Idonunderschtan. Aluminum foil isn't all that good for reflecting various bemf and accelerated particals. Lead foil or steel sheet perhaps, best would be foil made from depleted fissionables.

Must be a cost/availability decision

The VW Gol.....................I never hear of the Gol before.

https://engineeringworkarounds.blogs...different.html
Quote:
The same boxer engines also served the earlier versions of the Gol, such as this '80 model which still resorted to the 1.3L engine. Rumors quote this to have been an attempt from Volkswagen to get rid of a stock of engines which were refused by export markets. The replacement for the 1.6L engine on the following year increased the performance to levels deemed more acceptable by the overwhelming majority of Brazilian customers, and the "BX" lasted until '86 when subsequent versions of the Gol were by then all fitted with water-cooled engines. A key difference to the Brasília is the fact that the Gol had the engine mounted upfront and with front-wheel drive.
I assume it's like other VW's of that era about .32 Cd.

The first generation Scirocco remained relatively unchanged during its production until 1981. Volkswagen sold 504,200 units of the Mk1 Scirocco.
1982 paved the way for a new generation Scirocco (Mk2). This more rounded, slightly longer Scirocco was designed internally by Volkswagens styling studio. Based on the same platform as the original Scirocco, the new body allowed drag coefficient to be reduced from 0.42 to 0.38. A 1.7 L (1,717 cc) engine was fitted that produced 74 hp.
The .32 Cd I picked up earlier must have been for some of the later VW cars.

Not sure where to put this one, exposed wheels should kill the aero, right?

Gol is similar to my Dasher.

P-38 belly tanks are in short supply. My solution:



Half the wheels are on a tandem bogey to improve the aerodynamics.

My grandmother by the mother's side still has an aunt from my great-grandmother's side who considers the Gol the best car ever, even though nowadays it's much different from the early days...

Its design is often mentioned to be inspired by the Scirocco.

Thanks, I could not remember that name the other day.

Looked up VW Fox instead.

Remember the Renault Reliance?

Smart looking car for it's day, worse Cd than the Dasher/Gol I would imagine.

Thanks for the laugh Frank Lee.

The Fox was based exactly on the Gol, even though air-cooled versions are often reported to have been available only for the Gol and the Saveiro. BTW the BX floorpan of the Gol and itsderivatives is also widely reported to be a simplified version of the Passat/Dasher B1

I have only seen 4-door ones, which used to be popular in Argentina.
