That's a comprehensive list ! Not sure what the qualifications for entry are, other than an EV with a plug, but I can think of a couple of EV supercars that I think should be added to the list. And if we're listing Kangoos the the Mia and Smith Electric vehicles deserve a mention.
RIMAC CONCEPT 1
1100 BHP fairly amazing sounding Rimac 1. A Quad motor, 91kwh EV with Veyron humbling performance apparently. Yours for about £600k. Deliveries set to start in 2015.

LIGHTNING GT
Handsome British EV GT, but spec, prices, delivery have been changing for numerous years, but there's at least two road legal ones out there ..

MIA EV
Central driving position, 3 rear seats, side sliding doors! I tried one out in London 2011, but not sure what's happened to it since.

SMITH ELECTRIC
Range of heavy duty delivery vans and trucks been selling in the UK for many years now. Already in use in London for Fedex and UPS and others. Tax and congestion exempt etc. 70-100 mile delivery range. They have a plug. Do they qualify ??!?!
