In another word, pushing the ICE to do more work by increasing more stress. Hybrid works completely the other way around. By choosing two opposite powertrains, the stress can be split into two. The benefits created by both powertrains is the synergy effect which translates to more power, less emission and fuel usage. ICE used in HSD does not need to reach high RPM either. For example, Prius ICE output max 76hp at around 5,000 RPM. The real issue is the realiability of the battery pack. Let me first say that all your experiences with battery do not apply to hybrid vehicle batteries. Everything you ever used that had battery utilized battery in a "dumb" way. You fully charge it so that you can fully drain it and repeat the cycle. That behavior damages the battery and consumer electronic NiMH do not last over 1,000 recharges. Since HV battery pack usage is managed and protected by a dedicated CPU (battery management unit), HV packs last a lot(10x) longer! To go into detail, not every hybrid design can take care of the battery pack the same way. HSD can recharge the battery on demand. It is possible because there are two electric motor when one is driving the wheel, another can generate electricity. Dennis |

Replying to: midnightcowboy (Nov 02, 2004 8:27 am) Check your facts. Sanyo doesn't supply HV battery for the Prius. "If the batteries are that reliable then, I wonder why Toyota spent the extra money to make them modular, so they would only have to replace the failing module." Panasonic EV made 7.2V modules to get around licensing lawsuits. Ovonic(I think) only license out NiMH technology to produce small cells. They reserve the right to make large cells for electric vehicle development. One way for Japanese battery manufacturers to get around is to make and sell small modules. Hybrid car manufacturers buy those modules and form a bigger pack. Ability to be able to replace bad modules is a side benefit from that lawsuit loop hole. Dennis |

Replying to: larsb (Nov 02, 2004 8:49 am) Some people do. They would question why anyone would spent extra for green technology, while for them, spending more $$ for performance is perfectly acceptable. They don't care what comes out of the tail pipe if certain type of engines make great low end torque. They question how long the battery pack would last but not how long the oil supply would last. They would question environment impact of the battery pack recycling but not the whole car itself. They don't question spending $$ for bigger and more powerful car either. They don't care realiability of a car as long as the car is more than they are used to. It is sad but true. Dennis |

Replying to: gagrice (Nov 04, 2004 11:05 am) Yup. Ovonic filed the lawsuit anyway. I believe Panasonic EV could of fought it and won but it would delay Prius and other HSD car production. It was the best interest for Toyota to settle it ASAP. Maybe that's how Ovonic took the advantage of the unexpected 04 Prius demand. Dennis |

Replying to: railroadjames (Nov 03, 2004 1:50 pm) I believe that Cailifornia mandated 10 years and 150,000 miles. 8/100K is the Toyota warranty.

Replying to: stevedebi (Nov 12, 2004 12:11 pm) That is the way I understand it. My question is if the car has a problem in CA at 125k miles. Will the State of CA force Toyota to fix it. The car is required to get AT-PZEV rating, that it maintains the same level of emissions for that 10 yr 150k miles. So if the battery or electric motor or ICE dies it will not maintain that emissions level.

Replying to: gagrice (Nov 12, 2004 2:00 pm) Toyota will honor the warranty; it is part of the cost of doing business in California. |
