MPG or MPD, Which is the True Definition of Fuel Economy?
I read an article yesterday that said the Toyota Prius was the most fuel efficient car in the US. One of my personal objectives is to get better fuel economy than the hybrids. The Toyota Prius gets, according to the EPA, 47 mpg. Our average going to Phoenix and returning was 47 mpg in a Chevrolet Aveo. All I need to do now is get one more mpg and my first objective will be reached. My ultimate objective is 60 mpg for under $200.00. Time will tell.
A Toyota Prius costs about $24,000.00 according to the Internet prices I found. That’s three times what we paid for our Chevrolet Aveo. And this is where MPD begins to come into play. Don’t get me wrong, I’m not knocking Toyota or any other Japanese car. One of my automotive businesses was named Japanese Automotive and all we sold parts for and serviced was cars from Japan.
For years, the measure for fuel economy has been MPG. Times have changed for some of us and overall economy is more important than MPG. MPD, or miles per dollar, is the new benchmark for cost per mile . If you want a first hand, real time look at where your money goes after it disappears into the black hole called your fuel tank, next time you fill-up don’t put it on your credit card, use cash.
Next, you need to sit down and figure out how much you paid down and, how much you pay per month and calculate the total months you’ll pay on the loan. Then, and this is X the unknown, try to calculate how much you’ll lose in depreciation. That’s the only true gauge of how much your car will cost you when using the MPD formula.
Miles per gallon never really was a true determinant of what it cost to drive your car, it was only a head game, and still is. Very few ads even use it, mostly they tap into our subconscious and play the Madison Avenue hype game. Leagues, stones and pecks have lost their meaning in the world of measurements, and so has mpg.
How do you figure basic MPD? Simple, take mpg and divide it by the price of fuel. You will find the result is directly related to dollars, yen or pounds. When gas was a buck a gallon, not all that long ago and BGB (before George Bush), it cost a dollar to go twenty miles if you got 20 miles per gallon. Now, gas costs three times that much, most cars don’t get any better fuel economy than they used to and you’re going 6.6 miles for a buck. All of which means your paying about $10.00 per hour to drive your car, if you get 20 miles per gallon.
If you have a heavy or twitchy foot, and get ten mpg, going to the store will probably cost you as much as the groceries you buy. If you figure all the hidden costs in true MPD, it will be a lot more than the bread and butter or, hopefully, veggies and healthful food.
The Toyota Prius only goes 15.33 miles on a dollar, less if you figure everything. If you drive something that gets 12 mpg, you’ll go 4.00 miles per dollar and that may be a whole lot further than you’ll go for a buck if you drive like most people. Last trip to town, a car passed me with black smoke rolling out the tailpipe and I was doing the speed limit. The car disappeared ahead, but not for long. A little farther down the road the car and driver were parked on the shoulder with a state police car and red lights sitting behind. Figuring the rise in insurance and the price of the ticket, you can bet that was a costly MPD trip. Plus, there’s no doubt in my mind that I got to town before the other driver.
Using the old mpg measurement, if I can get 60 mpg, I’ll be back driving 20 miles on a buck.
