What will EV's do to dealer repair center profits?

Maybe it's my English or I didn't read everything but I can't find this statement in there. All I can see there is this:
"Porsche says it does in order to improve efficiency, and also to help optimize both low-speed acceleration and top-end speed—pretty much exactly the benefits that auto supplier ZF claims of its new two-speed EV transmission."
"Porsche says it does in order to improve efficiency, and also to help optimize both low-speed acceleration and top-end speed—pretty much exactly the benefits that auto supplier ZF claims of its new two-speed EV transmission."
However (as you're indicating), that doesn't mean they designed Porsche's transmission with Porsche stamping their name on it. Porsche has already said: They 'didn't have one to pull off the shelf' as they would have liked, thus they 'had to build it, along with 800V and the PMSM of the Taycan' themselves. So, a simple inference, misinterpretation-it appears by Mr. Alex?

I would be very surprised if Porsche manufactures the transmission. More likely, a third party parts supplier (ZF?) takes over the manufacture and exclusively supplies to Porsche.

The two-speed transmission is made in-house by Porsche, not ZF.
According to Jalopnik:
Per Wired:
And from GreenCarReports:
According to Jalopnik:
The Transmissions
Of the two motors in the all-wheel drive Porsche Taycan, the one in the rear is more powerful. It makes 449 horsepower and 406 lb-ft of torque (or 450 lb-ft during launch with the Turbo S), and sits parallel to and aft of the axle centerline, sending power forward through a Porsche-designed and manufactured two-speed gearbox.That gearbox has a first gear ratio of roughly 16:1 and a second gear ratio of 8.05:1.

As the automakers crowding into this market look to differentiate the dozens of models they’re preparing to roll out, and as electric driving tech continues to evolve, Porsche is unlikely to be the only one making this move. The Taycan’s transmission is an in-house solution, and you can’t just grab a Formula E race car’s multispeed transmission and plop it in your daily driver. But auto industry supplier ZF is working on its own version of the two-speeder, which it’s looking to sell to any automaker that doesn’t want to choose between low-end torque and top speed glory.
Porsche says that it developed the gearbox for the Taycan on its own, internally. But perhaps in a vote of confidence for the market, suppliers are rolling out designs engineered for electric motors. ZF is bringing back its own clutchless 2-speed transmission for EVs earlier this year, and it notes that its unit could deliver a higher top speed and a five-percent improvement in highway efficiency.

Lots of home-grown tech (800v powertrain, electric motors and 2-speed transmission) to keep sorted out and presumably improved in response to competitors. I wonder how they are going to navigate the intellectual property issues that will inevitably arise. The future IP issues would seem to be a pretty compelling reason to partner with a third party parts supplier - when the relationship works, you get the benefit of technology improvement and don't have to navigate the IP challenges.
That said, there could be some reasons to build in-house: 1.) If Porsche-developed e-car technology finds its way into other offerings of the VW family, there could be a reason to do the manufacturing in-house (reduced cost of parts => higher margin on sale). 2.) Given VW's experience with the diesel emissions defeat disaster, there may be a desire to limit exposure to third party 'partners' self-serving actions, which could be another reason to manufacture in-house.

I am not trying to parse your links, but develop doesn't mean manufactured.

consumer reports pretty clearly indicates EV’s have fewer problems and are cheaper to own.

but they are just so much mechanically simpler and they don’t have the immense thermal challenges as ice
