It's been confirmed that the Taycan will get rear wheel steering. Or as Porsche often calls it, rear axle steering.

I've felt how well this works in a 911 Turbo S and have to think it'll be amazingly good when paired with real-time torque application at each individual wheel!!!

"Thanks to the rear-axle steering, everyday usability and performance have both been equally increased.
At speeds up to 50 km/h, the system steers the rear wheels in the opposite direction to that of the front wheels. This has the virtual effect of shortening the wheelbase. The turning circle is reduced, steering into corners becomes much more dynamic and parking is noticeably easier.
At speeds above 80 km/h, the system steers the rear wheels in the same direction as that of the front wheels. The result is a virtual extension of the wheelbase and increased stability, for example when performing high-speed manoeuvres on the motorway.
Between 50 and 80 km/h, the steering direction is constantly changing depending on the driving conditions. Thanks to the excellent stabilising properties of the rear-axle steering, it has also been possible to make the steering ratio on the front axle more direct around the central position. The advantage here is greater agility without losing stability at higher speeds."

Here are two videos that help. One direct from Porsche.


And here's a more generic version.
