SIM-LEI EV gets a video walk-through: shaped like a fish, has a big screen (video)

Zero to 100km/h (62mph) in 4.8 seconds, with maximum speed of 150km/h (93mph), range of 333km (207 miles).

So what's the catch?  Tastes vary, but this is ugly.  First assumption would be that this is for aerodynamic purposes.  In the articles linked below, a "tiny coefficient of 0.91" is quoted.  Update 01 January 2011: "tiny coefficient of 0.91" should have been a tiny coefficient of drag of 0.19, which is actually tiny.  To put this in perspective, the coefficient of drag (Cd) of some other energy efficient cars:

0.28 Chevy Volt
0.32 Honda Insight (2010)

Toyota claims a Cd of 0.25 for its Prius, but other manufacturers claim it is more like 0.30 .
