Blume's comments clear up uncertainty about 911 electrification plans. The company had indicated it was exploring a plug-in hybrid version but said this spring it had dropped the option in part because battery weight would make performance unacceptable.

Porsche has prepared the next-generation 911's platform to accommodate the battery system for the plug-in hybrid, Blume said. And waiting until the midcycle update will allow Porsche to get more power and range from the batteries, he said.

I just wanted to make sure I was getting the term "Plug-in hybrid" right.

Plug-in hybrid
https://en.wikipedia.org/wiki/Plug-in_hybrid

A plug-in hybrid electric vehicle (PHEV) is a hybrid electric vehicle that uses rechargeable batteries, or another energy storage device, that can be recharged by plugging it in to an external source of electric power as well as an on-board internal combustion engine and generator....................

This distinguishes PHEVs from regular hybrid cars mass marketed today, which do not use any electricity from the grid...................

The Institute of Electrical and Electronics Engineers (IEEE) defines PHEVs similarly, but also requires that the hybrid electric vehicle be able to drive at least ten miles (16 km) in all-electric mode (PHEV-10; PHEV16km), while consuming no gasoline or diesel fuel.[27]...................

Invention and early interest

The Lohner-Porsche Mixte Hybrid, produced as early as 1899, was the first hybrid electric car.[33][34] Early hybrids could be charged from an external source before operation.

If the end is leading you back where you started, then yes, the end is near.
