So I was able to see two flat sections on my trip that I will use for steady state cruising on my way back home from Vegas, everything seems to be on a hill or slope in this part of the country. my calculated average from the display readings was 47.7 I was getting 53mpg trying to maintain 55mph for about 10 miles on a 60mph Highway at the beginning. but then the highways turn into 70 mph speed limits (which means everyone else was doing 80-85) so I had to stay at the right hand lane with the semi trucks 95% of the time, since we got 47 mpg with a/c on I don't thing that the 40.7 mpg at 70mph with the CVT Is accurate. Hopefully some of the guys with cvt's will also provide more examples of speed vs mpg to try and make that chart more accurate.
