General Motors US Marketing Vice President Joel Ewanick drove from Michigan to the Los Angeles auto show in a Chevy Volt. He was rewarded with the Green car of the year award at the end of the press days.

The award is just one of many given to the Volt. But when you have an automobile that creates energy with a new technology you have to have a new miles per gallon rating from the Environmental Protection Agency (EPA).  Instead of one rating, the EPA gave it three:

On electricity alone, the Volt achieves the equivalent of 93 miles per gallon (mpg).
If the Volt creates energy solely from  the gasoline engine, the Volt gets 37 mpg.

If you create energy by combining electricity and gasoline, the Volt generates the equivalent of 60 mpg.

That may not have been everything Chevy wanted, but it does make it best in class for fuel economy against the likes of the Chevy Cruze, Toyota Corolla and the Ford Focus.

Ewanick and I talked on the eve of General Motor’s IPO.

What will be different once the IPO is out?

Ewanick wants to market each brand on it’s on merit. How is that different from years past? Will any of the brands overlap each other?

What does each brand represent?
