Power from engines is not linear. Volumetric efficiency (engines are air pumps!) is not linear.
The efficiency of a transmission is not linear.
The amount of energy required to travel the same distance is not linear to speed, at all.
Go 1 MPH somewhere, you'll have terrible gas mileage. This is precisely the exact opposite of what you're describing.

But their efficiency can't improve with v^-3, so air friction wins. Just check the consumer reports on cars' fuel efficiency. Optimum efficiency is around 80km/h for most cars.
