.36 seems more realistic.

yeah , .36 is still amazingly good for that era..

The model 87 was suposedly a little worse than the 77a , but ime wondering if the wiki figure was in error.
Has anyone found a reliable figure for the 77 apart from wiki ??

This model vw keeps coming into my mind for potential FE mod car....



..but with a modern efi engine.
Best part is that it allows almost any body (aero) modification legally.

Unfortunately, that VW type 3 looks to have about the worst possible rear rake. According to Barnard, the highest drag is associated with rake angles around 30 degrees (from horizontal).

If the wacky Cd figure came from wikipedia, I wouldn't be surprised.

I corrected a wrong entry there for the Cd of the Audi A2, which someone had listed as .24. (Its lowest model was .25 - info I got from Audi's corporate site. Same Cd as the Insight).

I still like the idea of turning a Plymouth Breeze, Dodge Stratus, Chysler Cirrus, into a more economical car. They start off with real good c/d .31. I'm thinking a little work woudl drop the cd nicely

.01 Lowered 1-2 inches
.005 Front Dam smoothened and smaller grilll opening
.01 Smooth Underbody
.005 Partailly covered rear wheels and smooth hubcaps
.01 Mirror removal

Capow! if you could get these good of numbers, It'd drop to around .27! Now you just have to deal with the poopy motor.


My parents own one of these cars which i "MIGHT" get for graduation, otherwise they're very cheap, cuz well they're really nothing special.

Thumbs up

Check out this vehicle:
Attachment 76

Attachment 77

It's a Renault Vesta 2 research vehicle and it has a Cd of only 0.186! Note how the back end is totally sliced off. Sources say that it used 1.94 litres/100km (121 US miles per gallon) for 500km trip with an average speed of 100km/h!

?A prototype named Renault Vesta II is with 3.5 l/100 km expenditure-comes.?

from what I read that 1 point whatever per hundred was a one off freak figure., and 3.5 was its long term figure. -- which is nothing truly amazing.

3.5 = 67mpg , so 1.9 = 110mpg (roughly)
