The Sierra Club has launched a new website, mocking the Hummer H2 SUV. HummerDinger.com's jabs hit Hummer square in the gas guzzling gut with their satirical stories and Flash movies. The site heralds GM's state-of-the-art 1950s engine technology while the movie highlights Ford's Model T's 25 mpg and H2's measley 10 mpg.

It's fun for the whole family - as long as you're not a Hummer owner or a member of UAW #5.
