Inquiring minds want to know.

Way back when Tesla was developing the first few Roadsters, they tried using two-speed transmissions. Could not keep them from failing. Fortunately some higher power IGBTs, fancy power transistors, became available. So they were able to hit their performance goals with a single-speed gearbox. It will be fun to see if Porsche will have better luck.

Not luck, design

The same happens to if the Taycan has tougher gears or the computer slacks off the power to the motor at the right time before shifting gears then the torque will be within the gearing specs.
Any other suggestions on how it can be done?

I think they can do it. If you switch gears without watching the power sent to the motor then the torque will rip into the gears old design gear boxes. See what happened here for example: https://www.youtube.com/watch?v=ZAVdH91ZJq4

Also, we have come a long way in transmission designs since the days of the Tesla Roadster.

But think of an off road vehicle. No need for locking diffs, for locking transfer cases. It's all electronic. Slip detected at one wheel? Just don't give it power.
