cj,

If I were to guess, batteries. Apparently that is the big risk factor in the Volt, they are not sure the battery will be available for a 2010 launch.

The batteries are still under development, but the problem is not that they will not have batteries (they already have prototypes), the problem is that they will not meet the full spec that GM is expecting.

With the big cars, you just multiply everything by 2x (if that's the weight ratio). Other than that, there is a lot more room to store the batteries, and the profit margins are high enough to sell these at profit.

But the biggest benefit is in terms of gas consumption. A regular gas powered little gas powered car may use up 1,000 gallons of gassoline per yer. You may cut that with combination of plug in electricity and onboard engine to anywhere to 500 gallons or way below possibly even 100 or below. So you may save 500 to 900 gallons of gas.

Now, multiply that by 2 and you save 1000 to 1800 gallons of gasoline. And another benefit is that GM would probably increase the sales from these cash cows, even with high gas prices...
