Yea, but I think trying to get 99+ mpg while usually in a hurry to the next destination with about a 2:8 electric to gas ratio is just for dreaming .
'In a hurry' and 'California traffic' are probably the main forces preventing you from reaching these numbers.
On yesterday morning's commute I was practicing my hypermiling skills- The Scangauge II said I got 80 mpg using my 2010 Toyota Prius III going to work using my normal 15.8 mile commute (65 degrees Fahrenheit - 6am-6:45am with an overall drop of 300 feet in elevation no rain ) the onboard computer Trip B estimated a slightly higher at 83.4 mpg. I was shooting for 99.9 mpg so I wasn't really happy with the outcome - my results were about 10 mpg below my best and 5 mpg below my par. My 2010 Prius on board computer Trip A estimates a 66 mpg for +400 miles but usually it is about 3 mpg too high. Last summer I had two 68 mpg tanks about 3 mpg below my best. However, I'm a skilled hypermiler so my fuel efficiency results are higher than normal. I am still using the original Yokohama Avid S33d tires and the dealership auto mechanic said that it looks like I never used my brake pads... Attched are photos of the results ...
In my old 2005 prius, regular daily commute. Really had to work at it hard tho. Work at it a bit, you will find that you to can do better. Enjoy Your car!
But some can do it for the entire tank -- on a non-plugin car. New World Record Challenge: over 50km/L(117mpg) tank
Almost always have time for some of it. It isn't an all-or-nothing thing, but has a broad menu with many options, select what fits the situation.
