Definitely an interesting concept and makes perfect sense (to me) to use off the shelf components. But I suspect the large manufacturers would rather differentiate than standardise to emphasise their unique selling point.
(In the applications section there is a nice side view, line drawing of a pickup body that looks like a VW Bay Window pickup - got me wondering if it would be possible to drop a VW camper body onto one of these. Could be an interesting project for the future.)
As with most electric cars the range leaves me cold (like cycling in this weather
) as I wouldn't want to entertain having to have two cars, one for local use and another for long range...
