Set at 110% Speed Limit but there way also traffic at that time of the day that ABRP isnt using.

Yep looks about right around the 400Wh/mile mark as expected from our other calcs as well.

Who knows how else they nerfed the software to foil "reverse engineering" from the screen numbers and keep us guessing until the actual release versions are available?
100%. The disinformation campaign could be strong. Maybe they just linked it to the ABRP calculator (which isnt it owned by Rivian now?)
Sometimes, I miss the pandemic
I will tell my grandchild of the the days of no traffic and new personal top speed records.
7.2kWh used with a 6% depletion would yield a 120kWh pack. Reversing this again yields 267mi. If we use 2.5mi/kWh then that should be 300mi even.
Yes, some where in the range of 115-120 usable kWh. That's if the GUI isn't disinformation and just linked to the dual motor cybertruck on ABRP. lol

If they couldn't even deliver the 350+ for the 2 motor thats not good. I can definitly see that being a 50K price @ that range but I won't be a buyer. I have a feeling the TRI will have even less range using the same battery pack. No wonder they removed the resale penelty already.

Without knowing the specific Crr of each tyre I'd only reasonably expect between 5-10% range reduction between the street and ATs. Both tread patterns would be range optimised, read: AT will be off-road compromised as a result and not as capable as other ATs.

Expect 300-320 best case real range.

But we could add some aero upgrades to improve range... ;)

Do we think the topographical geometry is being procedurally generated from camera inputs or it's just there to look cool?
It’s “Westlake Hills” not “Westlake Mountains”

To be fair to Tesla, the dual motor announcement spec for range was 300+ miles, not 350. If they exceed 300 miles they are matching the announcement spec for that model.

Of course we all want more then that, especially if there is no 500 mile tri motor version at launch, but if you pre-ordered a dual motor it was with the understanding of a 300+ range, not 350.

Out of curiosity, how much do you reckon removing the side mirrors would be good for?

Separately, what other aero upgrades did you have in mind?

Definitely produced by the onboard cameras but probably not accurately in these images yet?

It will be interesting to see it identify terrain in detail for a detailed 3D view whilst off road.

The tiny details might matter here.

Displayed SOC on the screen for 71% on the BMS could be anywhere from 70.5%-71.4% a 0.9% margin of error. That also means that arrival SOC has same margin of 64.5%-65.4%.

If you take the absolute worst case scenario that is leaving at 71.4% and arriving at 64.5% you get 6.9% battery used to travel 16.3 miles.

16.3 mi / 6.9% = 236mi of range

Now lets take the absolute best case scenario that is leaving at 70.5% and arriving at 65.4%, in other words 5.1% battery used to travel 16 miles.

16.3 mi / 5.1% = 319mi of range

The trip computer also takes into account recent driving behavior which can further exacerbate our calculations. If the driver's efficiency is consuming 20% more battery than EPA range you can easily see the calculations growing more uncertain.

All I am trying to illustrate here is that there are some large error bars when calculating range with limited information.


Any battery experts ( @JBee ) want to break these down?

The flux capacitor option uses quantum aero and is being developed by the accessories team with the help of Doc Brown.

I'd say up to 2% as these would also be aero optimised. It's not like they are slapping truck mirrors on there, so the difference between with and without might not be that big. The wheel covers might do more.

There are a couple ideas from inflatable front "Aeroobars" that offer wildlife protection and better aero, to revised front skirt with active lowering skirt for freeway use, better air curtain design around the wheels, or a rear wheel well cap, and a pop up roof that can streamline to a trailer box etc.

Agreed, hence the bag of salt comment.

But we also have other factors we can consider derived from the pack design and available space in the CT etc, plus some leaks that all point towards the same numbers, that have all their own sources of data. Taken separately these might not be meaningful, but assessed together, one would assume they are probable.

So like just fold the air out of the way? Brilliant. :)

If there is one thing the SS panels is not helpful for it is aerodynamics. The less aerodynamic it is, the more such mods would be beneficial. It will understandably change the look of the vehicle, but it will increase range, so if you can package it into something that is otherwise useful, the net outcome might be positive. Like the rear aero cargo box etc. adds range that not only offsets carrying extra load but also adds miles. There's already a box like that for the M3/MY.
