You assumed that ICE maximum 76hp and electric motor maximum 67hp meets at the same time to get 143hp. MG1 RPM behaves as a CVT between ICE:MG2 RPM ratio to merge the two max hp closer together. I do not believe they actually meet though. There will be a loss during conversion but the torque gained from the conversion during low speed will offset that. By looking at the results, the conversion is beneficial because Prius weights 2,900 lbs and it gets extremely high mpg in the city. "Anyway, the 67 hp of MG2 (50kw) can not possibly be supplied by the MG1 ( 10kw or 13.4 hp)primarily. The bulk of the MG2 power input has to come from the Prius battery." You are right but only in high demand situations. During regular driving, as John stated, the battery gets discharged rarely. I estimate that 04 Prius can do 0-60 acceleration 10 times in a row in order for the battery to run low. Realistically, how often do you need to drive like that? Regarding about Prius track running out of battery.... Who knows, maybe performance HSD needs to have more powerful MG1. The work that TRD put in will definitely go into the next HSD Sports car.

Hi Usbseawolf2000: ___From the C&D article, they were speaking of 10.2 seconds on a full SOC and a tad under 15 seconds with 0 SOC. I don’t know exactly how they measured the Prius’ battery pack assistance or SOC but I know the 01-03 Prius BCM attempted to take the Ni-MH to ~ 56% actual capacity. If the same is true of the 04 for batter longevity, the 04 Prius’ 9.8 - 11.2 seconds to 60 is at the best end of the scale. If the pack is heading towards a similar charge of ~ 56%, 12 + seconds to 60 is more then likely the result over time. We will need to see the lab results in a few months to make sure but 0 - 60 times are already pretty low on the scale at 100% SOC and it can only go from bad to worse. ___Good Luck ___Wayne R. Gerdes |

I know 0 to 60 times and state of charge are of interest (do you hybrid owners spend much time worrying about SOC ?) but quiter roads sound good to me - snip - A vision for a more placid London with sound proof buildings, quieter roads surfaces free from potholes and ramps, no planes in the night sky and peaceful fuel cell vehicles rather than the chugging engines of diesel driven ones, was set out this week in London's ambient noise strategy. http://tinyurl.com/3gdy8 - Rob I like the sound of a well tuned exhaust sometimes Fruth |

| will you find the hydrogen production industry that will consume more energy than is borne by the hydrogen that it produces? Moreover, where will be the noisy, fossil fueled power plants that produce that energy? Or perhaps you forsee an expansion of nuclear generation, hardly a quiet enterprise either and not likely to win favor with the "greens". We seem to have gone full circle - there is NO free lunch! | |

interview this morning with Bill Ford, he not only renewed his commitment to hybrids, but said that there will be two more hybrd Fords in the next year or two, including another SUV. The journalist on the NPR piece also went on to say that "by this time next year" there will be hybrid Accords AND Camrys. As well as GM models? And I read a separate piece last night saying Ford HEV is well and truly set to be available this summer. |

| Other sources put the Camry hybrid as a 2006 model, so it's possible that it could appear early in 2005 (e.g. early debut of 2003 Corolla) but the Accord is more certain. | |

daysaylor it sounds like we pretty much agree on this one, how weird is that !? In my mind it does little good to shift the pollution to a different spot, much better to solve the problem rather than put a band-aid on it although the proposed noise barriers that also act to generate solar electricity sounds like a good compromise. |
|
| In my view, real solutions to transportation energy consumption and pollution will have more to do with changes in transportation systems and use patterns than in the efficiency of individual vehicles. | |
| I read the interview. Bill Ford also said he wishes the government would tax us another 50 cents a gallon on gas to make hybrids more viable. Then use that tax to give hybrid owners a rebate of up to $3000.00 to help offset that additional entry fee. If I remember my history we tossed some tea into the harbor for taxation that only helped some of the people. I,like Jefferson,would be willing to shed some blood to revolt against that kind of taxation. Because taxing people to "force" them to think correctly is as much despotism and anything we as a people have ever faced. Bill may have qualified his remarks by saying he knows such a tax has no legs in an election year but just the thought smacks of Communism to me. | |
