I believe I read where they are redesigning the hood and front intake (again). Apparently they are at 80+ mpg, but not quite 84 and the redesign is an attempt to hit that magic number of 84. Hell anything over 70 is OK with me. Every year they delay is a lot of extra money I'm paying on gas. Since the majority of my driving is around town where super slippery aerodynamics don't count anyway I'm considering going with the earlier style open fenders with nice mag wheels and wide tires for the 'hot rod' look. Buy the car in black then drive it straight to a custom paint shop for a flame job. Oooo-yeah baby!
The Lotus Elise was clever in that when it was at speed it made a little downforce, like 30-50 lbs, hence little drag.
