Why are Tesla's range estimates between Cybertruck trim levels so close?

[Leifmb]

When Tesla first added dual motors to the Model S they said they noticed it gave better efficiency having all the motors engaged, I would assume the same would be true for a tri motor(maybe not to the same extent) but I’m betting they are all engaged while on the highway.
I’d like to see a comparison on the AWD and CB with it set to standard, and not letting the driver know which is which and see which one gets better range.

The model x/s (tri-motor setup at least) use permanent magnet motors which require energy just to spin them. On the CT, they use one perm and one induction on the dual and one perm, 2 induction on the beast. The induction motors don't require energy* to spin when not energized therefore being more efficient but have less potential power output than perm mag motors. Thats how the CT uses only one motor while under low load driving down the highway/road.

Anecdotal ... These are averages from TeslaFI-COM for the DM and Tri on their range leader board.
I was mainly paying attention to Wh/Mile.

Well that is significant.

I went into my TeslaFi account and averaged the DM and TRI leaderboards myself. Came up with similar numbers:

DM Average wh/Mile: 391.2
TRI Average wh/Mile: 469.1

That's a difference of nearly 20%. These real world numbers are definitely food for thought.

not surprising. there is a similar delta between the dual motor Model S and the Plaid. Running an extra induction motor does take some juice.

Wow, 469 - Beasts are using some juice! With my beast I dont frequently Hoon around like a teenager but I do a lot of 80-90mph and my 9k mile average is around 450wh/mi....so some of you are definitely leveraging the power curve! . Kudo's! Tesla Winter tires (same weight / same AT wheels) but different tread/compound = 10-15% range loss from what I've seen.

I think driving style and trim may have some correlation so be careful using average wh/m to compare the vehicle efficiency. It would be more interesting, I think, to see how the efficiency vs speed compare between the CT and CB.

I could not figure out how to get TeslaFi to report efficiency vs speed for all CT and CB but here is the data from my Beast:

I think this data is efficiency for the entire trip and the speed is the average for said trip. I say this because half of my commute each morning is at 74mph and there are no entries above 65.

FYI, there are some duplicate entries that I removed so that is why my counts are < 50. My % diff is similar at: 17.35%
(BTW, I did open up a support ticket on that dup problem).

That is a great observation related to your partial commute speed being > max in table.

I could not tell that from my 2017 Tesla Model X 100D. I've done a lot of roadtrips so that may explain how I have a fair number of miles in the 65-70 & 70-75. ala. exit not far off highway to a supercharger and then getting back on and cruising at 75-78.

I'm at 336 Wh/mi in my AWD CT since June (5+ months, 3,800K miles) so largely summer and fall here in the northeast. Consumption is trending up as the temperature drops, I was at 332 Wh/mi at the end of August. Coming from the Plaid, I often use the power when road conditions warrant.

I do check tire pressures regularly and adjust as needed. Don't hold back on the power when the road opens up and that's probably about half highway travel at 65-75mph.

I am mindful of charging, my daily limit is 70% and I have very little Supercharger use (<5% per the app).

I don't have conclusive data to share, but anecdotally it seems to use less power in low ride height, firm suspension than medium/relaxed. Could just be temperature/conditions but would be interested to see if anyone has done real testing with the different suspension and ride height setups.

Oh, and I'm always hauling the Tesla spare wheel and tire in the bed adding weight.

Aside:

my AWD CT

Unclear why you use "AWD" designation all over the place since both Cybertrucks powertrains are All Wheel Drive.
Is yours a DM/Dual-Motor or TM/Tri/Tri-Motor Beast/CB?

Because in the earlier days of CTOC the vernacular to distinguish between the dual motor and tri-motor was AWD or CB.

Just FYI I have a FSB. On average I'm running about 395 wh/mi. I think it's all in how you drive it.

Thx. What % of your driving is > 60 mph?

Quite a bit. In fact I take a hit for over 70 mph frequently.

Hi All, I'm new to the forum. Considering trading my M3 for a Cybertruck. When I bought my 2021 M3, it had significantly higher range (353 miles) compared to the Performance (315 miles). A 12% difference. For Non-FS Cybertruck Dual and Tri motor variants, both equipped with AT Tires, the range difference is only 4.3% (314 vs 301 miles). With the lighter core tires, the difference is a paltry 1.5% (325 vs 320 miles). It might be too early for this question, but are people getting a sense that they can get these kinds of ranges from their Cybertrucks? Considering the weight difference between AT and Core tires will result in a 2.8% range hit on the tri-motor, do you think introducing a heavier AT tire like a BFG KO3 would cause a larger range hit on the Tri vs the Dual? Thank in advance.

BFG K03 is worse range than OEM AT.
