It's more of a legal issue than a technical issue. CARB is trying to expand their authority beyond what was legally set by the Federal Gov't. If that goes unchallenged, then it sticks. Sort of like if your neighbor decides he wants to set up a swing set that extends into your yard and you decide not to challenge it. CARB, California Air Resource Board, has authority to regulate issues directly related to Air Quality. Only the Federal Government can set Fuel Economy standards. This was made clear in the legislation that empowered CARB.

The way that Europe regulates FUEL ECONOMY is to limit CO2 emissions. California Bill AB1493 seeks to limit CO2 emissions. It is a fuel economy bill. Let me remind you that only the Federal Gov't can regulate fuel economy. By the way, GM is not the only manufacturer filing suit against AB 1493. I think that Toyota and Honda are both also part of the suit.

As for the Aveo, yes, GM North America designers have been intimately involved in the design of the product that is sold in North America. It's part of being a global company.
