Global warming and worries about fuel prices have prompted demand for diesel cars and conversions.

This 1965 Chevy Impala was retrofitted to run on biodiesel for MTV's show Pimp My Ride. When it raced a Lamborghini in a quarter-mile drag race, the show's producers were afraid the Lamborghini would win by a large margin, but the biodiesel car dusted it.

The Impala was overhauled by Jonathan Goodwin, a biodiesel conversion specialist and founder of alternative energy start-up SAE Energy. Goodwin specializes in turning muscle cars into eco-friendly machines.
