70 mpg with no charge

driving gently and keeping it under 35mph you will get alot of EV driving after battery is depleted. Did you watch your small EV light come on alot around those city streets? I did this quite abit yesterday and was surprised myself how good it does in HV mode around city under 40mph.

But if you get over 40mph the mpg IMO seems to drop down closer the NON PiP range in hi 50s. I still think the Pip always gets at least 10mpg better then a non PiP all things being equal in HV mode....its due to the larger PiP battery.

yes, i see 70-75 quite a bit around town with no plug juice. this was covered i a way back thread from the spring. gen III is more efficient than II and pip is even better.

 

Agreed. The GenIII can do 70+ on trips around town if the traffic is light and/or conditions are right.

 

No surprise, as the non-PIP can do this in the right city or low speed conditions too. I've had a number of round trip commutes, 36 miles with substantial hills, hit 72 to 76 mpg when the traffic conditions and stop lights and weather were favorable.

Remember that 50 MPG is the EPA label, which is sharply derated from the CAFE tests because most drivers can't or won't drive like the CAFE test cycle. The non-PIP's CAFE rating is a bit over 70 MPG. Skilled hypermilers in favorable conditions have topped 100 MPG. A PIP with depleted battery should be able to produce similar results.

 

Prius PHV ICE warms up faster than a regular Prius. Perhaps that also helped with the 18 miles trip.

 

i'm not sure what you're asking here, but, you cannot keep it in ev if you have no charge left. yes, the regular prius behaves the same way.

 

The PiP has a bigger battery that is available in HV mode. When you run out of battery you go down to 0.1 miles range, but when your empty and recharge from going downhill, it wont show any EV range until it gets to 0.9 mi range. I think those extra 0.8 mi are available in HV. If you recharged to 0.8 mi from driving, but then used it up before it ever got to 0.9, you would never know, it would only show you HV mode.

So one difference might be that when the regular prius has charged its battery, it will stop, and the PiP can keep harnessing the generated power decreasing the need to use the ICE.

 

The battery in the PHV is never fully depleted because the computer will not let you fully discharge a li-ion battery. Once you have used up the EV mode there is still enough power left to let you drive under 40 just like a regular prius.
