The whole EV1 situation permanently soured me to their fortitude for this product segment. If the oil companies drop gas back to $2/gallon will the Volt get canceled as Hummer sales pick back up again?
The styling just doesn't work well for me either.
We shall see what real world gas usage ends up being for Volt vs next gen Prius as well.
Hopefully there are viable pure EV cars available when the Volt hits the market so I don't have to compromise with a another hybrid. |

A $40k EV is a bargain. |

My stats.
12,000 miles per year
20 MPG
600 gallons
$4.25 per gal
$2,500 cost per year
$12,750 for 5 years of use.
$20,000 for a new Tesla battery
How much will Volt's replacement be?

GM can't time the failures to all happen 1 mile out of warantee, so any given battery may last much longer. It also is likely to slowly provide less and less electric range, and require more and more gas/E85 to run.
A replacement Volt battery will likely be $10,000 to $15,000. Tesla hasn't announced the cost of their replacement batteries. I'll be suprised if they are less than $30,000.
I'd suggest continuing to drive the Volt until it no longer moves, then scrap it. This would not be pratical with the Tesla, or any other BEV.
So, the Volt is really the "cheapskate's performance EV."

GSP | $10k-$15k is what I heard too.
Tesla is estimating $22k for battery replacement the last I heard, but that isn't the official price.
The Volt battery may seem costly for what you get, given it only gives 40miles/charge (8kWh used but 16kWh battery) compared to Tesla's 220miles (53kWh) (45%-68% of the price for 18% of the range and 15% of the used capacity), but it uses only 50% of its capacity. It uses from 30% charge to 80% charge. This means the battery has extra capacity, so that unlike the Tesla it shouldn't slowly decrease in range, given they can program it to use more of the battery capacity if needed; their 30%-80% charge should also help battery life. The advertised cell life also is a lot longer, at least twice as long in terms of shelf life, and more than 10 times in terms of cycle life.

I also understand from Lyle's posts (over at GM-Volt.com) that even once you have depleted the 30% range the generator can rely on the battery for extra juice if need be.

Some hints of the old Subaru SVX in the design...
Wrap around rectangular tail-lights,
Window glass that drops down into the door,
Sloping rear window with a sudden/flat/tall trunk area,
Slim/sleek headlights, etc...

While the challenges are huge, so are the opportunities. GM, if it follows through with 2010 delivery of Volt, may emerge at the top of the hybrid heap. Designers at General Motors hope to produce a visually appealing car. Volt doesn't look like a hybrid. It doesn't look like a Prius. While not exactly the concept car, the images released do follow sight lines similar to many other American cars. Volt might be considered a hot car. Let's call it the Tesla effect. The high-end Tesla roadster blasted the reputation of electric cars as dowdy, slow, sluggish electric cars of the past. Volt could be considered a sports sedan. Marketing savvy coupled with innovation might bring forth a car America can love. Even if it is good for us!
