Cybertruck VIN decoder! -- GVWR Vehicle Weight Revealed + **only** Dual and Tri Motor for 2024

[TheLastStarfighter]

This is likely because it has a larger 120kWh or so pack, because it also needs more energy to go +300miles.

Do you have a link to this story?

Wasn't a story, it was a Twitter spaces conversation.

They are also not the same type of motor at all.

They normally put the cheaper less efficient higher power induction motor in the rear (that don't have magnets) and put the higher efficiency lower power PM motors in the front. That way they can turn off the rear motor electrically to avoid efficiency losses without a clutch, whilst they cruise along with the more efficient PM motors on the highway under low power. You can't turn a PM completely off because it always has a rotating magnetic feild from the permanent magnets. Essentially if you spin a PM you are regening energy, and it's slowing the vehicle down.

This is also likely why the semi has a clutch on the rear motors, because it uses the Plaid CF wrapped PM motors with magnets. Not the CF wrap doesn't cost much, but is there to reduce the airgap between the rotor and stator, which in turn reduces eddy currents and losses, whilst also allowing it to spin the rotor faster, without it increasing the rotor size from centrifigal forces and seizing in the stator at high rpm. Now higher RPM means more power from a smaller and lighter package, and is where the Plaid gets its extra oomph, and is why it has a higher ratio driveline gear.

I'm pretty certain they have perfected the CF wrapped Plaid since, and are not only getting better performance but also doing it at a lower price point so they can use it in every successive model, including the CT DM and TM.

uh, where did you hear the motors on semi are clutched?

so that the thread of thought is a bit more disconnected here:

consider one of your last questions to me elsewhere

95% of the 1.31 million Tesla cars sold in 2022 were Model 3 and Y

OF that other 5%, or 65,600 units, only some fraction were Model S - let's be generous and assume 1/2, so 32,750

Of that 32,750, only some further fraction were Model S Plaid - let's be a bit more concervative here and assume 1/3 - or 10,000


Which is to say, to the extent the CT utilizes related 'performance' hardware ... scaling

that's another constraint (in addition to batteries*) that would inform the build mix of dual-to-performance varient




*while they have the same pack, size, where to put limited battery resources is a question of volume (e.g., if there is a bigger market for duals, you make more duals)

I actually thought along the same lines after I posted that about the Plaid motor.

Maybe someone made a last minute decision to go CF motors for the CT, and they haven't got the line ready for CT production?

As justification for making the change, they had the battery shortage anyway, and maybe the tuning of the RCs with CF made them put the TM on the backburner a bit? What's an extra second to 60 between friends?

So making a 300 DM would make sense from both limited batteries and limited CF motors that way. I don't think they would have gotten away with a single motor as the first delivery. Would of been a flop, and the dual matched their 4680 ramp best.

Warning, my electrical/battery knowledge is lacking:

Given: 4680 Cybercell (Gen2): 3.7V 25.7Ah = ~95.1 Wh

1.) If we had a pack with 216s6p ~115kWh usable, what would be the peak pack power?

2.) If it was 216s7p ~ 134kWh usable, what would be the peak pack power?

3.) If it was 216s8p ~ 153kWh usable, what would be the peak pack power?

I found this website but some of it is going over my head and other parts I think might be incorrect.

Unlike batteries that would be a self imposed limitation. CF motors are a solved problem.

Solved problem?

my hypo is that if to date they’ve been making 10K a year, it’s no small thing ramp to make an additional 62K/year (required to have a dual/tri blend of 50/50)

By that I mean they know how to make them, it would be a matter of adding capacity. If the expectation is that the tri motor's appeal will be low due to its range/price then it makes sense they would not be inclined to make that investment.

roger that

I can see some people wanting to finance FSD but in my case, as long as Tesla would keep my FSD at the same price as it was when I put down my deposit ($7,000), I'd jump on the option to skip FSD at time of purchase to get the $7,500 instantly and then, the next day, I'd buy FSD for $7,000.

You can always put more money down?

The Semi delivery event, 14:25.




-Crissa

And he says they're 'basically using the Plaid carbon overwrapped powertrain' so maybe that's alot closer to the Cybertruck than I thought.

I don't appreciate you correcting the record.

but it's noted.

 

[AustroTom]

there.

is.

no.

500mi.

version.

(for now)

so let's direct the maths outward from that assumption, if we're trying to divine weights, etc.

Who says??
