That's about how much I pay to enjoy "spirited" driving rather than hypermile. I recently went to Austin and back trying hypermiling techniques. I watched my revs, made sure I wasn't getting over 4000 rpm for too long, no mad dashes from stoplights, timed stoplights, etc... I averaged about 27 mpg according to my car's little computer. Now compare that to my previous mpg of 23 mpg (city and highway mixed). Now I ran that through my long forgotten math (hey kiddos, this is where math is fun), you should appreciate math. 400 miles back and forth to Austin. 27 mpg with hypermiling = 14.8 gallons of gas used 23 mpg without hypermiling = 17.4 gallons of gas used difference = 2.6 gallons or $7.80 (cost of gas held at $3.00 gallon, not the current $2.59 I recently paid for Supreme) (divide by 400 miles) = $0.019 savings per mile by hypermiling. In the course of a year 24,000 miles = $468.00 or $39.00 per month Now if you want to compare a full size pickup truck (17 mpg) to a Prius (40 mpg). The difference is about 10 cents a mile or over the course of years driving (24,000), $2400.00, or $200 per month What's the point of this? To demonstrate that while hypermiling saves gas and money, it's not enough for me to lay off the accelerator and enjoy the wonders of engineering and physics. As for my truck v. prius example, the difference is probably greater than my example, but I don't care, I'll never buy a Prius. Not to be anti-tree hugger or anything (hey! I traded in my Expedition for a BMW station wagon to save gas and the environment) I have my limits. Would some of you wear your parents's clothes to save money? Would you just eat tofu and greens to save money and stay healthy? Would you just drink tap water rather than diet coke? Would you have just any mp3 player rather than an IPOD? Would you rather get on the Internet with dialup vs. cable or dsl? I think you get my point. |
