Top 20 - MPG Record Holders

You're in the spreadsheet:


"F8L" will have to edit the 'first post.'

Come on guys, got to get those last 3 entries in the 60s improved to 70 mpg+

 

Thanks Bob.

Those are the numbers from my first post, not #688.

Opps, sorry. Its fixed and you'll notice it updated all references to the spreadsheet at the same time.

This has me thinking I may see how much better mpg I can get with my c

 

if you want to know what a person gets then look at fuelly and you can see what they get over the long run. I think that is how you can see what a person gets. and more importantly how a car performs mpg I find that driving a route for mpg sounds fun to me.

 

My sister in law was telling me at Oregons womans prison they have a prius that drives continually around the prison grounds. they drive real slow. I wonder what the mpg must be looks like the state of Oregon made a great choice in what car to do this task.

ps dont ask me how she knows

 

Actually an electric car would have been the best choice for that kind of job.

 

I dont think so this car drives 24 hrs a day. it never stops except to change driver/guard, and circles the facility

 

well it has to get gas and be serviced i think they may have two. not sure

 

Ya, I suppose if it is going 24/7 then a Prius would be best...a Prius C to be exact.

 

After thinking about it I realize that my sister in law must not have told me the whole story. the cars must have to stop some so I am not shure if they patrol when there are prisioners outside. If there are more than one car it may be 2 hrs on and 2hrs off this may allow enough time for recharge?? not sure.

 

i tried some of these hypermiling techniques you mention here..particularly cruise control at low speed ...i notice a lot of battery is used....
i thought avoiding battery use as much as possible is recommended?

 

How is your mpg? I still need to read more about what works best with my car.

I drive a c and with it I can easily get trip mpg up if I drive longer. it seems that short trips is a brick wall to mpg. my drive to work in the morning is 2.9 miles. and I can only get mpg to 55 mpg but it is usually about 50. If I drive further like one day I had to drive back home because I forgot my ID. The extra couple miles increased mpg to over 60mpg. I notice driving arround town once my car gets warm it will go up to almost 90 mpg driving. one day I drove 20 miles in town with traffic and stop lights ect. I got 92 mpg for the trip. I use ev as much as possible running the battery down doing this. so ev seems to work great at the low speeds I drive in my prius c.

I have also heard some say to keep your battery charged up and everything works better. I need to do a lot more trial and error to see. It could be driving at higher speeds, and having the batt charged up will increase mpg? I just don't know yet.

 

First off, do the experiment. As my drill instructor used to say, 'A grain of observation out-weights 10 lbs of b*llsh*t any day.'

Now my experience has been that without external charging, there is no way to effectively "charge the battery" without burning extra fuel. This is how I see the Prius traction battery:

• part of the transmission - it is key to switching between "normal" and "energy recirculate" mode by buffering the instantaneous current flow reversals between MG1 and MG2
• below 42 mph - allows the engine to cycle ON-OFF while maintaining a constant speed, reducing the engine overhead, fuel cost

Together, these two functions keep the Prius engine running at maximum efficiency. Without having a plug-in, there is no need to do anything but keep the traction battery temperature as cool as possible by avoiding excessive loads.

i notice that with cruise control seems to work well....below 42mph....better maybe than pulse/glide

i was worried about battery use to much...but it does seem to even out..staying at 52SOC

 

not sure what that means in practice??...

 

The HSD has two electrical energy flows:

• "normal" - MG1 works as a generator and sends 28% of the power to MG2
• "energy recirculate" - MG2 works as a generator and sends 28% to MG1 to increase the torque (slow the engine) to a more fuel efficient point

Although this change happens electronically, the traction battery provides the momentary energy needed when switching from one to the other mode.

Is this true even during the initial warm-up mode?

 

These are independent of warm-up state. It has more to do with vehicle speed.
