Although a concept variant is still an auto show or more away, Infiniti did release a new teaser sketch of its upcoming all-electric luxury four-door sedan. Not much appears changed from the original rendering that was first seen last September. As then, the automaker stated the Infiniti EV "will be a stylish, high performance five-seat luxury vehicle with zero emissions technology that befits the brand's promise of Inspired Performance." What has changed a bit is the anticipated arrival time of this super-green entry. According to the Frankfurt update, deliveries of the first production Infiniti EV models has now been slid back from 2013 to 2014.
