California Governor Arnold Schwarzenegger was so impressed by the biodiesel makeover he took part in on an upcoming environmentally-themed Pimp My Ride show, he insisted mechanics install the same engine under the bonnet of his Hummer.

The star and rapper/host Xzibit joined forces to makeover a 1965 Chevy Impala and give the classic vehicle an environmental, biodiesel edge as part of an Earth Day Pimp My Ride.

And Schwarzenegger was stunned when Galpin Auto Sports mechanics fitted the classic car with an 800 horsepower biofuel engine, equipped with recycled plastic bottles. He has now asked Galpin boss Beau Boeckman to fit the same engine in his own car.
