Nissan has unveiled a two-seater electric city car concept named the New Mobility Concept or NMC for short. If it reminds you of a recently seen model, then you've got a good eye, because the NMC is nothing more than a rebagded version of the Renault Twizy, which made its world premiere at the Paris Motor Show last month.

Although Nissan didn't mention the Cube in its press release on the new Townpod EV concept, it's not hard to make the connection between the two cars.
