    Weird yes. Look like Latin literature used in the bygone days of the type setting industry (also carried over modernly on some web aps) ... I think sometimes it's simply used as a place holder. :confused:

    Not necessarily so. Since we now know the Ev packs are seperate and not regen charged, It means their use will be at the descetion of the driver. (No blended mode) EV or HV, you choose.
    Everyone is hung up on the 13 mile range and thinks this car would not be beneficial to a long distance driver. I disagree.
    A smart driver who travels long distance would forget about the "13 mile" ev range and use Ev mode over known low mileage segments that typically impact mpg averages negatively.
    Maybe to climb hills, the slow and go through downtown, the beginning and end of the drive, what ever is most efficient.
    And of course us EV for the short round trips that they might do on weekend or whatever.

    I bet I could get 100 mpg out of the PHV Prius over my 100 mile/per day round trip.

    That would be great! I asked a month or so ago if the EV would be selectable and was told no, the battery would be used first, then enter standard hybrid mode when the battery was depleted. Still, we get supposed Prius owners that freak out when we suggest they don't drive 85 mph to improve their milage...:rolleyes:

    Well, those of us who can get into the 70's mpg range on the Gen II will likely be able to get 140mpg in a stock Prius PHEV anyway ... while the lead foot'ers who ponder why they only get 38mpg (while they do 85mph) ... will STILL wonder why their PHEV STILL only gets 38mpg. There are way too many variables to say what a PHEV gets, mpg wise.

    These are dishonest and meaningless reports of MPG numbers for plug-in vehicles, and they are false marketing sponsored by the government. EPA needs to update how they report MPG numbers for plug-in vehicles. You can get "infinite" MPG with a plug-in vehicle if you recharge it every ten miles but that doesn't mean anything.

    Separate MPKWH and MPG numbers for plug-in vehicles would be more appropriate, each representing the extreme cases: the gas engine never on and the vehicle never plugged in, respectively.

    So we'll wait for a report from those who drove the plug-in. (Remember Toyota had that event in San Diego a few weeks back).

    What would really be useful is not just the MPG numbers but the MPG numbers + MPKWH numbers together. Then we could get the real picture. But I doubt if anyone has a separate watt-hour meter in their garage for their plug-in vehicle or I don't think Toyota has included a built-in watt-hour meter for the plug-in Prius.

    How much do you think Toyota will charge extra for the PHEV Prius?

    I have no idea. The initial configuration could be anything. What's the most popular selling model right now? It will probably resemble that, plus the price-premium.

    The target price-premium has been in the $3-5k range. That's well within the current model pricing. Where will the plug-in be positioned?

    Per kWh cost of lithium in high-volume production is a big unknown too.

    $1000/kWh is the popular number to throw around, but the latest on the leaf suggests they've managed to get it down to around $375/kWh--though some experts are skeptical they've actually achived this. Most pundits feel that the current cost should be around $600-700 right now with a target of around $450/kWh in the next couple years as manufacturing ramps up.

    How did you compute 75 MPG (US)?

    2.6L/100km converts to 90.5 MPG (US) or 108.6 MPG (Imperial). Just type into the Google box "2.6l/100km in mpg" and press Enter. I'm not trying to be an @$$... The headline PHV Plug-In to average 90 MPG sounds better don't you think?

    As an aside, the 20km EV range works really well for my driving, so I can't wait... my chequebook is ready Toyota!!! Please hurry so I don't jump the gun and buy a Volt (ugh).

    That's if you use the Euro numbers. The US MPG numbers are lower b/c of the new EPA testing, remember?

    50% increased in EU cycle (3.6 l/100km to 2.6 l/100km). If we multiply the EPA 50 MPG with 1.5 then we get 75 MPG.

    mpg number for a phev... funny... what if you only commute 6 miles to work and you can charger there?... then it's a lot higher, isn't it?........

    the epa needs to be revamped... again.... phev's should have a mileage count to their mpg... 5 miles = x mpg, 10 = x mpg.... 15.... 20.... etc...

    As I explained before, you need both the MPG and MPKWH numbers. Separate MPKWH and MPG numbers for plug-in vehicles would be more appropriate, each representing the extreme cases: the gas engine never on and the vehicle never plugged in, respectively.

    Plug-in vehicles are partially electric vehicles and MPG values alone are insufficient to describe their fuel efficiency, as the gas is accounted for but the electricity is left out. 75 MPG, 200 MPG, etc. are just false marketing that hides the fact that you still get an electric bill and use precious energy resources through the electric power grid.

    I would love it if the car could get 75 MPG but I also feel like with the speedy recharge times this plug-in hybrid would raise the electric bill significantly. I know I watch my KWh on my electric bill and constantly look for ways to use less energy.

    Why would the SPEED of the recharge have any bearing on the electric bill? You pay for the total quantity of KWh used not how fast you use them. So other than heat loss and other inefficiencies which might increase over a longer charging cycle it should make no difference whether it takes 2 hours or 4 hours to recharge a given pack size.

    Similarly your electric meter doesn't care if you are using 120 or 240 volt AC to charge the pack, a KWh is a KWh regardless of the voltage (however higher voltages suffer less line loss and are therefore more efficient).

    I personally feel that rating the PHV will become far more difficult if Toyota doesn't come up with a distance per kWh rating for the EV only mode.

    Theoretically, for trips 10 miles or less, you could go months without refueling the gas tank and be achieving far above 100mpg. What that doesn't consider is the source of the electricity for EV and what the efficiency from power generation to delivery to the wheels is (if that could ever be translated to MPG equivalent).

    This also brings up a side question - if a bulk of your mileage is EV - do your oil change intervals matter as much?

    Where I live, I have a two tiered power plan plus demand with rates varying by summer and winter. For summer, the first tier is off-peak where electricity is maybe 4.159¢ per kWh (9p-9a and weekends and major holidays). On-peak (9a-9p) is 7.434¢ per kWh. HOWEVER - there's also a peak demand charge that makes up for the low-ish rates. During peak times, the 1 hour where the most kWh are consumed for that billing cycle is considered the peak demand, and that's billed at $13.372 per kWh.

    In other words, if I HAD to charge during the day, I'd want it to happen slowly, and preferably when the A/C is not running to keep the demand charge down. Looking at those rates, it'd be significantly in my favor to charge at night.

    The demo PHV has a 3kWh overall battery pack. The cost to charge isn't all that high at 120V considering the charger draws max 12A, feeding approx 1kW to the pack. At 240V, charge time is cut in half but I'd end up potentially paying more if it were during peak time and I had other appliances running (i.e. AC).

    I don't know what the 'tank life' is for gasoline, but perhaps some PHV users ought to get recommendation to use fuel stabilizer if only gassing up every couple months or so.

    Not to be cynical, but could happen.
