I haven't had my TT long enough to compile figures, but here are the figures on my Class C that I had for 10 years.
60 mph = 9 mpg
70 mph = 6 mpg
That was a 17% increase in speed with a 33% decrease in fuel efficiency. Fastest may not be your best choice, for a plethora of reasons.
I agree with you, but I did a test between fill ups and found that at 75 I`m getting about .3 better mileage than at 67. The reason I noticed is that the engine is making more torque with the higher rpms. I also noticed on my dash command app that the throttle opening is less at the higher speeds.
