It was "treated as new" because no one at Toyota Corporate had ever announced OFFICIALLY that Toyota was looking into PEVs as an item they would sell as a production car.
 
This was the first time.

i am about to purchase a 2006 prius,and would like to know if there is a after market charger i could use in my garage at a reasonable price. also would charging the batteries hurt it? and would i have to add additional batteries to attain some results and still be cost efficient-mike please respond-thank you michaeltnevillecomcast.net

It would void your warranty, and the Prius, and other Hybrids, are not made to be "topped' off, but rather keep the battery at about 70-75%. This is to give head room for the regenerative breaking system to charge while driving, etc.
 
To keep it at 100% would actually shorten the battery life and impair the system, I believe.

The beauty of the Prius and other Hybrid systems is that they automatically recharge themselves.
 
No plug-in is needed!

Yes!
 
The best of both for the real world.

Yes, there is a beauty with the Prius and other Hybrid systems in that they automatically recharge themselves.
 
But true beauty is a Prius or hybird where you have an 'optional' ability to plug in and get a 100 mile boost. So for your commuter workweek, you can average 100 miles per gallon. You still don't have to plug in -- but if you want to get a boost, you could average 100 mpg for those everyday trips.

How can you get 100mpg except for coasting?
Would be great to hear. I have had my 2006 Prius for about 2 months now and am getting 47.5 mpg. Thanks for the info. I'm in Alaska also.

timinalaska,
 
You must be an optimist looking through rose colored glasses. Electric cost to plug-in and charge a battery is not free. You have to equate the cost to equvalent gallons of gas and in doing so recalculate you effective mileage. Remember no energy conversion is 100% efficient coal/hydro > electric> transformers for distribution > battery > mechanical car; there is alway loss!. I surmise you might be suprised to find that if you did have and elctric pulg-in your effective gas mileage would probably go down ; not up.

For reference, please go to www.calcars.org. In order to get 100 mpg, you must install an after-market conversion where additional batteries that essentially fuel the car for the first 100 miles of a trip are installed.
 
The 100 mpg does not hold true for the standard prius, it's for the optional plug-in hybrids, or PHEV. You can convert the standart Prius into a PHEV. And of course there is always loss with energy, but for an overnight charge with the conversion, the electricity will cost you about $1.00. Compare that to an average of $3.00 a gallon for gasoline across the U.S. And while coal plants are still dirty, in California, most of California's energy does not come from coal and it's much cleaner. Unfortunately, coal still account for 60 % of our fuel for electricity for the rest of the U.S.
 
But is it easier to clean up millions of dirty cars, or is it better to clean up a relatively small number of coal plants. And as our sources for electricity become cleaner, the optional plug in hybrid makes even more sense.
 
Please call Toyota and other hybrid makers to encourage them to make these cars. The cars are available today, but it's engineers on their own that are converting these cars at a high cost. If Toyota can do this in large scale, you could have a hybrid that gets a 100 miles per gallon boost from an overnight charge that costs less than a $1.00.

Okay I read you article. It uses old electric prices of 9 cents per kwh. They are double and triple that now. The poultion does not take into account the electric generation. The addtional batteries add to the weight of the car and considerable slow it down and also reduce effective mpg. The PHEV (Plug-In Hybrids what the aritcle says, I think it is Plugin Hybrid Electric Vehicles) costs $3-5 more than a hybrid which cost $3-5k more than a conventional ICE.
 
Okay thats only a couple of major flaws:
 
(1) electric cost is way off
(2) electric generation not cinsidered in polution
(3) battery weight increase not compensated for
(4) 3-5K $ additonal cost not considered.
 
Will a PHEV fly, yes it will 3-5% of the current hybrid buyers will buy a PHEV and hybrid buyers account for 3-5% of all new car sales.
 
So PHEV will account for .09-.25% of all new car sales and will save the world from polution!
 
And where or where does it say 100 mile per gallon boost for $1.00 (which by the way is priced incorrectly) ? 100 miles per gallon by not counting the electric charge or the equivalent cost to generate the eletricity. Even using their figures it cost $0.81 to go 30 miles and a gas cost of $3.00 per gallon at noraml Prius of 45 mpg. To figure out that you are getting 100 mpg actually means the following
 
45 mpg at $3.00 = $0.0667 per gallons use x gallons
 
Electric cost 0.81/30 = $0.027 per gallon electric cost
use y gallons
 
100 miles/gallon at effective $3.00 gallon = $0.03
 
  $0.0667*x + $0.027*y = $0.03
 
using Y as the dependent and solving
 
.027y = -.0667x+.03
 
    y= ( -.0667x )/.027 + .03/.027
 
    y =-2.47X + 1.11
 
The y intercept is when x= 0.44
 
In order to be real numbers x has to be less than 0.44 whch means that in order to achieve 100 mpg most of the power and energy has to come from the battery charge all of the time 56%. Hey i can get 99 mpg in my Accord V6 coasting to a stop in 6th gear!
  
 
I think my windmill perpetual motion car will do better!

P.S. I am going to solve my gas problems by winning the Shell gasoline giveaway by winning the lifetime gasoline supply.
