maybe you can do more exact EPA rating calculations using my formulae (useful when you could not get from
Fuel Economy )
I think you did 8.7 conversion to 27 mpg, but if 8.7 is EU homologated average the using more acurate conversion is 24.7 mpg and you are 9% better of your "x % above EPA"

A good and easy conversion formula between EPA or EU average fuel consumption is as follows:
EPA(usmpg)= 205.87/EU(L/100km)
EU(L/100km)= 202.04/EPA(mpg)
this method has only +- 14% error because of big differences between city homologation cycle. This error is around +-3% for EU 3.5 to 6.5 L/100 km (or EPA around 27 mpg).

EPA and EU urban/city cycle homologation are so different that there is a good aproach if you don't use more variables (engine size, axle ratio, drag, engine type...)
