Hi Lars-ss:
___You are more then likely correct on all counts in regards to Hybrids. I still believe the 5-speed Insight can achieve 66 mpg at 65
mph in 65 degree temps given I usually receive 100 - 105 mpg at 39 - 59
mph w/out A/C but I am not sure as I don’t ever drive that fast. Given you live in the Phoenix heat, you just don’t stand a chance w/ 100% MAX A/C on at all times in a car with a rather underpowered ICE

The Le Sabre we rented however did receive 26.9 per the FCD (24 – 25 mpg actual possibly?) in the all-city Phoenix/Glendale environment running 100% MAX A/C but I was using rabbit and regular timing to its extremes as well as coasting from further then normal costing distances to achieve such. Out on the highway, I was just marvelously impressed is all …
___Good Luck
