They have promised that batteries will last 100,000 miles before a reduction in performance. After that you will see reduced performance but they will be functional. Researchers believe battery capacity can be doubled or tripled based on current technology not counting nano engineering and new air anodes. Within a decade, the cost of a replacement battery will be cheaper than a transmission replacement, engine rebuild and combustion engine maintenance that you require now. Electric is the future

This car uses oil too. If the batteries are dead the GM motor kicks in.

What, and get stuck a hundred miles from anywhere. I will take my oil thank you.

I don’t like hybrids.. you have to go full electric like Tesla so we can stick it to the oil barons

Yes, that is a good point. Though for all their problems, Li-ion batteries are still the best choice given their energy density and superior weight advantage over other battery compositions. This is true for today. As for tomorrow… I don’t know if they will be the best. Engineering the anodes may resolve the issue of not charging/discharging completely. Another possibility is that increased capacity will render that argument moot. Thanks for the civil reply, have a good day.

The problem with litium ion batteries is that you have to carry twice the capacity that will never be used so it can last longer (unlike a cell phone). Other wise, if you use more than 50-70% of its charge all the time, they won’t last 100k miles.

Wow, talking about something really Green~

lol I never drive 300 miles in any given day. The most I ever drive is 15 miles. The EV1 could drive 90 miles between charges and that was with the old style lead acid type batteries. That car was built in the 1990s and since our battery technology has advanced considerably. The reason why we have hybrid cars is because the US is basically owned and ran by the oil business.

Also, they are the future because they are cheaper. Being “green” is not it. They also have more potential for performance than even gas. The limiting factor is battery power. We need a way to charge a car in under 30 min, and not destroy the life of the battery. Also, there actually IS an all electric Sport car; it is call the Tesla, 3.7 sec 0-60 with a 200 mile range when driving calm. Tesla is now profitable, so there IS some demand. It is a very fun car, but it is only fun, not practical.

The problem with an ALL electric car is reality. How are you going to drive 700 miles in your all electric car? Stop every 300 miles for a day? You forget to charge your car and need to go to work in the morning, what do you do? Hybrids let us get the good from both. Since the car runs off an electric motor charged by gas it will be easy to replace that power source with something better in the future, like hydrogen, without a major change that has to happen all at once. Hybrids are the future.
