Comment MPG is misleading! Use L / 100km instead ! (Score 1) 1141
I don't understand why anyone (except the car industry) would use MPG as a measurement by fuel efficiency. It's very misleading for most average (i.e. non math understanding) people.
Try this: which of those two options is a better fuel economy (better for the environment)?
1) Getting from 35 to 40 MPG
or
2) Getting from 15 to 17 MPG
You'd be tempted to say #1. 5 against 2, easy!
But, if you look at it from a L per 100km perspective, you get this:
1) is getting from 8.1 L/100km to 7.1 L/100km. (diff. of 1L)
2) is getting from 18.8 L/100km to 16.6 L/100km. (diff. of 2.2L)
So, #2 is actually a better fuel economy...
At the very least, MPG should be GPM if you -really- must go imperial....
