First off, we hate renderings in isometric view with perspective turned off. It just looks fugly.
As soon as the whole thing isn't warped by the magic of computers it will look pretty good though. This is one of the few times we'd be happy to see things get a bit toned down for a production version.
The Emerg-E will be powered by an electric motor with a range extending engine. Given Lotus's new range extending engine that is getting sold to other auto-makers and the rather Evora-ish profile and proportions of the Emerg-E, we wouldn't be surprised to find that the British Malaysian sportscar manufacturer had something to do with this. Lotus is known for licensing platforms.
We're just wondering how Infinity plans to make that contoured rear window.
