Highway fuel economy is for suckers
So, the Ford Focus is a better deal than the Toyota Prius, and GM offers more vehicles that achieve 30 mpg or more than any other automaker. Of course, ONLY (and maybe not even then) based upon perfect world highway fuel economy.
So, what percentage of your commute is a cruise-controlled 55 - 65 mpg on a flat surface without any wind resistance?
Most people, even in small towns, stop at a few stop signs or red lights, conditions that reduce fuel economy significantly. Suddenly, 30 mpg is more like 20-25 mpg, or even worse, depending on how many stop lights you actually hit. Then there is the kind of congestion that you find in large cities like LA and Chicago. In such conditions, the Toyota Prius has been demonstrated to average almost 60 mpg. In tough urban congestion the Focus might not even achieve 20 mpg.
Yet, according to transportation studies, congestion is increasing and it's going to increase significantly in the future. So, is highway fuel economy even relevant anymore? Even worse, isn't marketing highway fuel economy deceptive?
