| Post subject: | MPG versus GPC |
Think about this: For every 100 miles driven, if I choose a vehicle that gets 15 mpg over one that gets 14 mpg, I would save the same amount of fuel as someone who chooses a vehicle that gets 50 mpg over one that gets 40 mpg. Obviously, the 15 mpg vehicle would use more fuel than the 50 mpg vehicle, that's not the point. It would be more useful for consumers to see GPC (Gallons per 100 miles)on the sticker instead of MPG especially as we are in an era where cars are achieving 40, 45 ,50, even 60 mpg. So in our slanted world those who can get 20 or 22 mpg are really saving fuel over ones that are only achieving 16 or 17 mpg. Say you tweaked your slant for economy and increased from 16 mpg to 22 mpg. If you decided you needed to park the 22 mpg slant for a more modern, more efficient car and you wanted to save the same amount of fuel you saved in your effort to get from 16 mpg to 22 mpg, then you would have to buy a car that achieves almost 38 mpg, an increase of 16 mpg. I didn't come with this idea, I read it in a car mag. I couldn't see it until I did some conversions and graphed it out. Comments? |
