Well, 3 decades actually starting in the 1970s. The NSU Ro80 started the trend at the end of the 1960s but was let down by poor engine choices. Citroen started with the DS and then the CX in the 1950s-70s. A limitation in this is the technology available to put these cars together.

Not really, a lot of cars from that period were designed with Aero in mind - Audi 100/200, 80, 90, Citroen CX, Renault 25, SAAB 9000, Mercedes W124 etc. All of these got close to, if not better than the GM cars. The Calibra was the most aerodynamic production car at the time, and it was a volume product. I just focussed on GM and Ford.

But none of those not a single one of them have what I would call extreme focus on Aero, which is now SLOWLY but surely creeping into mainstream, with cars like your Prius etc and "efforts" now finally seen by mainstream to incorporate things like kammbacks into the car designs and sealing up gaps in the car body.

The Insignia has a Cd of 0.27 according to your list, the Prius is 0.26. The Prius is supposedly state of the art in terms of economic design, the Insignia is a mid-range GM 4-door car. The Sierra definitely was extreme at the time.

Take the NEWEST models you have posted, and take their general overall design, and I believe you will see that they have VERY LITTLE in common with the cars they "replaced" from the previous decades and have a lot more in common from the rather "early age" of the car as such. 30-40-50's had a lot more rounder and "aero" vehicles than the following decades. So as my thread topic states "In 60 years.." the mainstream auto industry have been at a fairly stand still when it comes to AERO improvements when comparing to other improvements we've seen in the automotive industry!

You would need to give me examples of how they are the same as much earlier periods - maybe this is what I'm missing ?

I think there has to be a difference between production cars and prototypes of some kind - without examples I'm wondering what those might be. Currently people have fuel record prototypes getting extreme figures but they have no practical value outside those competitions.

I love geeking out
