We all know that US EPA figures are much easier to beat than European NEDC figures.
This frustrates those of us who own cars that were never EPA rated.
EG: Honda Fit/Jazz 1.5 CVT 36mpg (6.5l/100km) combined. NEDC 4.5l/100km or 52MPG US
A quick look in the garage finds that the best Fit (an older model) is only just breaking 52mpg. I don't know how badly you'd have to THRASH a Fit to only get 36mpg.
Now my my current daily is a 1.6 Renault, rated 9.7 city. Doing all city driving with a payload up to 800kg (~1800lbs) it's running 57% over NEDC.
If I consider the Jazz example, there's a 44% difference between NEDC and EPA.
Now if I multiply my NEDC figures, 9.7 becomes 14l/100km. That would mean my best tank of 6.05 was 130% over. Even the current tank which has been 100% with 800kg payload, would be sitting at 75% over.
So am I a hypermiling god or are you guys just not trying?
