Problem is, that the price of fuel is so cheap compared to the price of a new car. (even in expensive fuel places like the UK, at currently £1.40 per litre) As a consumer spending $30 000 on a car that gets 35mpg vs $35 000 on a car getting 70mpg, which one is the average consumer going to buy? Where is the ROI for development vs adding electronics like cruise control, auto-start stop, ipod connectivity etc.
Consumers want larger and larger cars with more electronics and cupholders. I don't think in the lifetime of the pure ICE we will see much of a shift towards very low drag and low frontal area.
The trend is towards larger cars that are more aerodynamic, but due to greater frontal area, are no more aerodynamic than the equivalent car years ago. Isn't the original golf similar in CdA to the new golfs?
