Turns out the unit is Aptiv and is UFS based. So no low hanging upgrade fruits this time and kudos to Porsche.
In other words, it’s already a fast storage. PCM speed is just software bloat, probably layers and layers of abstraction.

I'm intrigued by this thread as I don't find the PCM in my car to be particularly slow to respond...

Do people who find their PCM slow/laggy have early model Taycans? - I have a 2023 car with the newer look interface (more colours, etc.). Does anyone know if the hardware was updated when the new look interface was introduced? - would that have been for the 2023 model year?

I don't understand these posts at all? I have a 2024 GTS and i have never had an issue with the PCM or car play etc. Its great. Far superior to the C8 RS6 i had previously.

There are small hardware differences between model years; and different hardware IDs related to PCM, but it's unlikely that there is an actual difference in processing power / speeds, and rather just different IDs related to manufacturing year / batch.

It's more about what your expectations also are.

When I get in the car, I want to press maps and looks for an address immediately. And that is not possible in the taycan; because the map takes 20-30 seconds to open after a long parking; then you put the address and it's another 20-40 seconds for it to find it; then you press it and it's another 20-40 seconds for it to start navigation to it. Same for spotify.

I want to mention that after short parking periods, this issue does not exist, as probably the car does not shut off 100%; while after longer period of parking it probably is off completely.

And it also depends what you compare it to? Should I not compare it to a tesla? To a mercedes? To a chinese car? To a phone? It is an infotainment system after all, and I think all of these comparisons are fair; seeing the price tag of a taycan.

And I don't think I am the only one with this issue. I look at my phone, it's instant and snappy, I open the door to my quarter million car, and bam... i have to spend 30 seconds per click in maps until the system "warms up".

Far superior to the C8 RS6 i had previously.
But should we compare the taycan to older ICE cars, or to other premium EVs? Tesla, Rivian, BYD, Merceds, Hyundai, KIA, BMW, Polestar etc; all of which have better software and much snappier infotainment?

Hmmmm.... My 2023 £115k RS6 is exactly the car I want to compare to. I want my car to feel like a tool, not a Chinese toy.

If you think an iPad in the middle is the future I'd have to disagree. I love the way the Taycan feels familiar to high end ICE cars... Hell, it even has elements of 911!

Tesla can keep their fart buttons. I couldn't care less!

Have you ever owned a Tesla? I'm going to go out on a limb and say no. Every manufacturer has their advantages and disadvantages. I switched from a decade of Teslas back to Porsche, so obviously I believed Porsche had a net advantage, but don't kid yourself, Tesla does a lot of things way better than Porsche. I could tell you about Tesla's user experience, etc, but for the sake of brevity lets compare two similar experiences, dealing with the same issue - battery defect can cause it to short out and potentially catch on file:
  1. Tesla solution: deploy a software update over the air within a couple of weeks, which tests every Tesla worldwide, affected cars are capped to lower SoC and informed they need a battery swap if still under warranty (most affected cars were 8 year, unlimited mileage). Battery swap takes a couple of days in the shop.
  2. Porsche solution: issue a recall in some countries only, take a couple of months to notify owners, have people book an appointment months later to install an update which may limit the SoC to 80% (we don't know yet, Porsche hasn't released the actual software to dealers yet), then if software says the battery is bad, place your Taycan at the shop for few months (3 months seems like the median waiting for battery diagnostics and eventual module replacement)
Which one would you rather experience?

You make an interesting point about how the companies treat problems but that's not what's being discussed here.

How do the products compare? - Taycan vs Model-S?

Taycan has a battery recall every other week

Model-s hasn't had a battery recall in about 5 years if I am not wrong, and a battery recall that requires to be in the shop to fix some component even more.

Taycan can be driven 3-6 months a year, since 3-6 months is in the service getting battery recalls done; tesla can be driven 12 months a year.

Taycan can't do OTA updates to its software, to fix small issues even. Tesla can.

Taycan costs 2-3x the amount a Tesla costs, but offers less than half of the functionality of a Tesla.

That's how they compare as products :)



Why do you think Taycan sales plummeted? EV means more than just a different drive train. People expect more. People expect competent software, a car truly for the future. By the way, these are the words of VW group CEO, not mine. :) It is the reason he gave for bad sales in china, the market they choose to focus on, where cars sell horribly because of bad software and bad service :)

Porsche used to mean great service for your premium car. Now it means 3-6 months in service out of 12 for your premium car :)

It's true Taycans, particularly early ones, have had issues but I'd suggest people buy a Porsche for the driving experience, the badge and how it makes them feel. If people just wanted a car they'd buy a Kia.

You might also be forgiven for thinking all Taycans have had big problems and been off the road for extended periods, especially reading posts on this forum where you only hear from people who have problems, but that's not true.

Telsa may have got lots of things right but I'd far rather have a Porsche sitting outside my house.

Product is not just what you get on delivery day. It includes the entire customer ownership experience, at least to me. Would you judge whether or not to buy another Fisker Ocean again based on only what you got in delivery date?

I personally prefer the experience of a car I can drive, over an experience of owning a better car stuck in the shop, or waiting for parts on a recall. But I get that some people derive their pleasure from simply owning a car, even if they can't drive it. To each their own.

Yes, you'd rather have a piece of nonfunctional metal outside your garage :) Must be nice to afford a car that you can't drive. Same mentality as having a 18 year old girlfriend when you're 92; having something that you can't actually "use", eh? :))

Well, most people like to use the things they have.

Until the taycan has a v8 or a v12 in it, it will be compared to other EVs. And when compared to other EVs, it is an embarrassment, and it's not me saying it, it's the market. The only thing it does better than other EVs is driving dynamics. Infotaiment? Shite. Space? Shite. Battery technology? Shite. Battery enclosure? Shite. Service? Shite. Everything that's free in other EVs, is a paid option in a taycan, so not great on that front either.

The reality is the market chooses ipad on wheels over driving dynamics ;) So unless Porsche learns to offer both, they will forever be at the bottom of the food chain in terms of car market share.

Right now Porsche can't even offer what they were historically known for: service & quality. They have been making the best brakes for decades, but on the taycan they didn't bother testing the brakes in all hight configuration. And now people are told to drive with the risk of brake failure, because "great service". Great quality huh?

Most maybe, but not all. How else do you explain 5+ year old Porsches with less than 1,000 miles on the odometer? Perhaps, some people's definition of "use" of the Porsche is different than "drive"? Speculative investment, garage decoration, status symbol, something to show off on the driveway to the neighbors, etc?
