    It is rumored that the EV button will be back in production models of the phv. Toyota could implement your strategy there (EV off but battery power), but it is unlikely to go as far as you want. At higher power levels the batteries in at least the demo cars are not powerful enough, and the engine must go to less efficient power ranges to provide the power you call on it.

    The electrolyte in a Nimh battery is alkaline, so this is a true and easy distinction from the Li battery in the phv. It also conveys that you can not recharge the prius from external electricity, which is correct. Cordless makes you think you can. A Suburban is lead acid, so you would not be confused that a non-hybrid has this feature. So much better distinction than cordless, but Nickel metal battery prius is even more description..... Why do we not just call it the prius and plug in prius?

    I'd settle for plugless and plug-in. No confusion of metaphor and it's also alliterative.

    Avoiding unqualified Prius is future-proofing. Over time you'd expect the plug-in to take over from the plugless Prius as the norm.

    But what to call a BEV Prius. The "Ire"?

    Because cordless can be applied to efficiency and emission. Cordless MPG does not include energy input from the grid. Cordless emission is simply combustion engine's tailpipe emission, without emission from the grid. For example, Nissan advertises Leaf as zero emission. That's zero cordless (tailpipe) emission but Leaf requires a cord to be plugged in so what's the emission from the cord?

    Since PHV or EV indicate a cord (optional or required). Cordless indicates a hybrid without a cord.

    There is the focus and BEV focus. I don't think its all the confusing, but hell, how about convetional prius, plug-in brius, pure electric prius or PEP for short.



    Do you actually mean charge sustain? Or Cordless? Your language may be fooling you. My mileage is often low in the afternoon, as I used electricity to run airconditioning at lunch. The car then Generates extra electricity. Which is the false mpg lunch which is artificially high, or home which is artificially low (and lower still to run air-conditioning).

    My gasoline is actually refined with electricity from the same grid I use at home. But this is making it way too complicated.

    Why not report conventional mileage from the prius over a year (seasonality) and when we have the data gasoline, electricity and miles over the year from plug ins. I don't think we should have a knee jerk reaction to use more gasoline because the math is a little bit harder. We are in the Plug-in forum after all.

    So the alkaline emission is the same as a conventional cars, not counting charging and discharging on trips. Brilliant, but not very helpful. Why do you insist on the alkaline prius's emissions, on a thread about fuel consumption on the plug-in.

    Surely we should have a distinction of point sources of emissions. A high polluting car in LA is much more harmful than a power plant with scrubbers out in a low population and polution density area. Certainly there is a movement of some of the oil polution to the gulf coast refinery area and production sites of the oil sands.

    The leaf ZEV seems like quite a bad description since there is quite a bit of emissions associated. I am not sure historically, but it probably stems from CARB that created the initiative and decided a car like the honda accord was a partial zero emitions vehicle, which seems like an obfuscation only government bureaucrats can make.

    These are plug-in. We were on the point of discussion of inductive charging, where a PHEV or BEV could be recharged without plug-ing in. Certainly possible, and likely to happen. This is the same as a cordless phone. The prius phv is like my cordless razor, where I plug it in to recharge it but then its not tethered when I use it. Your use of cordless is incorrect English usage, but you seem quite tied to the idea, and are making very strange arguments. As such I will adopt the equally bad alkaline in response to posts that you say cordless.

    Your analogy doesn't work 100% because a cordless phone and mouse are cordless for a different reason. It's because the power it needs to run on and information it transmits is cordless.

    Back in the day before wifi, laptops were not cordless because you still had to plug it in for data, even when on battery power.

    It's common terminology to call a non-plug-in hybrid vehicle and cordless hybrid, as opposed to a plug-in hybrid.

    But a non-plug-in hybrid has no cord, it is not incorrect to call it cordless.

    i.e. there is a plug-in version, and a cordless version. It's clear in this context.

    It should. The link between the battery and the motors will handle more amps in the plug-in. This will DROP MPG.

    The more you accelerate, or the steeper the hill you are climbing, the worse your energy efficiency will be. If you do it in EV mode, which would show an infinite MPG, you would still have a lower trip MPG than if you accelerated more slowly, or the hill was less steep.

    I am confident that Toyota has done and will continue to find the optimum algorithm for MPG. It seems unlikely that a naive user is going to stumble upon an improvement that months of exhaustive testing has not found.

    Where users can add value is by adding knowledge that the car lacks (such as upcoming slopes and traffic conditions).

    No, I meant cordless. Please refer to my previous post if you are still confused.

    Phone and razor have their corded version (without a rechargeable battery) since were designed to operate indoor. I understand the point you guys are making that may be causing confusion. The usage is different.

    Cars operate outdoor. Name one EV or PHV that drives without rechargeable battery and operate only with a cord plugged in. Didn't think so.

    How can you call PHV Prius the "cordless" version when there is no Prius that drives with a cord plugged into a wall without a rechargeable battery?

    All the current PHVs and EVs have a cord to charge. All the charging stations require a cord to charge. Until we have induction / wireless (basically "virtual cord") charging stations and vehicles, I suggest we stick with the same term already widely used.

    Err. How many miles do you get from a charge of your cordless? :welcome:

    How do you charge your cordless prius. Does it take 5 gallons per charge?:(


    Keep driving your ancient propellerless dinosaur flesh munching prius. You are trying to force the coining of a deceptive term. You aren't fooling many except your little click of fanbois.

    With all due respect.
    I believe I used all those terms including propellorless correctly by your standards.

    Funny I didn't detect respect in that post at all. ;)

    Let's agree to disagree and you are free to use whatever you want. Peace.

    Corwyn, If I have the PHV in EV Mode, it will allow me to accelerate and get me up the hill, but the Battery will deplete faster. Knowing the Gas Engine can Help, the Battery/Electric Motor should be able to work with the Gas and achieve 50 mpg, instead of the Gas alone dropping to 9-20 mpg. This would Increase the trip's battery life.

    You should also realize that Customer Feedback is where Toyota and other companies get their Improvements. Companies don't have ALL the Brains under their roof. They need Customers too.
