Well, here is a video link. First I want to say I am a Mechanical Eng - but is it just me or does it seem like a lot of clunking and RPM just to go 20 mph? also, I find it hard to believe the var-speed tranny is 94 to 97% efficient as they claim in the "our technology" link ( I think we have some theoretical calculations deriving these numbers). I guess it would be ok if you needed a tranny on an EV, I find it hard to believe it is more efficient than at direct drive and a zilla. Just the maintenance on the moving parts would be a bummer (maybe that is why some car companies like it?).

This statement, "'In order to get a patent on something like this, we had to
make the government happy about the road tax,' Luedtke said," sets off my BS
detector. Last I heard, that wasn't a qualification for granting a patent.

Also, it might be the photo, but I think those battery interconnects look a
little light for a Caravan at 96 volts.

I'm not sure that pieces like this in the media do much for the EV cause.
