High mpg = using brakes

Instead of using my usual gas savings procedures ( lightly accelerating, using regen charge and stealth) I decided to try a brand new procedure. Knowing that after about 5 min I would have a long series of downhill rolls I reset the comsumption screen. At the end of this downhill roll with two short uphill sections my consumption screen read 90 MPG. I then continued along mostly in cruise control to lose an additional 500 feet in altitude. ALL in all the total altitude drop was about 1000 feet,(approximately) The second portion being more gradual. I am using the same procedure that many of our techs use to get thier incredible mileage results BUT refuse to tell you. This was all done with the luck of NOT making every light, but having to come to a complete stop, for the most part. HOW did I do this.........the trick is to leave the car in drive, no CC, and when the car accelerates past the speed limit to 65, 75 85mph, your choice, then use the brake pedal judiciously depending on the rate of deceleration required for driving conditions. It seems that the more pressure applied the greater the regenerative charge to the HV, in turn later to be used again as needed. We all I think, are aware thar the higher the average consumption during the life of any one full tank, the higher is the end average fuel consumption. When I backed into my garage the screen read 56.8 mpg, which is quite good for a 47 mile one way trip. The trip to, I also reset but used mostly CC. This along with REBOOTING if: you have not done it OR replaced the 12V Bat. My rebooting experience still yielded 4-7 mpg more! As for calculating the mpg by fuel consumed and miles driven that is impossible and a waste of time. ( unless done on a very long term basis ) Why do I say this?, because one cannot tell when the gas tank is full! I am very curious to see what results I obtain coming down the Sierra Nevada mountain range. I believe I can obtain over 100 mpg EASY. :cheer2:

 

No! that will be my future test. Yesterday I took a trip to Jackson Rancheria (47 miles, each way) using two different procedures each way. Although I have used the braking effect before ( Evans suggestion ) I did not use it as extensively as yesterday. The 90 mpg astounded me. I have also shown 90 mpg before , after tanking up and resetting at the top of the hill at Auburn. But, that 90 mpg reading was accidental and I really had not analyzed what had happened. It appears as tho, the regen increases with more brake pedal pressure. I cannot prove this as I have no OBDII tester. The most enjoyable part of the trip was when a CHP caught a guy passing me in the passing zone doing about 85 mph. Schadenfreude! :cheer2:

 

If, (the engine was not turned on) then your screen is blank which equals ZERO in all directions, NEVER did I infer "using the brakes and stopping" Where did that come from? I was exactly speaking of converting potential energy! That WAS the point of the post. " Going downhill yields better mileage " Now that was absolutely mind boggeling! You have totally upset my tranquility and missed my point! Congradulations!!!

 

1000 feet, quote: approximately. Yes, I agree on 2nd, point. This is why I treated the results separately.

 

Yes, after coming back into the Sacto area I was forced to stop at the red lights, all part of the same test. As for spelling I totally confess all my transgressions in that respect. I like Evans quote from Mark Twain. As to the rest of your posts we agree in every area.

 

It is very important to get thru this warm-up stage. In any event, my test does not prove anything after averaging the high and low numbers I expect around 50 mpg. The higher mpg figures are exciting for a short period and help confer genius on the persona, no matter how misleading that may be.....................

 

Don't feel bad, we all have some sort of failing(s)

 

Hello teeasal! I actually went up the hill before I came down the hill, so I was ahead of the game. I get my gas using a credit card so, I don't have to pay anything. Is the MFD reading a manipulated display? Or, one segment of your driving? And it's not true of the reward, GOD is going to give me a huge trophy for conserving his Mother Earth. NO, it is not a joke, this is dead serious. But THANKS for your input! :cheer2:

 

I promised to get back to this subject again and after two tanks I have to report that VERY light use of the brakes to produce more regeneration does not really seem to help. My last two tanke were 45mpg, both on the MFD and by calculating my mileage. Nor did rebooting help. My numbers only seem to help in the beginning, by eliminating warm-up and resetting the amg. However the computers do not forget, and the preponderance of my driving is 10-15 miles of suburbia driving with 6-10 stoplights or stopsigns. The experiment did however prove that there is nothing wrong with my car, I can still average 54mpg or greater on a 1-2 hour trip. Sorry for any confusion on my posts, I was mostly interested in knowing if anyone else had experimented with either rebooting or light brake use. :cheer2:
