That was in 2018 so I can't remember the #'s. I just used the computer fuel economy readings in ICE mode at a few speeds. I find the fuel economy is largely dependent on highway velocity. Wind resistance is proportional to velocity squared, so 20% faster = 44 % more fuel used but 20% less time, so 20 % worse fuel economy overall. I concentrate on passenger smoothness and we don't have many traffic jams where I drive. Last trip I did averaged 7.2 l/100k (31 MPG US I think) & one before that was 6.8.What kind of mpgs did you record on your trips?
