The Ultimate Egg
For the ultimate egg:
Cd: .19
I rather like it, as some of you may have noticed.

Fuel Efficient Vehicles Now! - 230 MPG Aptera
"...Aptera's space-age configuration and appearance result from pushing for an extremely low aerodynamic drag coefficient (Cd). The original Cd design goal was 0.06, radically lower than any production vehicle, even lower than the 0.075 Cd of the record-breaking Shell Eco Marathon PAC-Car II race vehicle. Aptera's web site now shows a Cd of 0.11, far short of the design goal but still astonishingly good. For comparison: Honda Insight Cd=0.25. Mercedes Benz's Bionic Car and General Motors EV-1 both have a Cd=0.19. Daihatsu UFE-III Cd=0.168. GM Precept Cd=0.163. Aerodynamics in Car Design shows that the Ford Probe IV achieved a Cd=0.152 and the Ford Probe V did even better with a Cd=0.137. Some of these comparison vehicles have very low aerodynamic drag while still looking more-or-less like conventional automobiles. Aptera certainly does not look like a conventional automobile...."

Now we have to ask, What is a car?
These record breakers are single surface vehicles at best. Try going up a driveway in them.
Second, let's talk crash tests. And headlights. And airbags. They are dream cars that inhabit the likes of Finky and friends.

Yup. Thats why the narrow vehicles are a nice idea when you are trying for very high efficiency. That Daihatsu doesn't look half-bad, and I like this VW prototype (CD=0.159) as well:

I wonder if those front wheel covers are very effective. I like them enough to want to see them on other cars but only if the CD numbers are significant enough to brag about.
What if they were on the new Tesla?
Seems like they've tried to hide the tailpipe.
Doesn't look like there is much of a trunk. Hopefully those rear seats fold down. I'd like to see a shot with the hatchback open. I suppose it is forthcoming.

Well as one of the first of the promised next-gen vehicles I have to say that my socks haven't been blown off.
Don't get me wrong, it's nice; it's functional; it's certainly a ground-breaking achievement for a company with the inertia of GM. I hope it draws plenty of plaudits and custom their way, even if they can't make a profit on this particular model.
Most of all I hope it gets many many drivers dabbling with home recharging and electric-only driving. Same with the "no tailpipe" rear end. These all help to bring key elements of BEV functionality and styling to a wider public.
Looking forward to reading the test drive reports.

I think a side profile comparison with the Prius is a good idea:
Hopefully the rear seat and trunk is of decent space given the changes they made to it.

It looks fine to me, but certainly not exciting.
Btw, Jalopnik seems to have better coverage of the Volt reveal than ABG.

Designwise I really like this as a "useful" design. I.e. it beats many other normal cars but not Aston Martin and the likes 
I hated the concept so in my eyes this is a LOT better. And on pictures it actually looks so good I wouldn't mind buying this. Of course we in Europe will probably have to settle for the Opel version, which usually means really really boring designwise. Oh well around 2010 we'll be able to compare the design and specs of the Model S, Volt, Opel XX and probably some more alternatives as well.
