From my home, over a mile, why? (Assuming that the 30mph limit on the road makes you count it as urban).

It just happens to be a nice round number in some measurement systems and was used for some standard tests. When I had a car with an mpg gauge I would get 50mpg at 50mph, 60mpg at 40mph and 70mpg at 30mph (in 5th gear, constant speed, flat road etc). 30mph in 5th is impractical even in a small petrol engined car, and it was not much of a hit to use 4th.

The urban and extra-urban calculations are a lot more complex, since a simple steady speed was too easy to frig. http://www.vcacarfueldata.org.uk/information/fuel-consumption-testing- scheme.asp

Stick to your bicycle old man. Really, are you seriously saying that the NSL on a dual carriageway is 60mph? >>Yet again you demonstrate that you are an incompetent driver. > > LOL , ah the irony :) What irony? |
