Battery life & range

[MY22PCT]

I thought I’d share my positive experience and views on battery life.
I have a Taycan Turbo S Cross Turismo. It was one of the first, registered March 2022, and I’ve done 84,000 miles in 10 countries.
in December I asked my dealer to perform an official Porsche SOH assessment on the HV Battery. It scored 91%.
Using a battery degradation curve, rather than straight line, my battery is likely to get to 300,000 miles at 70% SoH.
My current 91% or close looks like this: I drove 203 miles today in range mode. I have 9 miles range left. The journey was a mix of motorway (90%) and country roads. I used Porsche’s adaptive cruise control nearly all the time. The temp was 10-13°C, I started at 100% charge and I’m still on 20” winters. I drove gently.
Generally, my battery mgt looks like this: 95% of charging on a 7kWh home charger to 85% capacity. I use high speed chargers on longer journeys but I tend to use the PCM so normal charges are top ups for a few minutes.
I thought this real life info and experience might be useful and/or interesting.

Great report and generally accepted understanding that the battery will outlive the car and will retain 70%-80% of its capacity long term with BMS doing a good job taking care of the battery.

The only wrinkle in this equation is that if battery modules start to go bad and you start going down the path of replacing them or the entire battery, then you are stuck in a base Macan for months while waiting.

Did your dealer charge you to perform the official SoH assessment?

Thank you.
and no, they didn’t… which surprised me. I received a signed letter/certificate which (I guess) they provide with their approved EVs.

Very helpful. My dealer is struggling with this as they cannot move used Taycans without spending at least $1,000 of their time performing this official procedure per corporate to create this report that customers demand.

UK dealers run it for free. Mine is MY21 and my SOH was 92-93% if I recall.

good. And your mileage?

Just wondering. If the battery outlives the car then what would be the thing that breaks down the car?

This is a really good question. And this is my thinking…

- if you buy extended warranties then you don’t really care
- in the UK, Porsche will sell extended warranties until the car is 15 years old or until the car has done 125,000 miles (at the start of the warranty)… whichever happens first.
- I do 21,000 miles a year. I’ll buy another 3 year extended warranty just before I get to 125,000 miles. The car will be c6 years old at this point. As a result, I’ll be covered until the car has done over 185,000 miles and is 9 years old.
- when my last extended warranty has expired the car will be worth, relatively speaking, a very small amount of money. Then I’ll rethink my relationship with the car. I will only have paid for wear & tear items: tyres, maybe brake pads, 12V battery, wiper blades, cabin filters, fluids, suspension wear.

Lots of things. Most worry about the battery but that is the only component that is warrantied until 8 years or 100k miles. We are in consensus on the forum that no one should be driving the Taycan without factory or extended warranty. Most common items that we know that go out are 22kW OBC, Heater, Radiator Fans, etc. Each break down will cost significantly more than extended warranty cost just due to the labor cost alone for these repairs as hourly rates are set by dealers and start at $300/hour.

This is how I’m thinking about it and 8+ years out even if we have to replace the battery. I’m sure by that point it’ll be much cheaper to put a whole new battery in there. Whether it’s a third-party company or Porsche .I’m guessing it’ll be cheaper than a new car if we truly wanna keep the car.. otherwise like you said, we just rethink the relationship and buy a new one

I share the same experience.
My 22 TS CT has 75 kkm now and state of health is at a whopping 93,6 %.

Switching from a Tesla to a 2025 Porsche Taycan 4S can be an eye-opening experience, particularly when it comes to battery performance and range consistency. Many drivers who have made this transition report that the Taycan delivers a more predictable and confidence-inspiring electric driving experience.
One of the most noticeable differences lies in how range is estimated and delivered. Porsche tends to use more conservative projections for real-world driving conditions. As a result, Taycan owners often find that the vehicle’s displayed range closely aligns with what they actually achieve on the road. This consistency can create a stronger sense of trust in the vehicle’s battery management system.
Another key factor is Porsche’s advanced thermal management. The Taycan features a highly sophisticated liquid-cooling system designed to maintain optimal battery temperature during both spirited driving and high-speed charging. This engineering approach helps ensure stable performance over time, reducing power fluctuations and preserving battery health even under demanding conditions.
The Taycan’s 800-volt electrical architecture further enhances its battery performance. This higher-voltage system allows for faster and more sustained charging, lower heat generation, and more consistent power delivery. For drivers who value performance and reliability, these benefits can significantly improve the overall ownership experience.
Porsche’s philosophy with the Taycan has been to design a true sports car that happens to be electric. The focus is on repeatable performance, durability, and driving precision. By contrast, Tesla has historically emphasized efficiency, software innovation, and headline range figures. While Tesla continues to lead in areas such as charging infrastructure, user interface design, and over-the-air updates, some drivers feel that real-world range can vary more depending on driving style, weather conditions, and speed.
Ultimately, perceptions of battery performance often come down to expectations and priorities. For some drivers, the Taycan’s refined engineering and predictable range delivery create a more premium and reassuring experience. For others, Tesla’s technology ecosystem and efficiency advantages remain compelling.
As the electric vehicle market continues to evolve, these differing approaches highlight how manufacturers are shaping the future of performance, reliability, and user confidence in battery technology.

Coming from 10 y/ all Tesla models, I can relate to this statement.
Although PCM is a piece of compared to Tesla UI, anything else on my Taycan is superior.
I didn't miss Tesla for a second.
My wifes BMW iX20 though is another story.
She wants to go back to a Model Y 🫠

Battery wont outlive the car on 95% of j1.1 taycans - since they were manufactured with defects and they didn't replace batteries, instead they chose waiting for them to break down and only then replace modules. And after the initial 8 years of warranty, good luck, you pay out of pocket

These manufacturing defects are classified as ageing defects, which are not covered by the extended warranty. There is a reason they classified them like that, and unless you have it black on white from porsche that they will cover them, i would safely assume you're f*cked.

After the initial 8 years, when you need to pay 2.5k per module + tens of hours of porsche rate of work, the car is preatty much dead

 

[BjörnfromHamburg]

Well @chun, I know your Taycan bottle is almost empty, to me it's well filled and at least half full instead of half empty.
So I hold against your speculation with my own: by 2027/ 2028 Porsche will have a solution, not letting J1.1 standing in the rain without an umbrella.
If we are both here still by than, one owes the other a pack of Duracells.
