Hybrids aren't actually the greenest way to get around Hollywood -- a fact George Clooney can attest to. It's the electric Tesla Roadster, which has zero tailpipe emissions and doesn't take gas. But it's not just eco-friendly -- the $100,000 Roadster is a real sports car. This baby goes from 0 to 60 in an astounding 3.9 seconds. (Compare that to a Ferrari Enzo's 3.4 seconds.) Not bad for a car that plugs into the wall at night. George owned a 2008 model until earlier this year, when he auctioned it off to raise money for Sudan.
