Top 20 - MPG Record Holders

I set a new personal record. Over 700 miles and over 79 mpg on display. Calculated at pump shows 78.5 mpg.
here's my pic.

 

I did it 50 psi in tires. Summer with no air conditioning. 25 mph. Just over 700 miles

 

I don't go out of my way to fill up--I drive right past the gas station at the end of my long-ish commute, and prefer to fill then rather than coming back and stopping the other way when the car is cold.

 

I guess the top 20 list is dead. I posted a tank ranked at #6 according to current list and no update in like a month. I wanted to be on the list.

 

F8L hasn't logged on here since Jun or July, he might drop by later and update the list but for now you might want to copy/edit the list in your own post (check the messages since his last edit and make a new version of the list).

 

Even better if someone spends lots of time on here and wants the task a hand start a new thread I would make more than one list because a c is gonna be able to Kill a gen 3 lift back, etc

 

I would be willing to start one, but only with F8L's blessing. This is his baby.

 

Still holding on for him a week later? Lol

 

There's nothing wrong with linking back to F8L's thread and if he comes back, he can always wrap your posts into his thread. The moderators here can probably even merge the 2 threads at that point if need be. I say, "go for it".

 

ok...talked me into it

I will work on a new thread when I have some time later tonight.

 

New thread is up!

Oops wrong thread

 

I only drove about 60 miles, but I got a new record of 74.5 mpg. I think that's really good. I just want to give a description of how I did that to help others. I'm not looking for an acclaim. LOL! Today I tried a new technique. Basically, I tried to drive with the ICE running as moderately as possible. That's to say, I tried to have my MPG indicator hover around 50 mpg with the internal combustion engine running. That kept the battery charged. When on a flat for example in EV, I hit my cruise control up once or twice to engage the ICE. Then when I was going downhill, I would be on EV with 100 mpg. Going uphill slowly. I tried to keep my mpg as close to 50 mpg as possible. 34 mph seems to be a sweet spot. Of course I have other tricks. First of all, I use cruise control as much as possible. It does a much better job than I do. Putting the car in neutral lets the car roll further, pick up more speed going down hill, but unfortunately doesn't charge the battery. On steep down hills, putting the car into B charges the battery rapidly. If I have to stop for a light, I always put the car into D to slow down because it charges the battery. BTW, I always put my emergency blinkers on when I do this and only when it's safe. I was in the country on four lane roads with very little traffic. 2013 Prius 3.

 

Be careful with neutral and coasting. Damage can occur

 

(NB: this was not at all typical for me, nor under 'normal' conditions either.)

Others have done this for much greater distances, on flatter routes. There is an old 100 MPG thread around here somewhere.

When you get good, you'll do better than cruise control.

It also puts MG1 at risk of overspeed, if the ICE is off and than you roll up to above 46 MPH in a Gen3. (Other generations and model families have different threshold speeds. Actual damage speed is unknown, as an undetermined amount of safety margin is built in.) For safety and legal reasons, just keep it in D and feather the gas pedal to zero out the HSI meter.

Don't do this unless the hill has more than enough vertical to fully charge the battery with the regular brake pedal and D gear. For shorter hills where you don't fully charge the battery, using B is actually wasting energy.

Judicious use of the brake pedal (still in D, not N), not pegging the Charge portion of the HSI meter, does the same thing. Though 'coasting' in D with the HSI meter at zero (no thrust, no battery charging) will do the best overall, taking a long slow rolldown that will very seriously annoy any following traffic.

 

Man.. I see all you guys are driving with happy MGP.. My 2013 Prius Only can on 52.2mpg and Average speed 19mph.

 

Note that my picture above was not at all typical, nor under normal conditions. It was a special case.

There is nothing significantly wrong about your 52 MPG, though that display is a bit 'optimistic', meaning your real number is closer to 50. Your car's original EPA sticker listed 51 City, and has since been revised down (by changing EPA test rules) to just 49 City.

But with care, you should be able to do better. On the original federal CAFE scale, your car tests out at over 70 MPG, and if you work hard enough, that ought to be within reach. Though that would probably require no A/C, all accessories off, and either a pre-warmed engine (reset the Trip meter after warmup) or a very long trip, and far more attention to minor driving details than nearly all commuters are interested in.

Please check out the fuel economy questionnaire I posted to the other thread.

 

This is my last tank. The average fuel consumption is much better than standard prius values. To achieve good results it is necessary to have long commutes (at least 20 - 25 km. Summer and warm temps help as well). If your daily scenario is made of short commutes (5 - 8 km) this average is not achievable. The system (mainly ICE, transaxle) needs time to warm up and get the best efficiency.
