10,000+ Miles Driving a Cybertruck – Things learned: range, great sound and full love/hate list after 10k miles

You beat me to posting that, a few people on X have already substantiated the numbers with how the Tesla calculates. Also way to many other posts, reports, videos, and livestreams in that same ballpark with people being able to extrapolate it.

I would assume if it was incorrect it would be easy for Wes to report the wh/mile of the top 10 CTs

Unfortunate that they did not link to the thread/forum in the original post but in a reply.

Wes has had his hands full with the Porsche racing vid controversy so no hard feelings, hopefully he can release the total avg wh/mile and miles driven on CTs it would be an awesome data point.

Lmao, you guys love getting lied to.

he did get kind of softened there ?

I didn’t see the largest variable in EV efficiency stated - tire pressure.

I’ve been banging this drum for a minute

and if you think it’s important in a M3, try it in a BEV truck


That said, can’t help but say it: bunch of these same dudes didn’t want to hear it when it was about ragging on an F150 Lightning

I tried googling and found a good source. Underinflation causes a 2-4% loss in one test depending on speed. Wonder if this gets worse with AT tires.

CT takes 50 PSI which is pretty high compared to other similar size trucks.
Good news is it shows not only the recommended but live tire pressure.

Knew I had seen it somewhere.
Image below posted on IG just yesterday, not sure what pressure was during big range drive report but would have had access to it and based on other Teslas think they would have gotten an alert if pressure was high or low.

I can tell you from many years of experience, this is partially incorrect. 2-4% may be accurate at slow speeds, but friction is a multiplier and it will have a larger effect the faster you travel.

Also, I missed that OP is in Norther Michigan- another factor at play is snow and ice. I can tell you that on a newer Tesla with a high efficiency heat pump, cold is not detrimental but snow and ice buildup absolutely is, as is the road surface. If you let the wheel wells fill up you’re potentially adding hundreds of lbs of weight, killing aerodynamics, and salted/dirt/gravel/sanded roads still cause additional energy usage (but not as much loss as icy roads).

the link I sourced had a test at higher speeds that showed a 4% loss.

here’s a SAE article:

“And ExxonMobil Chemical road testing has demonstrated that EV range can be improved from 3-7% with optimized tire IPLR.”

Saw this review getting called out on X, I find the numbers highly suspicious, giving it 1/10 shot of being real.

123 kWh/320 miles = 384 Wh/mi rated range
123 kWh/340 mies = 362 Wh/mi rated range

10k miles in this short of a time means lots of long distance highway drives, which often tends to be better in the real world than many short drives because the cabin/battery get conditioned for max efficiency.

In my S, on summer days driving 70-75mph average trip (read: this is actually hard to do on _average_, means trying to cruise at 85 as possible) I see deratings of 15%. Now "summer" for me doesn't really compare to Florida, should be warmer and more humid (less drag) more of the time there, and "summer" is just when I keep my summer tires on which is right up to the night of the first snow storm, which this year was a whopping January 6th, 2024. This data was collected with teslafi.

15% derating comes to 362/(1-.15) = 426 Wh/mi

Not buying 599 Wh/mi

Would suggest reading through the big pile of replies on X, some are tribal from one side or the other but quite a few help substantiate the #s and some are pretty detailed.

The one disagreement I would have with you is that for BEVs highway driving is almost always WAY worse efficiency or Wh/mile than city driving. Some of the reports we have seen Wh/mile as high as 800 on the highway, which again helps explain the overall average.

wasn’t clear what vehicle or its weight was being referenced

as weight increases, the effects of PSI increase

anyone doing a tow test without reporting their PSI / that they overinflated before towing, is sus

If you have temperate conditions and leave the HVAC off, then "city" can be better than highway. What's actually better than highway is rural/extra-urban areas where you just cruise at 35-45 mph for long distances, as in the limit consumption is just a result of drag.

What actually happens in the "city" is that HVAC ramp up, battery preconditioning, and excessive starts/stops take a huge hit. I had a drive last monday derated by 62%. Of course, small number of miles, but still.

PS, EPA test cycle sucks.

HVAC blasting at full power (like preconditioning) is no more than 2-3kW. That's 'like' going 6mph. (not exactly since there's other overhead, rolling resistance, air resistance, which isn't a constant.)

So it hardly matters against your speed.
