In celebration of Earth Day, MTV and the Pimp My Ride crew prove that going green can get extreme, especially with a little help from a friend - California Governor Arnold Schwarzenegger.

As part of a very special Earth Day episode airing April 22 at 1 pm ET/PT, Governor Schwarzenegger visits Xzibit, Mad Mike and the entire "Pimp My Ride" crew at G.A.S. (Galpin Auto Sports), as they take aim on a '65 Chevy Impala, and give it a one of a kind ecological alteration.

Ultimately proving that power and preservation can co-exist thanks to partners at Galpin, Imperium Renewables, General Motors and others, the Impala gets an 800 horsepower diesel engine that will run on biodiesel, turning it into one extraordinary clean machine.

"I would like to thank MTV and the entire 'Pimp my Ride' crew for shining the spotlight on the importance of alternative fuels and the fight against global warming. I am very encouraged by the great potential in converting vehicles to run on biodiesel as a way to reduce greenhouse gas emissions," said Governor Schwarzenegger. "I am pleased that the power of MTV's message will reach an audience throughout California and the nation to reinforce the benefits of alternative-fuel vehicles and protecting our environment."

The special episode will air as part of the thinkMTV year-long, 12-step campaign "Break The Addiction" engaging, empowering, and educating millions of young people to make smart, everyday choices that both improve their life and help curb the impact of climate change and preserve the environment.

The episode will also air on MTV2 and MTV Tr3s, and appear on MTV as the kick-off of a "Pimp My Ride" Sneak Peek marathon featuring all new episodes of the MTV hit series beginning at 1 pm ET/PT on Sunday, April 22.
