We look to the day.

Bring it on.

“Why did GM change the orignial concept look to a prius look?”

They needed better aerodynamics to achieve the 40 mile range on the highway.. the original concept was also too masculine and ugly.. half of all car purchases are decided on a woman’s opinion.. perhaps more.

“Why is Karma using the same powerplant concept GM is for the volt and the karma car looks better than the volt and it gets 10mpec (miles per electric charge) more than the volt?”

No idea, perhaps they are using a bigger battery, perhaps they are discharging the battery deeper at the expense of a shorter life.

“So I purchase a volt, what happens when I fill the tank with gas and then never uses the fuel because I drive less than 20 miles per day with recharge every night?”

GM has stated no additives will be needed.. we have guessed the Volt will use a bladder type gas tank like the Prius.. thus the gas will never be exposed to air. If you need to run the engine for peace of mind, just skip charging the battery for a couple of days. The computer may also periodically start the engine anyways. You should also use a “Top Tier” gasoline such as Shell or Chevron to make sure your injectors are not clogged.

“Will GM have more choices in fuel for the backup engine other than Gas? Biofuel, hydrogen, diesel, Propane or Natural Gas?”

I believe E85 will be ok..

” (Natural Gas would be a better equiv. because it won’t clog up or go bad like Gasoline. It could also be generated from a household NG compressor (CNG) in the garage. http://www.fuelmaker.com)”

The Phil is very expensive, and requires expensive rebuilds every three year.. 78% of the public will never need the range extender during their daily commute, thus spending a lot of money on it does not make sense.

“So the Prius replacement batteries cost over 300.00 to replace, what is going to be the cost of the volt’s replacements?”

Prius battery is around $2500 new, much less from a junkyard. LG charges GM around $8000 per each battery, GM installs in the battery box with added electronics.. so perhaps a replacement pack will be $10-$20k, no idea, probably GM does not know either. Battery warranty will be 10 years/150k miles.. hopefully by that time you should be able to buy aftermarket batteries much cheaper.

“Will they have an exchange program to bring the cost down?”

There will be a heavy demand for used batteries, from many people..

So, I take it that they are going to run on air. Blow you away!
