Range vs. Temperature question

[Ccham_36]

Hello,
I bought a used 2023 Taycan base in July. We live in NJ so temps in the 90s in July, now, October, overnight temps in the 30s and 40s. When I first got the car, a full charge was showing a range of 268-273 miles, now in the cooler temps, only showing 235 miles range when fully charged. The car does not have the extended battery, is this normal? Also, the car was part of the HV heater recall, could that have anything to do with it?
Thanks
Chris

This sounds about the same % drop as mine. I go from 245/250 dropping down to 200/210 in the colder months.

Thanks, I am new to this so wasn't sure if it was normal.

20% drop summer to winter is about the norm for my car in the UK, which is not as extreme as your weather.

This is 100% normal (for any EV make / model) - higher ambient temperatures then the greater potential range on offer.

Ignore the range reading, always check your consumption numbers (Total Since) - should be around 2.9 miles / kWh to 3.2 miles / kWh for first generation Taycans (smaller capacity battery) depending on conditions.

HV heater recall 100% unconnected (more to do with a potential future failure of the heater (cold cabin)).

In my car the "total since" is not credible.

I check every trip, and they vary between 2.0 and 2.7 with quite a few short trips below 2.0. I have done only one of my long trips at 3.0 in the last year the others were 2.7 at best, so it is mathematically impossible for my average to be even 3.0, yet the app reports 3.2 which is completely at variance with any possible reality.

It is one of the only aspects of the car which is obviously wrong, broken, rubbish, pie-in-the sky - and irritating.

I certainly do not trust it and would advise others to check if their overall has any credible association with their normal trips and be cautious what they believe.

It may be only on my car but my "total since" is total rubbish.

They are credible if you don't reset it. Total Trip I have left in place since day 1 and gives an accurate average over the total period of ownership. My GTS (UK Scottish weather) - 2.7 miles / kWh since 2023 and my 4S before 3.1 miles / kWh (over 2 years).

What you aren't seeing is all the telemetry data to make an accurate call on this (nor am I).

Doing short trips is as good for consumption as it is in an ICE vehicle - the worst possible thing!

My total is since I bought the car.

You don't need to be a mathematical genius to understand that a plethora of readings over 2 years mainly between 2.2 and 2.7 with a few a lot less and a single one at 3.0 to work out that the average can not have been 3.2, and I am quite good at maths.

I did consider making an average of all the data myself ignoring just the short trips which are bad on consumption but short on mileage but in the end did not because it was so obviously only possible to check how wrong it is, probably 10 to 20% optimistic.

2.7, I could believe but 3.2 as an average of a data set with a single maximum data point of 3.0 is mathematically impossible, so I don't believe it and IMHO, nor should anybody else.

I understand but we don't know how "Porsche" calculate it - perhaps they exclude short journeys etc and of course it could be a 'bug'!

The short journeys don't have that big an influence on overall miles/kWh since the miles figure is so small. I could easily believe the individual measurements could result in an average around 2.6 to 2.7 on my car data. But 3.2 would be impossible.

It could be a bug, but either the individual calculations or the overall are wrong, or both, of course.

There are a thread or two on this. You are certainly not alone having the app consumption figures be well in excess of reality. My lifetime is 3.5 miles/kWh. That has happened but it's rare. Most of my mileage is highway where I average 2.9 - 3.1 miles/kWh so any weighted average would be well below 3.5. What the car displays for consumption during a trip seems pretty accurate - miles traveled in relation to kWh used. The lifetime figure gets ignored.

It is not just your car that totals are way off. Mine says 3.7 mi/kwh which is impossible. There is another post in a recent thread about good range which shows a total of 3.8 mi/kwh for a Taycan RWD which I find unbelievable, as well.

Before I read that, I was puzzled out to how our interstate-speed range kept going up with hotter temps, despite more AC use.
The answer is that the lower air density in hotter temps makes a big difference for EV efficiency at higher speeds.

My latest 500 km trip was 2.39 miles / kwh (or 26 kwh / 100km in non-freedom units); average speed 90 km/h

Total since begining, is 4.78 miles / kwh. Which seems accurate, accounting for all the 50-80 driving ones has to do in Switzerland, and all the going downhill.

So for me seems to work fine.

So far, for me, going from 35C degrees to 15C degrees resulted in 0 range loss. But as temperature drop, it will for sure result in range drop also. Hopefully offloaded a bit by 20 inch winter wheels.

Warm temperature giving most range, but also deteriorates batteries faster than mild weather.
I wonder what exactly drives this behavior.
