Memo to Renault: Everyone at car shows stops caring after your second electric car. Example? Your Renault Kangoo ZE. Yes, we know ya worked hard on them all, but save some for later. Also, turn on the lights.

In preparation for expanding their model lineup with a range of electric vehicles in 2011, Renault is showing four electric car concepts at Frankfurt. Two could be production-intent and the smallest has square wheels. Yeah, that one won't make it.
