Now I do accept that my car doesn't have the transmission losses of quattro, but the result on the dash was hugely impressive for a 1900kg 265hp 3.0 diesel auto....60.1mpg

That worked out to an equally impressive >53 real mpg.

But then having done my sums on comparative costs of driving like miss daisy and my usual more press-on pace, I decided to stick to what I know and love, speed!!!! For the additional £4 it costs me to cover the same 100 miles, I'll arrive with a bigger smile on my face.

That's mighty impressive!
