The electric three-wheeler in this French blog is maybe just over the microcar size limit - or maybe it's just the (Saxo?) doors that make me think that:

hello all
i'm the one behind that "thing"
the doors actually come from a 1998 5 doors clio.
I don't think it can be considered as a micro car, due to the boot and its size. It's larger than a toyota aygo.
then come the engine, it produce 35 hp peak, for a micro car, it will have really good acceleration.
if your have any question, fell free to ask.
I'll create a post on its building if your are interested
