What is the power consumption of this econo-box and how much does it cost per mile in power consumption and how does that stack up against similarly sized internal combustion cars with greater range and a better price tag? And if one foolishly believes in all this global warming hyperbole, what is this car’s ‘carbon footprint’ after figuring in the carbon generated to supply the power to recharge it’s batteries and how does this compare to it’s peers?

Those are the real questions and the answers would probably shock Joe American if he could get out of his man-cave and quit worrying about Lindsay Lohan and Lebron James long enough to actually do math and learn a little bit of basic science.

Alas, he will just assume it’s better just because it’s electric.

Facts matter not. Perception and willful ignorance is what drives public opinion.

As long as it regenerates its own power. I’ll opt for drilling here for oil. Don’t want to plug some car into the electrical every 100 miles. Ridiculous.

Actually, having one for a second car makes a lot of sense. All those short trips to the store, commuting, etc. I would still have a truck. Got to have a truck.

limited range

Many people do not drive more that 40 miles on the average day. I drove a GM EV1 as my personal car for two years. I seldom drove over 25 miles per day. Of course, we had normal car as the family car.

You have stated a hypothesis as if it were true. What is true is that you are speculating. What was true for me was that it was much cheaper to run my GM EV1.

My electricity cost was 10 cents per kilowatt hour. This gave me an energy cost for my lead-acid EV1 of 2.6 cents per mile. In comparison, my gasoline-powered vehicle that got 22 miles per gallon had an energy cost of 6.82 cents per mile (gasoline cost $1.50 per gallon at the time). I charged by EV1 after midnight when energy cost and usage was low. The energy for charging came from an alternative California Energy Source Company using geothermal energy production.

“You have stated a hypothesis as if it were true.”

I gave an opinion only. I did not claim to be an expert, only skeptical.

I don’t know how your energy cost for your electrical vehicle stacks up against other electric producers, but I’m sure the rates would vary greatly in different locales, but alas, so would the price of gasoline but probably not as much.

Comparing the EV1 to your other car may not be an accurate comparison itself. In the same class as the EV1, gasoline cars can be purchased that easily get 40 mpg. Diesel cars at that size are known to do 50 mpg or better. Both Gas and Diesel have better range, a higher top end and probably accelerate just as well or better.

I’m not saying this car couldn’t serve a useful purpose. If you’re looking at it to replace the Internal Combustion engine, altogether, you would be for the most-part confining yourself to short commutes in the big city. But I guess that’s what Greyhound, Amtrak and our airports are for, right?

Aside from all of that, where is the ROMANCE with a vehicle like that? Unless you’re a real geek, it isn’t there. This car isn’t pretty like a Muscle Car is pretty. Might as well be riding a moped.

Are you old enough to remember those ubiquitous electric carts that old folks used to drive? I think they are no longer street legal. I haven't seen one in decades. But our elderly next door neighbors had one for runs to the local supermarket. It was extremely practical. There were usually a few of them parked in the supermarket lot. Maybe I can find a picture of one.

That is still 3.75 cents per mile as compared to the EV1's 2.6 cents per mile.

Both Gas and Diesel have better range

My original post pointed out that many people do not drive more than 40 miles per day. A range of million miles would not do anything for them.

a higher top end and probably accelerate just as well or better.

A EV1 set a land speed record of 183 mph. It would accelerate from 0 to 60 in 8 seconds.

Aside from all of that, where is the ROMANCE with a vehicle like that?

I really do miss the babes that would wave and try to talk to me at stop light. I miss the people who would come up and talk to me about the car when I parked somewhere. The EV1 was a very attractive car.

I charged by EV1 after midnight when energy cost and usage was low.

The problem with this scenario comes when a significant number of people have EV's and everyone decides to charge at night when the energy costs and usage is low. Suddenly, energy costs during that time frame will spike, usage will spike and the utility will find itself having to scramble for periods of low usage time to do routine maintenance. No greenie I've ever heard ever acknowledges this simple fact. There is no free lunch.....

This is just wrong. This is based on commute distance. However most people don’t just go to work and home. On weekends they drive more than 40 miles. After work they may drive more than 40 miles. It is not practical to have a car with limited mileage. You would have to change cars whenever you wanted to go 41 miles. This is crazy talk...

The other problem nobody wants to deal with is the drop in range when accessories, specifically heat, lights and AC are in use. I'm right on the cusp of the 40 mile range for home-work round trips. But i live near Chicago and as they say if you don't like Chicago weather, wait five minutes it will change. I have had my 18 mile commute go to 4 hours due to snow or when flooding closed many of the streets. In the winter you have to run the heat constantly or the windows Ice up or fog over. In the summer it can get into the high 90s and AC becomes a must unless you want to get to where you are going pit stained and stinky. And the day can start out nice and temperate, and then hit you with a blizzard or heat wave while you are at work. I need a car I can count on to get me home. An electric car with half a battery charge (you used the first half getting to work) isn't going to cut it.

