Steve-
thanks again for the further driving stats. I wish you had also noted your speed at the data points. I found both to be very informative from your first post. while I'm a newbie & inexperienced hybrid driver I'm working hard to get my numbers up, however I'm not seeing anything near what you're getting to. were there any stops/traffic lights in your second drive? what was your speed?
closest I've gotten to those numbers was on the cape (off season) last weekend when I could drive a steady 40-45mpg with no lights- suddenly I was getting 54mpg.
this was an eye opener, since my regular driving I struggle to stay near 47mpg. usually I'm driving locally about 30mph, often with stop lights every 1/2 mile or so. I struggle to keep the FCD at 60 without my speed going down to 20mph and getting tailgated.
some other interesting facets I've noticed in the hypermiling department. Steve is driving on different OEM tires than I have. I have the brigestones at max 44psi- I think you're running about 55psi, every little bit helps - I wonder if the additional 10 pounds reduces rolling resistance. it sure does from 30-40psi!
also, as I've mentioned before- there are 2 different engines in the hybrid civic; the 33a6 which is rated ULEV and has a 13 gallon tank. and the 3ycv which is rated AT-PZEV and has a 11 gallon tank (from my manual). since I can't seem to find out anything about these engines and what their actual difference is- I did a quick run down on the civic miileage stats. using tank size to determine engine, only did cvt's (since that's what I drive) with a minimum of 3 tanks listed (so I could tell tank size):
except for Kenny
(congrats)
the top 7 cvts and all the cvt's over 50mpg are ULEV engines!
now obviously- driving is the major factor in mpg efficiency- and these guys have all had their cars for a year or more to 'learn' how to hypermile them. but I still find it interesting that 90% of the top cars are the ULEV engine - why is that?
enough playing with smiles-
summer mileage is coming! (I hope)
