    Question about testing - Why does USA have such higher numbers?

    I understand the USA revised the way they test, to bring the official numbers closer to the reality of regular drivers. I'm wondering if the style of driving/geography/culture of the US leads to greater fuel consumption, or if it is just a matter of the test parameters. Are higher speed limits or greater urban congestion the cause, or is it just that the US has taken a more realistic approach while others have taken a more optimistic one?

    Put another way, would an average driver burn more gas going 100 000km in a Mirage in the US than that same average driver in New Zealand, the UK, or the Phillipines? Is this a testing error, or something different about the infrastructure of the different regions?

    Just curious as to your thoughts. Also noted that in some places the CVT is a big advantage, and in others it is not at all.

    Did you mean - why does the US have lower numbers? If you mean the official fuel economy ratings in MPG.

    It's because the US has revised its calculations and tests several times, with a major adjustment in 2008, to try to bring them in line with what the average driver was achieving. (Prior to that, its numbers were very similar to Canada's (ie. higher fuel economy ratings). Canada is about to revise its tests/calculations as well.

    Many of the countries where the Mirage was first sold use fuel economy ratings based on European NEDC tests, which are also understood to be too optimistic for the average driver to achieve -- further from reality than the U.S. rankings.

    OK, thanks. I meant higher, as I was thinking L/100km, but lower in terms of mpg. Those yanks, keeping the metric system down . . . I don't know how they do it!

    So do you think some of the other countries in Europe and Asia don't get near the estimates in real-world driving either?

    I've heard from many europeans that NEDC is unrealistic, and that is coming from hypermilers haha.

    The Euro/NEDC numbers are even more optimistic than the current Canadian NRCAN ones! Very few "typical" drivers will achieve them.
