I challenge you to a battle of wits, to the death...
About two weeks ago, Elon Musk, the CEO of Tesla Motors, went on Letterman to talk about electric cars and show the Model S electric sedan. It turned out into a kind of electric car good cop/bad cop, with an angry David Letterman ridiculing the Chevy Volt (photos of the Volt here) for its 40 miles range (looked like he didn't understand how a 'range-extended' EV works). Well, Bob Lutz could let that one slip by, so next Wednesday (May 20th) he will appear on the Late Show with GM's Volt demonstration car.

What David Letterman seems to have misunderstood is that the Volt's 40 miles electric range is not the total range of the vehicle. The theory is that since most people drive less than 40 miles in a day, they will do most of their driving in electric mode, without burning gas. When they need to drive a longer distance, a gasoline engine kicks in to recharge the battery (acting as a generator). So total range can be in the same ballpark as regular gasoline cars, but total gas used can be much lower for most people.
At least that's the theory. We'll have to wait and see if the GM Volt delivers, and what kind of real world MPG figures people are getting.
