30 mpg?

    By the way, the reason for using L/100km is it helps you make smarter car purchases. For example, in which case is it worth paying $2000 more for a fuel economy package?

    a) A car that gets 25km/L rather than 16.5 km/L

    b) A car that gets 7 km/L rather than 6 km/L

    Obviously in a) you'd take the deal, since you get 8.5 km/L more for the same $2000, right? For b), you only get one km/L more, that's a crappier choice.

    Ummm......your examples just used km/l, the way I and anyone over the age of 30 can relate to much better than l/100km.

    If some nerd wants to figure out vehicle costs on an annual basis using l/100km, they can go wild. For the rest of us, I know how far it is to my sisters house (15km), I know how much a litre is (just hold a bottle of oil in your hand). If I can get there on 1 litre in car A as opposed to car B that will only get 2/3 of the way there (10km/l) that is a much more vivid way to look at efficeincy than some marketing driven, accounting shell game mumbo jumbo.

    At any rate, my mileage has taken a dump too with this cold weather (-10, I know, boohoohoo from you flatlanders :)).

    Yep, no argument there - mpg and km/L are more concrete and easier to use in day-to-day decisions.

    I used km/L in my example cause it was a trick question - a) and b) options get you the exact same fuel savings - 2L per 100km.

    Calling L/100km an accounting shell game is unfair. I'd say it's the opposite - mpg distorts fuel economy numbers and makes it easier for car salesmen to:
    • upsell people on compact/hybrid cars whose high price isn't worth their fuel efficiency improvement ("WOW, 60mpg is way bigger than 40mpg!")
    • while making it easier to get people to ignore running costs when buying trucks ("oh, 11mpg vs. 9mpg, big deal")
    In that case, choosing the hybrid gains you 2L/100km, where choosing the gasoline (instead of diesel) pickup truck loses you nearly 5L/100km.

    One L/100km saved always means the same $$$ in your pocket. One mpg saved can mean anything, depending on how fuel efficient your car is already, for example: one more mpg on a moped = $, while one more mpg on a Sherman Tank = $$$$$$$$$$$$$$$$$.