The way i look at it my current car (Mazda M6) Averages just under 25 miles to the gallon with my average driving. So in theory I could get to work and back with only two gallons of gas. But would you buy a car with a two gallon gas tank knowing that if you hit snow, rain, extreme heat, or just really bad traffic you would end up out of gas on the side of the road. I just don't need that kind of stress.

Thank you.

Simple operational characteristics of a compact car:

Range: 375 miles
Speed: >90MPH
Passengers: 4 (incl. driver)
Air Conditioning: Yes, does not significantly affect range
Heat: Yes, does not significantly affect range
Cargo: Yes
Recharge time: <5 min

That's what electric cars are competing with.

What!?! Lucas wiring is troublesome?? /s

I have no idea how much of that VW/Bradley GT wiring remained in this electric conversion. I was thinking just in ease of working in the engine compartment. That GT6, the whole bonnet tilts off, like it’s Jag big brother, for complete access.

I’ve seen GM small block conversions of that GT6. Lot’s of fun.

BTW I bought one many years ago that a guy was using as a dog house.
It took almost a year to get it ship shape.

No, it is not based on commute distance. It is based upon miles driven per day which includes commute distance. My EV1 had a range 75 miles pr charge. I had plenty of spare miles to handle most deviations from the norm.

When electric cars become ubiquitous, there will be charging stations all over the place. There were numerous free (!) charging stations in my area when I had my EV1.

That's a basic outline of what my Corolla will do. Similar offerings from Honda, Hyundai, Ford, etc. have similar capabilities. They have to, or they wouldn't sell.

Do you think any of those capablilites are incorrect? If so, please provide the basis for such thinking.

Just because many cars will meet those specs does not mean that the average person needs a car with those specs. That is like saying that average fast food meal has a 1000 calories thus everyone must have 1000 calories per meal. How many places in the USA are there where you can legally drive over 90 miles per hour. How many people need to drive less than 40 miles per day? How much cargo does average person need?

(My EV1 had more than double the cargo space of my Miata. My EV1 had excellent air conditioning and heating. It had a feature that would allow the car to be pre-heated or pre-cooled while still on shore power.)

Yeah, you're right. If Lucas Electronics were buggy, they would give it a clever nickname, like the Prince of Darkness.

If I ever free up the time to do an auto restoration, a GT6 would be high on my list of possible projects (competing with the early versions of a Bronco, Scout, or Falcon, a GPW, or a TR7 (have to admit, I always loved the wedge)).

Irrelevant. Miata is in a whole different market from Corolla, Civic, etc.

My EV1 had excellent air conditioning and heating

Did the use of those, while moving, significantly affect its range?

It had a feature that would allow the car to be pre-heated or pre-cooled while still on shore power.)

How well did this feature work when the car was moving? How many minutes did the pre-heat or pre-cool last?

How much cargo does average person need?

A big load of groceries. Two or three suitcases and a couple of small bags. What do you think?

How many places in the USA are there where you can legally drive over 90 miles per hour.

Irrelevant. The actual top speed is much higher than the legal limit. Thus, traveling the legal limit (or a bit over) is not running the car at maximum performance. That's a good thing, if you want it to last.

Just because many cars will meet those specs does not mean that the average person needs a car with those specs.

Again, the specs significantly exceed normal operation. Thus, normal operation does not stress the system, and abnormal circumstances do not exceed the systems capabilities.

How 'bout that <5 minute recharge time?

Standard performance cars are designed to meet the needs of the average driver in the target country. The free market is, among other things, a great way of determining what people want and need. Toyota, Honda, Hyundai, Ford have used the (mostly) free market to determine what sort car the "average American" wants. The Corolla is a prime example.

Electric car designers should recognize that the Corolla/Civic/Focus/Accent/etc illustrate the performance envelope that the "average American" wants. If they want to sell cars, they know what they need to produce.

You may have been very fond of your EV1. That doesn't mean its capabilities are within the desired/required performance envelope.

In Illinois (and I'm fairly sure everyplace else) there is no such thing as free. Just stuff Mayor for Life Daley makes other people pay for. I don't want to give that SOB another way to get into my pocket. I know the electrics have a place, but at the moment I don't see one of them being in places that get heavy snow. The combination of 2-3 times normal commute time combined with running the heater would simply be doom given existing battery technology. Now my wife who has a <2 mile commute would probably fit perfectly into the EV market.

The other problem is time to charge. According to the EV1 fan site http://www.ev1.pair.com/charge_across_america
The first generation lead-acid batteries can be recharged from 20% to 80% capacity in approx. 45 min. with the 220 volt 6.6kW charger. A complete 100% charge takes about 3 hours. These times are approximately double for NiMH batteries. The 110 volt 1.2kW convenience charger is much slower, replenishing approximately 8% per hour or 15 hours for a complete charge. A new 50kw Fast Charger has been developed that will recharge from 20% to 80% capacity in 10-15 minutes.

A 3 hour fill up doesn't seem like a lot of fun. Even a 10-15 minute stop a one of the high capacity chargers seems a bit excessive. If you assume charging stations will function like gas stations the problem becomes obvious. I often have to wait for an open pump. Not a problem if it only takes 5 minutes for a fill up, most I waste is 10 minutes. But if a fill up takes 15 minutes and I'm not the first person in line I'm out half an hour.

