How Americans have saved 15 billion gallons of gas
The Globe and Mail
In 1923, the average vehicle managed 14 mpg and, for the next 50 years, fuel efficiency went downhill.
By 1973, the average was 11.9 mpg. Disappointing, but understandable. This was an era of cheap and plentiful oil. However, the industry’s gas-guzzling ways spun the image of a voracious and wasteful business.
While that image was grounded in fact 40 years ago, something different is true today. A recent study by the University of Michigan Transportation Research Institute shows fleet-wide fuel economy began to improve after 1973. By 1991, it hit 16.9 mpg, and while it then stalled for a decade and a half, fuel economy across the automotive fleet has taken a dramatic turn for the better since 2007.
