Saved $360 this month

May 6th, 2012 · 2 Comments

At the rist of completely boring everyone with more talk of my Volt, here’s a cost comparison I have worked out with my previous car (Acura MDX) and the prototypical gas miser, the Toyota Prius.

Comparing the cost to drive my Volt (at 2.5 cents/mile) and the MDX (25 cents/mile), I have saved $360 this month driving 1600 miles. At this rate, I would save $4320 in a year. Compared to a Prius, at about 45 MPG on regular at about $3.75, I have saved about $93 for the month.

But I’ve been driving 40 miles to see Mom in the hospital almost every day. Past history shows I actually drive on average about 1000 miles/month. In addition, summer electric rates are higher, increasing my costs in the Volt to about 3.9 cents/mile. Averaged over a year, it comes to about 3.3 cents/mile.

Here are tables showing the savings this month, and then in a typical month.

 Price of Energy   Miles/Month   Cost/Month   Cost/Year 
Volt $.025/mile 1600 $40 $480
MDX $4.00/Gal 1600 $400 $4,800
Prius $3.75/Gal 1600 $133 $1,600

 Price of Energy   Miles/Month   Cost/Month   Cost/Year 
Volt $.033/mile 1000 $32 $390
MDX $4.00/Gal 1000 $250 $3,000
Prius $3.75/Gal 1000 $83 $1,000

    What’s the difference in the Price of Energy between the Prius and Volt? It is because the Prius uses a lot of gas in it’s normal driving? I would think the MDX would be a lot higher than the Prius.

    The Prius uses regular, which is selling for around $3.75/gallon, while the MDX used premium at about $4.00.

    Mileage is reflected in the Cost/Month and Cost/Year (45 MPG for Prius, 16 for MDX).