If you drive an electric car then you will accept some limitations just like if you drive a Miata, Hummers or many other cars. If those imitations can fit in with your life style then they will not cause you problems. If you can not accept the limitations then you need to find a different solution for your situation. Many, many people can live with limitations of electric vehicles, Miatas or Hummers.

Land Speed Record? I doubt 183 MPH is the ‘land speed record.’I think the records are much higher than that and I’m certain the vehicle was heavily modified and I doubt it can do it with it’s powerplant for more than a very short period of time, anyway. Minutes maybe. Seconds, most likely. 0 to 60 in 8 seconds, I might buy that, but I believe even a decently equipped Pontiac Fiero could do that.

You live with a claim of superiority in ideal (unreal, for most, actually) economic conditions that support your narrative. A bit of confirmation bias, methinks. I pointed out internal combustion engines in the same class that do comparably, if not better when we talk especially about Diesel in specific. If the EV1 were a marketable alternative, GM wouldn’t have called them all back and crushed them.

You fail also to take into account how much electricity demand would go up and hence the price of the electricity if a good percentage of folks owned an electric car and the negative consequences to other energy requirements that require electricity, like say, lights in your house, factories that make stuff, and heat in a good number of homes. This has happened with other alternative forms of energy. It is known that increased Ethanol usage had a negative impact on food prices and arguably caused hunger in some parts of the world, like Mexico. Those kinds of things.

Like I said, I’m not saying it couldn’t serve some useful purpose economic or otherwise for someone, somewhere. I’m just saying there is no way within the next 20 years that even a plurality of us will be driving them.

If you like it fine. Since only a few of the ugly ducklings existed, of course it catches the eye. If even 1 of 10 people had one, it would cease to be a conversation piece but if you think it made you a chick magnet, I am not one to frown on you for having self esteem.

> My electricity cost was 10 cents per kilowatt hour. This gave me an energy cost for my lead-acid EV1 of 2.6 cents per mile.

This is a bit misleading. As anybody who understands rechargeable battery technology can tell you, the major cost factor with batteries is the fairly short service life and the high replacement cost of the batteries themselves, not the cost of electricity.

The initial lead-acid battery pack for the EV1 stored 16.5KW/h and had an expected total service life of about 7000 KW/h before it would need to be replaced. Therefore, it could only store and deliver about $700 worth of electricity. I have not been able to find exact numbers on the replacement cost of the 1.5 ton battery, but it was probably over $4000. Therefore, the recurring cost of the battery replacement would probably have been about 15 cents per mile. Ouch.

The second-generation nickel-hydride battery pack for the EV1 could had a capacity over 25KW/h, and had a service life of around 24,000 KW/h, but the replacement cost of the NiMH battery would probably have been over $12,000 - so the battery cost-per-mile would still be about 14 or 15 cents.

There is a company called Ceramatec which claims to be able to deliver a sodium/sulfur battery which will have a lifetime battery cost of only 3 cents per KW/h delivered. However, the characteristics of the battery are not an ideal match for an electric car.

Personally, I believe that an electric car would be practical if it used a zinc/air fuel cell instead of a battery pack and included a small 15hp Wankel engine/generator and a 3 gallon gas tank as an emergency range-extender.

The Wankel was low on efficiency but that may not be a problem with limited use as you suggest. I always liked the Wankel.

Yes, early Wankel’s got poor gas mileage. However, it did improve over time. The idea here would be to allow the car to be used even in areas where there are no ‘zinc fill-up’ stations without the risk of getting stranded. A gasoline-powered range of about 100 miles lets you cross just about anywhere.

Wankel engines have the highest power/weight ratio of standard internal combustion engines, and I think I read that they could be built with internal magnets and coils to function as an integrated motor/generator.

They are within the required performance envelope of millions of people.

Are they?

Where are the millions of people clamouring to buy them?

Please don't take this personally. I'm not insulting you, nor am I insulting electric cars.

I'm pointing out an objective measure of what sort of performance people actually want/need, based on what they buy. If the designers and builders of electric cars want to sell millions of cars, to be a major player in the market, that's the kind of performance they need to put on the showroom floor.

The EV1 was an interesting experiment, establishing a baseline measure of "production" electric car performance. It was also carried out more than 10 years ago. Battery technology and motor technology have improved since then, and the wide acceptance of hybrid cars will support continued improvements in both. I'd be interested in seeing how an "EV2", using 2010 rather than 1999 technology, would perform. I'm sure it would be closer to the Corolla/Civic/Focus/etc performance envelope. I think I can also predict its weaknesses.

BTW, I asked some questions in my last post. They were meant to be information-seeking, not combative. Would you please be so kind as to address them?

They are for thinking people.

Yep, when the facts don't go your way, attack the messenger. Weak. FYI, I hold an MSEE from Georgia Tech. ('87) Care to share your background and education?
