Road Trip Tanked Estimated Range

[DerekS]

My car is RWD with PB+.
Charging at home, I've seen 85% range of 250-260 miles, and around 290-300 at 100%.

I took a lengthy road trip over the weekend (details in the trip reports forum) where I had a ton of highway miles at reasonably high speeds.

Now after getting home, my range is down to 200 on an 85% charge.

I have to assume the estimator is just out of whack with the large highway trip and it will recover, but it was a bigger drop than I expected.

Strange. One can‘t blame the cold in Texas, I suppose? Did you drive at a very high speed during your road trip?

I had a similar experience, after a 1k mile trip I am only getting 170 miles on an 80% charge. I hope that at some point it reverts back to higher numbers

It should recover.

Welcome to my world - this is my norm for Autumn through Winter!

...some say Porsche are sneakily tweaking available range OTA without us knowing...could start a rumour

I have a similar experience but even worse than Your result. I drove nearly 3000 km through Europe last week. My range has also dropped a lot. Even after driving around 250 km here, where I normally had a range of 320 km at 80% SOC, I now only have 230 km. The temperature has dropped some 5 to 10 degrees Celsius, but I am surprised at the huge drop.

Our return trip was all done on fast motorways with the last 1000km at 130 km/h but still. I had expected the range to start climbing again driving locally some 250 km, in 18 to 20 degrees Celsius. But no real difference As yet.

It would equal about 290 km range at 100%, which would be a very low figure in my mind.

The car is going in on Monday for a third time to check the connectivity, LTE and Connect problems, as well as trying to restore my Innodrive. I will ask them to check the main battery.

Here's a question from my lack of knowledge that I'd like to better understand:

Do trips like this affect the battery percentage presentation or only the range projection? If it's only the range projection, it's likely just an issue with their calculations and the way they present it and it's thrown off because of the out of the ordinary large trip similar to any basic averaging would.

If this is somehow also affecting the percentage available on battery and you're seeing it drop faster now that is a bit more alarming. I'm only 1100 miles into my Taycan, so I don't know enough about the range calculator/projection and the available battery percentage presentations to know if they are both augmented after long trips like this, so I'm asking out of curiousity.

No difference really in percentage presentation, just range. I could not travel the same distance between chargers that I could a month earlier. The difference in actual range decreased by some 25 to 30 %. Route along motorway at same speeds but opposite direction.

~100

 

[Kingske]

~100

That may explain it. Consumption increases rather dramatically above 80 mph. 100 mph is a perfect cruising speed for a Taycan but at the cost of range. The good news is that your typical range will be back soon enough, assuming that you are now back in your typical pattern.

 

[Scandinavian]

~100

Let us know if the range builds once you are back driving your ”normal” pattern:?

I can understand how projected range calculations might average out based on changes in real world driving habits, but it makes no sense at all to me that actual maximum driving range would decrease just because one took a long trip. I'd love to hear an explanation as to why that might happen.

Hard to explain exactly without knowing the algorithm used, but it is likely that the actual average kWh/mile consumed over the previous two to four weeks is used to predict the range going forward, together with a large number of other parameters. Since such historic consumption is measured on a rolling basis, the predicted range will gradually revert back to the earlier number.

Thanks, though I understand how an algorithm used to calculate expected range could change it's range prediction based on data from real world driving and how it could then change again based on subsequent data.

What I don't understand is why taking a long trip would affect actual range as was suggested by the experience @Scandinavian related in an earlier post. Maybe I misinterpreted something.

I get your point now, thanks. Would actual range not be very actual speed dependent?
