Replying to: midnightcowboy (Aug 28, 2006 1:00 pm) 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.

Replying to: timinalaska (Aug 29, 2006 2:38 pm) 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. |

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. YEMMV E=electric MidCow

Replying to: midnightcowboy (Aug 30, 2006 4:21 am) 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.

Replying to: timinalaska (Aug 30, 2006 9:41 am) 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! MidCow P.S. I am going to solve my gas problems by winning the Shell gasoline giveaway by winning the lifetime gasoline supply.

Replying to: midnightcowboy (Aug 30, 2006 11:06 am) I had a little trouble following the numbers afterwards Let's try my math on your figures. " Gas mileage assuming 45 mpg at $3.00/gal =6.67cents/mile Electric cost 0.81/30 = 2.7cents/mile And now for "Mathematics - the most overrated Science" To get 100 miles/gallon at effective $3.00 gallon Is another way of saying 300 cents will get us 100 miles Let z be the number of miles driven on gas :- We will need to drive z miles  6.67c/mile And 100-z miles on battery 2.7cents/mile Then 300 = z miles at 6.67cents + (100-z miles)at 2.7 cents Thus 300 = z(6.67-2.7) + 270 Thence 300-270 = z (3.97) Whence 30/3.97 = z Hence z = 7.55667506297229219143576826196474 Ergo you would need to drive 7.5miles on gas and 92.5miles on the battery which is basically what you are saying Midcow The 7.5 miles would not warm up your engine according to gagrice so your engine gas mileage would be down by 30% meaning you would need even more miles on the battery to make 100mpg. And [5] Loss of interest on your $3-5k Phev premium had it been invested instead. T2

Replying to: toyolla2 (Sep 04, 2006 4:25 pm) One last point. Will the extra batteries in this possible PHEV have enough power to carry the Prius to 70 MPH cruising speed without calling on the ICE? If not, it is NOT going to be worth much to most commuters. |
