the drive time (~45Mph for 102 @ 2:24) or does that include the charging stop(s)?

I am not sure. We did hit a little traffic the GWB and the cross bronx.

I was also only going 30-45 for 15 miles and then 55-65 mph for the rest of the trip depending on traffic and road conditions....

↑ This is the not-so-secret method to get better efficiency in all situations, empty/heavy/light/towing/not-towing: drive slower.

Aerodynamic drag is the main factor affecting efficiency for our trucks, and the drag increases exponentially, a function of the speed squared (v²). Increase your speed 5%, say from 60 to 63 mph, and the truck expends about 10% more energy to overcome aero drag. Increase your speed 10% more than 60, to 66 mpg, and the aero drag increases 21%. A 20% increase in speed, from 60 to 72 mpg, increases aero drag 44%.

The mathematical part of my brain tells me to drive 60 even through I'm being passed by a truck hauling a landscape crew and trailer, but my emotional brain makes me press - hard - on the go pedal and forget the numbers....

Argh! I only have one of me hogging all he charging spots (NO ONE tried to charge) but maybe my woman has more.

Your Woman has MORE! Let's see what see has to say 'bout D'@?!?!?!?

Nope, no more pictures.

Nope, no more pictures.

That's a SHAME!
BTW Do you believe the 'current' pic of CYBERCAB could be hiding a 3 Wheeler Car or at worst a narrow track tight rear end with two wheels inboard of a fully faired rear bodywork? Just asking for a friend who reckons it's highly possible!

not with this trailer since it is very light, I had them set at 55. I also tow an 8000lbs trailer and i increase the pressure to 60. It felt very squirrely.

I will be towing a trailer with 3-quads on it. Probably a total 2500lbs including the trailer. What mode?

 

[65SoYoLO]

any mode you like. I stay in custom mode, low and slow for economy but you can tow in any mode.

Curious if regen braking works well when towing or do you need to combine with pedal brakes when going down a mountain, or freeway exuts, etc.? Nice post

Yes, regen works.
And at certain levels of regen, the vehicle puts it brake lights on. And that's probably the indication for a little trailer braking as well.

LOL thanks for making me revisit Aerodynamics For Naval Aviators

You must use the following equation to calculate the parasite drag DP = ½ ρ V2 C,0 A. This equation uses ρ = air density, V = velocity (airspeed), C,0 = zero-lift drag coefficient, and A = surface area.

Yes, parasite drag varies directly with velocity squared (V 2 ), so a doubling of speed will result in four times as much parasite drag.

I suspect you had to have that formula thoroughly memorized, so you didn't have to look it up while landing on a carrier, in a storm, at night....

I had an US Air Force chaplain describe that experience when he explained why he had a US Naval Aviator badge on his USAF uniform.
