So I promised I would post some of my first experiences and I thought I would give you a brief background of my hypermiling experience to put things in context.
First I bought my 2006 Honda insight in March of 2009, I've now put some 20K miles on her and started from 46.8 MPG to easily getting 60 plus on a less than ideal commute, some pretty large hills, several stop and goes. I learned to time the lights on the 45 MPH stretch so I hardly get caught by them anymore. The tires are at 55psi on this one and I ridge ride. I do not pulse and glide (neutral) or any more advanced techniques. I also on average am at or above the speed limit for most of the ride. Ok enough on the history, but wanted you to get a feel that I'm no longer a newbie at this, not an expert either!
So my first set of runs on the prius, and I know the Honda insight #'s were estimated using the old inflated method and the new Prius C two is with the new method that is harder on the cars. So I read around here and I saw several in the 50's and some in near 60. So I set my expectation that I would be happy with 50 thinking I'm not a super guru of hypermiling. Boy was I, and am I pleased with my results thus far.
Here was my run back from the dealer, picking up the wife at a 2nd location and heading home.
This was a mix of highway and city, temps were 83, it had just rained, car was warm, and tires were at 35psi. Moderate traffic not generally didn't score less than 4 bars on any start to stop
The next morning was a trip to work:
This was a brisk 68 degree morning, very low traffic, tires at 44psi, I think I hardly had to stop, but for one stop sign and 2 red lights all of which I coasted to stops. Lowest I scored were 4's. Oh this was a cold start run, with the first 3-4 blocks being 40mpg which includes 1 of 3 large hills I hit on my trip.
Then the nightmare trip back from work:
I say nightmare because like most we never want to have to jam on our brakes! So this was in 86 degree weather, heavy traffic and I hit one stop light just horribly and got a 2 bar stop due to the bad timing of the light and just shortly after starting on another light I had to emergency stop to avoid an accident as around here people can't pull into a business without first stopping in the middle of the street! /roadrage/ So as you can imagine I was not so eco on the start after that and got a 3 start
But still eeked out above 70mpg
Ok to give an approx. of my commute to work. The first half block is down hill. I live at the peak of the block, then it is a relatively flat 5-10% down grade for 2 blocks. After that I get to climb about a block long 35-40% grade after which I am rewarded with a 10-15% down grade for 3-4 blocks. After that it is a 45% climb for about half a block, after which is levels out again and maybe a 5% downgrade at most rather flat for about the next 2 miles. Here I hit a stop sign and 2 lights. All of this is 25-30 mph zones. After this I turn on to a parkway that is 35-40mph and includes a suspension bridge with probably a 20-25% grade up and down for a block and a flat couple of blocks this has 3 lights 1 before the bridge one after and one before I turn on the county road. After which I get on to a County Road 45mph, and have 4 lights that overall I know the timing off when I was at the speeds of the Honda. From there I have a flat block another turn and a flat block and I'm there. Totals about 6.2 miles each way. So not an ideal commute. I can alternatively hit a highway for part of the trip, but will go into that when I do a few runs that way next week.
Techniques I used on these runs include ridge riding, staying in EV up to 35 and a less aggressive pedal then I used in the Honda. I will keep experimenting with getting out of EV sooner as some have suggested, but considering the results thus far I'm very pleased to top my expectation of 50's with some solid 70's
