GM unveiled the 2011 Chevy Volt this week, and is obviously so hungry for publicity that it even had Bob Lutz, Vice Chairman of Global Product Development, appear on The Colbert Report. It was an odd interview for a show that usually features politicians and writers, but the hook seemed to be Bob Lutz's previous statement that global warming is a crock of expletive deleted. Stephen Colbert, as the (faux) arch-conservative talk show host, suggested that producing the Volt showed that Lutz was giving in to the tree huggers. Lutz stuck by his position on global warming, although modifying it to say he does believe climate change is happening, but he doesn't believe CO2 is the culprit. In the end, Lutz got what he wanted: a quick plug of the Volt's specs. Colbert got what he wanted by getting Lutz to deride hippie chicks.
