Why does a 1935 Tatra have a lower Cd than any production car today?

Then there were the Alfa Romeo "BAT" cars, for "Berlinetta Aerodinamica Tecnica."

Here is the 1954 BAT 7 with a Cd of 0.19

I have a model of the BAT 7 on my desk. I wish I could find an Alfa Spyder with the "long" hard top. (very close to the roofline of the BAT 7)

back in the 30-40 the main design of cars was "streamlining" big curved hoods, fenders, rearends.

look at the cars from the 10-early 30's most of em had flat square radiators, flat square bodys, square/arched hoods, and not very aerodynamic.

now the mid 30-40 was all about slopes, curves and sleekness.

50's was fins
60's was all about power
70's was big fancy cars
80's was econocars
90's was econocars/midsize cars
late 90's-2000's suv's and huge trucks...
