Chevy Volt

Quite frankly, our local power grid can barely handle it when we all turn our A/C at the same time... So it would have to be seriously upgraded before we can all plug our car in.

This is a common misconception.
First, your supposition that the grid can't handle 'all' of us plugging our cars in, is not a reason for none of us to do so.
I agree that the current grid couldn't handle 100% EVs. However the current grid also couldn't handle the regular demand that will be present in 25 years (which is a guess at how long it would take until the entire light vehicle fleet to switch to EV).
Second, the majority of residential customers will be plugging in at night when there is plenty of spare capacity.
With a smart grid, EVs could even help with high demand times.
 
From some Internet searching, it looks like it will require about 8 KWH to charge one up, over a period of 6.5 hours. That means that the car will draw 1,230 watts -- essentially like a hair dryer.

A room air conditioner draws about 1,000 watts, and a central AC about 2,000-5,000.

The fact that they are charging at night is a big factor. Also, they won't be charging all the way every night.
 
If more and more EVs hit the road, it will be inevitable that we will see more and more variable pricing of energy to encourage charging the cars overnight instead of at 4 PM on a summer afternoon in Texas. But for now a small number won't make much of a dent. And at $41,000 per the target market (greenies with a lot money to put where their mouths are) is rather limited.

The volt is overly expensive; Chevy fails again. Meanwhile Tesla is going to be producing the 2012 Electric Rav 4 for Toyota.

You can get a roadster for a bit more than the Volt. You will also have the ~20k Nissan Leaf and the ~18k Smart Fortwo Electric.

We have to go to a smart grid anyway. I think they are here to stay this time. As a car lover; gas cars aren't going anywhere.

You could watch this, even though it is about a hydrogen; what Jay Leno has to say is pretty awesome: YouTube - Honda Clarity (Runs on Hydrogen and exhausts H2o)
 
I really like Jay Leno's garage. He reviewed the Telsa too sometime back.

The Leaf would be a nice car for short errands. But 50 miles one way is too short until their are more charging stations around.

Just read recently that Honda decided to drop diesels and focus on Hybrids.

I'm a little skeptical about that number of 8KwH. If 100% efficient, that would nominally let you run the car at 8KW for an hour. 8KW is 11HP. The car looks like a standard mid-range sedan to me, the kind that would have a 1.8-litre 140HP engine in Europe and a 2.7-litre V6 (with not much more power) in the US. At 11HP it would be going about 25mph for an hour. At highway speeds I've give it about 8 minutes.
 
I'm a little skeptical about that number of 8KwH...
My understanding is the Volt has a 16KwH battery. However, for battery management to extend the life of the batteries, it is generally only discharged down to about 40% and only filled to about 90%.
I will be very interested to see the real life electric range as well as the mileage when in charge sustaining mode.
 
I think for a purely EV (I'm talking something like the Leaf, not Volt) what would be acceptable is as many charging stations as gas stations, a 250 mile range and a 10 minute recharge time. That's if the EV was used like a regular car.

On the other hand, as a second car, just to go and get groceries, something like the Leaf is tempting.
 
And at $41,000 per the target market (greenies with a lot money to put where their mouths are) is rather limited.

At that price, you could buy a Honda Insight hybrid (which looks similar and gets about 40 mpg), for about $20k, then use the additional $21k to buy 7000 gallons of gas at $3.00 per gallon, which would last you roughly 280,000 miles, or almost certainly more than the life of the car. And that doesn't even account for the gas the Volt will use to go more than 40 miles or the cost of the electricity to charge the battery. I don't see many sales at this price.
 
I am curious how well the hybrid and fully electric vehicles handle extreme cold conditions (40 below zero). I have my doubts about how well they would work in those situations.

The 8KW number is consistent. Like you say, 11HP for an hour, and they only claim 40 mile range in EV mode). A car that size, on average only uses about 11HP.

The flaw in your analysis is that a 140 HP conventional ICE car rarely ever produces 140 HP (only for an instant during hard acceleration at the peak of the torque/RPM curve, and then it's time to shift again). The torque/RPM curve of an electric motor means you don't need 140HP for acceleration, all those ponies in an ICE are to compensate for the lack of low end torque. An electric motor has max torque at stall (0 RPM).


For reference, the Tesla Roadster gets about 225 miles on 55KW. At 55mph, that's about 4 hours of driving, or 13.5 KW continuous, or about 18 HP (100% eff for simplicity) in a high end performance sports car.

I don't see many sales at this price.

People will buy them to make a statement. I also don't think those are the kind of numbers that work for GM. But it helps them in the 'PR' war - people keep saying, "Why can't GM make a hybrid or an EV, etc, etc." So fine, here you go, want one - $41,000. If you can find a cheaper one, buy it.

25 years for the entire light vehicle fleet? That seems kinda "optimistic." I'd bet we've got a much longer time to work out the power grid issues.

I'm agnostic on the brand & model, but in 4-6 years I'm hoping to buy a three-year-old one from someone who's totally disillusioned with the concept.
 
$41K?

Why would anyone get a volt instead of a prius? Is there something special about the volt that I don't know?

My rule on acquiring new technologies is similar. Let the suckers who have to be the first adapters run in and pay the big bucks while making all of the mistakes. If you wait a bit you will buy a better product for a lot less money.

The week after everyone was standing in line to get their iPhone 4 saw me down at AT&T getting a 3GS for a really nice price. And my phone doesn't have to have an iCondom to get a signal.

But on the EVs I think I will wait quite a while before jumping in. I know you want to tinker with the damn thing, but me, I just want to drive it. And I think there will be a lot of sorting out of all the issues before an EV is cheap enough, reliable enough, and supported well enough before I go shopping.

Meanwhile, I'm shopping for a used 911 Carrera that's 5 or so years-old. Compared to my eleven-year-old 5.6 liter truck, the 25 MPG will be phenomenal - I expect Al Gore to send me a thank you note. In another ten years or so it might be the right time to trade in the Porsche and get a EV. All of you engineer types ought to have it all sorted out by then, and the market place should have prices reasonable as well.

It is Extremely optimistic. I basically used 25 years to give FireDreamers position the strongest 'benifit-of-the-doubt' I could.
I agree, it will most likely take longer:(

I'm with Leonidas on this one. That said the idea of the Volt is very intriguing and I like the concept of most driving being electric, while retaining the longer range of gasoline power when needed. The claimed all-electric 40-mile range almost matches DW's normal driving perfectly.

But the price will have to be cut nearly in half before I'd seriously consider buying one and I'll want to see real-world reliability results for a number of years. And I do believe that the energy density of batteries will get much better and cheaper very soon. The progress being made in that field is rapid and promising.

So while I'm a long way from plunking down any cash for one I'll be watching closely.
 
A 40-mi. range more than covers my average day of driving, but I'm looking at spending about half of $40k on ANY new car...
