It has been a years long process of staring at a Scanguage-II on many other vehicles to find what driving for optimal efficiency is. But once you get it, it becomes a habit.
~55mpg is more typical for me over short runs at an average of 60mph.
The enemy of even better fuel economy in this car is..
1) the car has a huge oil capacity and thus it takes an extended period of time for the oil to warm up and transition to the lowest level of friction possible.. easily solved with a partial grill block during winter.
2) the extreme rev-hang built into the ECU for the manual transmission model..
3) the shift indicator on the dash will mislead an unknowing driver into selecting a non-optimal gear with higher levels of friction and pumping losses that are not necessary.. the car actually likes being lugged at low rpm.. i shift into 6th gear in the city at 40mph. Always drive in the lowest gear you can get away with.
4) Underbody panels present in larger cars such as the Mazda 3 and Prius are missing here.
5) As you can see from the picture, the fuel economy is not measured beyond 70mpg. My scanguage II is in my wife's car to help her hypermile her small SUV. Plan to order another scanguage to verify the accuracy of the stock MPG meter.
I will do a video on my personal youtube channel detailing exactly how to drive this car for optimal fuel economy later on. In the meantime, here's a video of my old Honda Insight hypermiling at high speed.
