DATA THREAD: Post your tow and efficiency!

[TomB985]

This is great, keep ‘em coming! I’ll assemble this into a Google Sheet and append to the OP in the next couple of days.

I put the posted information together in a Google Sheet that I’m adding to the OP. Let me know if there are any corrections, and I hope we get more input from others who tow.

I just looked up the TimberLeaf Pika's Off-Road model height, and it's 72 inches... but it's a pretty slippery teardrop design so it doesn't present a lot of frontal air resistance.

Uhaul 6x12 is 2290lb. Golf cart is 900. 3200ish total. Empty, it's 26" high. Golf cart with the windshield puts it at 86". Efficiency 2.0, speed 55.

Got it, thanks for the updates!

Who’s next?

 

[Maximum Effort]

I have towed with both a 2022 lariat ER and my new 2024 flash. I have a 16 foot enclosed trailer that weighs between 4,000# - 5,500# depending what’s in it. It is tall as it has a 6’6” ramp door.
I have a 12’ dual axle dump trailer that weighs between 3’000#-7,500#. Again depending on what is in it.
I also have a 12’ single axle utility trailer that I use to move a tractor (w/ cab) that weighs about 5,000#.
Going between 55 mph on secondary roads/ 68 mph on highway, I consistently get 1.0 regardless of what trailer I am towing. It has gone down to .9 in heavy rain and wind and up to 1.1 (tail wind)
I absolutely Love how the truck tows and am happy with the range of the ER battery.

I have an ER Lariat with the Max Tow package and although I have 7,000 miles so far, this was my first trip that required charging from anywhere but home! It was also my first time towing my Taxa WoollyBear racing/camping trailer which has a dry weight of 2,000 pounds. I guess I have another 400 - 600 pounds of racing/camping gear in it as well. I did a test run and saw ranges from 1.2 - 1.6 mi/kWh. After adding more weight and traveling ~250 miles, it averaged out to 1.4 mi/kWh. I ran 5 miles over the posted speed limit with a maximum of 70 mph.

FWIW: I loaded my test range into ABRP and it seemed to predict my end SOC pretty well as we reached the destination. I used a DC fast charger once arrived while my family was settling into the hotel so I wouldn't need to charge on the way home, but the truck kept trying to put a charger in my route. I wish appropriately registered "home" chargers would be known to the software so it could be the charging destination. (Oooh - maybe I'll use the "recommendations" app in the truck to suggest that...)

20ft bass boat with gear…3100lbs I average 1.7kpm … between 55-65 mph ….gom usually tells me 220 miles… and it’s pretty close …. There is a lake I fish that’s about 180miles round trip

I have some scientific data to contribute. Towed my single axle boat trailer, with 6m jet boat. About 1600kg combined mass. 241 km round trip, used 448MJ of energy travelling at 30.5 m/s. Ambient temp about 304Kelvin so max A/C running the whole trip. That's 1.86 MJ/km. Not sure what that is in your units.

6m = ~20ft boat.
1600kg = ~3500 lbs
241km = ~150 miles
448MJ = ~124 kWh
30.5 m/s = ~68 mph
304K = ~87 deg F.
1.86MJ / km = ~0.831 kWh/mi. or ~1.2 mi / kWh

Uhaul 6x12 open trailer with a golf cart in it.

Irvine to Palm Springs to Irvine (234mi).

Leave at 100%, pull in at 10%. 55mph the whole way.

Use forscan and turn off that stupid “full view” message.

Thanks, guys! Added to the spreadsheet.

We’ve done a lot of towing with our Airstream Classic (25’ long, 8.5’ wide, 9.5’ tall, 7300 lbs loaded). We average 1.1 mi/kWh at 65 mph. We don’t typically tow any faster. We’ve increased efficiency to average 1.3 mi/kWh at 50 mph (long stretch between available chargers).

I have always hated the made-up unit 'Kilowatt-hours'. That's not a real unit, folks. If' we're just makin sh*# up around here, I choose horsepower-minutes.
