New car mileage

BMW had a Diesel in Europe that got about 65 mpg, no joke. I'm sure it had the VW tune...

im sure there are differences in displacement there too
i have seen VW diesels with only 3 cylinders there, and 1.2 liters


my diesel (here is the US) is the "small" one with 8 cylinders and 6.0 liters
