Following up on the recent fuel consumption discussion, I though this might be interesting. It's the fuel consumption display from my Signum.
The actual fuel consumption will be some 5% less than the figure shown, so it will actually be nearly 48mpg. I have seen 52.5mpg on the display (an actual 49.9mpg when I filled the tank).
See I told you I drive like a Grandad! (and listen to Radio Cambridgeshire)
