Tesla Model 3 - V3.0

Excellent - thank you!

For ease of calculations it is best to take a picture of the TRIPS menu when as soon as the battery is at 50%.

Good luck!

Thanks - figures look good! Ties in with what i'm seeing in mine - allow for a bit of rounding and we will call it 52kWh. Bang on with what Tesla have told me and what i'm seeing in my own car.

Bear in mind that 148 wh/km was an efficient drive compared to your overall average efficiency of 160 wh/km

My efficiency has settled around 154 wh/km but i do a good bit of motorway driving and i've put nearly 3000km on her already.

But sure that's like saying why don't we just have a 40kWh battery and that doesn't make any difference that a 50kWh. Of course it matters - ok the margins may be small enough but it all counts.

I understand that it may be a battery management issue but if you need to pack in a 60.5kWh battery to only have 52kWh usable, that seems crazy.

There is already a 2.5~3kWh "hard buffer" on the LFP's so adding another 6 seems excessive.

However, more to the point is the advertising - Tesla increased the WLTP advertised range 409km to 448km to 491km over the past 3 years. I want to know what the 491km was based off as it coincided with the usable battery for late 2021/early 2022 models being increased to 57kWh (4.5kWh buffer). That's the range that i was advertised and bought. However that range has been reduced by reducing the usable battery size to 52kWh. On the face of it the product has been mis-sold with an incorrect WLTP range.

I understand where you're coming from, but as far as i know Tesla don't advertise battery size in their specs, so technically they're not misleading anyone. It is a 60Kwh battery but they currently have it locked as a buffer & will probably unlock the additional buffer in the future

Next software update I believe the "energy" app is going to include all of this data.

However on a dry day, no Aircon, no phone charging and no sentry is when I've done the tests so very little in reality is going to anything other than powering the car.

As I've said before tesla have actually confirmed the massive buffer to me. Just looking for confirmation from a wider sample size that got rwds delivered in September 2022.

Quick question.

Tyre size on the car is 235 35 20.

Anything stopping me from going 235 45 20?

Basically forget about trying to extrapolate out from what your charger says or the cars says when it comes to charging, you're guessing with waaaay too much margin for error.

Either:

Get tesla to verify your usable battery

Use the scan my tesla app

Or do the real world test I have outlined last night

Cheers.

No one yet has been able to post any data to refute my calcs using any of the above parameters so it is looking like September rwd m3's are all at a usable battery of circa 52kWh

Sorry but that's not what we are looking for.

Out of interest what did u get charged for I.e. in the app how many kwh were u charged for?

If u have a screenshot of your trips screen before u charged that would also be interesting

App says 54

Sorry but you don't really get it. RWD delivered early 2022 has a WLTP of 491km. RWD delivered in September also has the same WLTP but approx 5kWh bigger buffer.

So the 2 can't be the same i'm afraid for WLTP. Although Tesla don't advertised battery size (lack of transparency but thats for another day), the WLTP range has the battery size as part of the equation.

The only way i can match the same range as the early 2022 deliveries (that were advertised exactly the same for WLTP) is to drive waaay past zero.

You are also making assumptions on future degradation coming out of the buffer and we should be delighted about that. I'd take a longer range right now and it degrading to the current range over time - i think that's a bit of a no brainer and your argument makes zero sense in this regard.

Thank you.

FYI on a usable battery of 57kWh (early 2022 RWD's) you would need to average 117 wh/km to achieve a WLTP range of 491km - so 8.6km per kWh

On a usable battery of 52kWh (September 2022 RWD's) you would need to average 106 wh/km to achieve a WLTP range of 491km - so 9.44km per kWh.

I mean i don't think i can dumb it down any further.

No wonder Tesla don't advertise battery sizes alright then you might actually be able to question their figures in a transparent way.

Anyone here know a 491km route downhill so i can get 106 wh/km.....................

Yes i would.

Best I've seen on a trip in mine was 118 wh/km but that was a round trip so allowed for elevation both ways - i couldn't go one way and teleport the car back home for me. But that really is very very slow and careful driving.

What size is the battery pack in the FM SR+? I presume smaller and more importantly lighter so i'm assuming capable of better efficiency. So unless you can do it in a RWD 60.5kWh pack, i don't want to know lol

Took the recommendation from someone on this forum to visit Padraic/John in Flawless Detailing, very impressed with the job.

The guys were excellent, and did PPF on front, A pillars, rocker panels, lower doors and cargo area, coating the lot in Xpel fusion ceramic.

I got a call from Padraic with videos of some defect contamination he found on the passenger side, tiny specs all along the front of the car. He was able to polish them out to the point I could not see them. I guess it will never be this clean again :D
