Speaking from a European perspective, I think classic minivans are dead. There are just a handful of minivans left on the market, and I doubt any of them will be electrified.
People who used to buy minivans now have 3 options:
- if you don't need to transport more than 5 people, you can get an SUV. There are lots of electric options.
- if you want to transport 5-7 people and want a lot of cargo space, you can get what wikipedia calls a "leisure activity vehicle" (VW Caddy, Renault Kangoo, Mercedes Citan). A new electric Kangoo with longer range is coming, and there's the Mercedes EQT concept based on it which is as close to an electric minivan as you'll get.
- If you want an even bigger car that can transport up to 8 people there's the EQV from Mercedes.
