Tesla Model 3 - V3.0

No. The radarless tesla vision is worse than even AP1 that was in my old S

I do that trip at least once a week and find AP is great (2021 refresh SR+ model). The only problems I have on that trip that you mention is when passing through Althone as there are some poor line markings in the off-ramps. AP will improve the more you drive. Still running 2022.20.8 update at the moment.

Have used very little AP since i got my car, only ever used it to see what its like, i find traffic is too heavy to get the best out of it, have to overtake too often(if i had the auto lane change it would be better, but not paying for that)

I find the distance gap of the adaptive cruise control varies alot, sometimes it slows well before you catch the car ahead, and other times it closes right up(even with the same distance setting) its become a lottery as to when you have to pull out before you start slowing down, i feel you have to be in the overtaking lane an age to overtake something thats 3-4kmph slower than you.

Descided to give AP a decent go this evening on the way home. 40km on the motorway. Drove at 110kmph so I wouldn’t need to overtake as much.

it worked very well. Only disengaged once as I probably too firm with the wheel to say I was still there. Can definitely see the benefit on a long boring journey.

on a side note. I am finding the phone charge pad hit and miss. It seems to only work sometimes.

I have a iPhone 12 mini so it’s smaller that most phones these days. I am wondering it’s too small. I tried holding up further on the pad to see if it would kick in but no joy. Might remove the case and try it again.

It’s a Apple MagSafe case. So not thick. Will try without the case for a bit when I get the car back, the wife has seconded it. Might never get to drive it again.

If you account for rounding and say that 52kWhrs is spot on then your battery capacity is (52/85%)*100%= 61.2kWhr battery size

If you round up from 51.5kWhrs then is it (51.5/85%)*100%= 60.6kWhr battery size

Looks very healthy either way...

The rounding on energy charged gives you an error of +/- 1kWh and the rounding on %SoC gives you +/- 1% ~ 1kWh. Overall +/- 2kWh

Going back to the figures 52/kWh /.85 = 61kWh +/- 2kWh => 59-63 kWh. You need more resolution to reduce this uncertainty. The figure from Zappi can only confirm that is in range so can't really help. Does Tesla state somewhere in the contract the battery capacity? I can't remember seeing that value when I got mine.

I agree but it's a lot better than trying to extrapolate out figures from the app or your charger as there are way too many variables there and unknowns. I'd say if you could look at the coding in the Tesla app you'd be surprised where it gets its figures from, that's all i can say on that.

Drive from 100% to 0% during the day with no heating or lights on and no phones plugged in or whatever and your energy consumption will be very close to the actual energy used. I've seen videos online and this is certainly the case - also remember that the M3 has a heat pump which drastically reduces the energy the battery used for heating the cabin.

If you want an example of this, take a look at this video below - i have timestamped the link to the exact part - ok he didnt drive to 0% but he has extrapolated out the real world test and uses the trip data as his source. I did the same test yet i drove to zero and could only manage 51kWh - this also ties in with what Tesla have told me is usable.

Yet in the above video in a car delivered approx 10 months earlier than mine the usable battery is closer to 57kWh. So quite obviously a way smaller buffer in the end of 2021 model.

Tesla have decreased the usable battery size by approx 5kWh since then (or at least in my particular car) but they have not decreased the WLTP advertised range. Maybe they expect us to all drive to about -10% to achieve this.

Last night it said it took 57kWh from 5% to 100 which just isn't right. I genuinely think the app just works off 100% = 60kWh and works back from there which is totally misleading.

Let's take today for example. I charged to 100% and drove down and back from Dublin with no a/c and no lights. 30 mins stop off to meet a man about a dog and then straight home.

At 50% remaining I had used 25kWh energy but it was at 25kWh for a few minutes so probably closer to 26. So extrapolated out that's almost 52kWh if I ran it down to zero. Totally consistent with what tesla have told me and from my own previous tests.

I'm still waiting for others to post figures on a similar test but no one has yet.

If someone can post some energy usage on a similar test showing more that 52kWh energy usage then I'll definitely be getting back on to tesla. I probably will anyway.

My average energy usage is 150 wh/km which equates to 6.67km per kWh

That means for me the car is a 345km range without having to drive past zero percent. When it should actually be 380km if the battery had a usable capacity of 57kWh like late 2021 lfp have.

Like the battery capacity is 60.5kWh and the usable only 52kWh so I'm lugging around extra weight that can't be used. The buffer is pretty crazy.

I'd appreciate if others could actually post some stats from their trips but no one seems to be coming forward yet but are happy to question my calculations without actually providing their own evidence.

Ant takers?
