Most HV miles per Tank

Yes! You are!

 

Hmmm, both of those may need some explanation.

 

My coffee is brisk.

 

Brisk is easy to explain.

Owner commonly make the assumption that using the gas engine means an efficiency penalty. They are unaware that it runs in an optimized manner, taking advantage of having a power-split-device interacting to 2 electric motors and a battery.

Accelerating with generous pedal will often result in a lot of electricity being generated on-the-fly, the result of the gas engine settling in on a RPM with minimal waste. Some of that electricity is consumed immediately for propulsion power and some goes to recharging the battery. The operation is quite dynamic.

In other words, the overall MPG is what to consider, not the acceleration itself. Far too often, owners see the power-bar spike and believe that is a bad thing. The design reveals it typically is not.

 

It needs to be pointed out that, contrary to our intuition based on our experience with traditional ICE systems, rapid acceleration to a given speed does not inherently use more energy than accelerating to that same speed at a lower rate. The laws of physics simply state that it takes a certain amount of energy to accelerate a given mass to a given speed. What differs is the efficiency of the power source in the various acceleration scenarios. The power split device is an elegant solution to this problem. The electric motor has a very flat efficiency curve over quite a wide range of RPM. And if power from the ICE is needed, the strategy is to have it running at an RPM where it is most efficient, even if that mean powering a generator to drive an electric motor, or charge the battery.

 

Makes sense, thanks John. Driving the PiP really is quite different from driving the standard gas guzzler - very different beasts.

 

I guess I'll never really know, I'm a filler upper at two pips lefter.

 

i keep my whisk broom in my brisk room.

 

Its really a function of your usage of the car. In my case, being retired, most of my trips are local and short. Over the past 15 months I had three 2-month periods where I made no long trips. My EV miles for those "tanks of gas" have been over 1000 miles and the tanks of gas have been about 4 to 7 gallons. On the other hand when I have gone on longer trips 4 tanks of gas corresponded to less than 100 EV miles each. So asking how many EV miles per tank of gas is sort of like asking "How tall is a tree?"

 

me too.

 

I am surprise to see only 500, 600 miles range, I thought most of you are running on EV and will get way more than that. I get 600 miles plus easy with only one charge per day and drive about 40 miles. Probably get over 700 miles if I dare to push that blinking fuel light a little..

 

Yes, but the OP is asking how many miles in HV only.

 

exactly, LA, you are misunderstanding the premise. if you want to know total miles per tank, start a new thread, or there may be an existing one.

 

Sorry guys... I am new to Prius, only got it 2 months... IC what this is now... No charging, just use the PIP in hybrid mode, correct?

The only time I can do this is when I am going on a long trip, like from LA to Vegas... I will do this sometime in the future and let you know.

 

I managed to get 3.8 L/100 km this morning, (pure HV mode, no plugging in) which is almost 62 MPG. It was all city driving; my regular commute, where 4.2-4.4 is a typical number most days.

The only thing I may have done differently is that since I was a bit early, I was easier on the accelerator than normal, careful not to let the indicator get into the red "pwr zone" on the HSI.

 

There's no reason to red "pwr zone".

The point of the indicator is to tell you to avoid staying in it for too long. Brief usage will not bring down overall effiicency.

 

Good advice, but it seems logical that if less is good, then none is better.
