Did You Know? High MPG Doesn’t Equal Fuel Efficient Cars

1

EmptyLast week we posted a tidbit about the Top 10 Fuel Efficient Cars available today, and ranked them by their MPG. But today, we have a recommendation from the New York Times that says the MPG ranking on a vehicle is actually very misleading – fuel consumption actually changes drastically depending on the number of miles you drive. That’s why two Duke University business students think that American standards should follow suit with other countries and rank vehicles by gallons per mile (or liters per kilometer) – so that drivers can more accurately understand their car’s fuel efficiency. Because the relationship of fuel efficiency to MPG isn’t linear, but curvilinear (explanatory graph available here), the number of gallons of gas you burn over a long period of time will be far different than what your MPG will have you believe. By looking at the gallons you use per mile instead of miles you drive per gallon, you’ll actually have a better understanding of what to expect in the long run. With the high prices of gas these days, if you’re looking for a new vehicle, it may be something you want to keep in mind when you’re doing your research.
