Great strides have been made in fuel efficiency in the last 10 years and BMW are probably the greatest exponents.
Don't be fooled into believing that trip computer readouts of any manufacturer are accurate, though. From experience, they're anywhere between 10 and 15% optimistic. Fuel management systems in vehicles are based on achieving a chemical balance in the combustion chamber and controlling that by measuring constituents of exhaust gases. There's no direct measurement of fuel flow in an mpg sense so any mpg measurements are simply a mathematical approximation. And nobody wants their approximations to be pessimistic
Anyway, back to show us your rig
