Extended Range EVs

Folks who have been following the transition from ICE engines to battery electrics know that this was a new (and popular) concept about 10 years ago. GM had a modicum of success here with the Chevy Volt and various near-identical models they were selling in the UK, Europe, and Australia, until Tesla came along with enough range to render the subject moot.
This isn’t simply an old article; I actually don’t have a guess as to what’s going on here. It’s like seeing an announcement that reads: “Hyundai Reports: Fuel Injection Systems May Soon Replace Carburetors.”
