Gas Mileage and My Prius
I am the guy with an NRA sticker on the back of my Prius. Some people say I’m conflicted, but I see no problem with frugality.
But I’m paying the “hybrid premium”, you say? Let’s examine that common objection to the Prius.
My daily commute is 90 miles round trip, about 20,000 miles a year just back and forth to work. My Prius has 125,000 miles on it, and I’ll probably trade it in sometime in the next two years. There are at least two ways to approach the cost of driving; one is to buy a more economical car, even if it doesn’t eke out the 51 miles per gallon I get with my Prius. The other is to calculate the total cost of ownership. So I sat down and did some calculations, with just the vehicle purchase price and gas cost in mind (both cars can be expected to have about the same cost of maintenance over 150,000 miles).
The 2012 Ford Focus looks to be a great economy car. It is expected to cost in the $18,000 range, and should get somewhere around 28 MPG. Great mileage. I calculated the total cost of driving 150,000 miles — my average mileage when I trade a car in — at a cost of $3.50 a gallon. The Focus would use 5,357 gallons of gas at a cost of $18,749. That makes the total cost, car purchase plus gasoline, at $36,749.
The 2011 Toyota Prius will be the same as this year’s model, and pricing is expected to be similar at $23,000. At 51 MPG I’m getting with my current Prius, it will burn 2,941 gallons of gas over its 150,000 mile life. Applying that $3.50 cost shows the Prius total gas cost to be $10,294. Add that to the purchase cost of the car, and the Prius costs $33,294 over its life.
The more expensive Prius ends up costing less … $3,455 less … than the less expensive Focus.
Americans don’t buy cars just with personal economics in mind; the ride, comfort, handling and status of a car all figure into the equation. So cost alone won’t be the determining factor.
