Diesel REX vans would be a MASSIVE hit if a company would just decide to start making them.

The #1 reason for (european) companies not buying full EV vans is range, they need to drive a LOT during the day.

REX would solve that with minimal emissions. And depending on the battery size, they could drive on full EV in city centres and only allow the REX to charge the battery during longer drives.

The BMW i3 REX is a fantastic car, if you can find one, buy it.

They are the cheapest hybrid out there currently, at least here in the USA. I think the average American prefers a larger vehicle.

I think a Diesel indirect injection REX would be awesome. It could burn vegetable oil, which is more viscous, but indirect injection doesn't need to atomize the fuel as much.
