Herndon, Virginia – Two Audi A3 TDI models have completed a 1,000-mile (1,600-kilometre) event on clean-burning synthetic diesel. The endurance drive, part of the 2010 Green Car of the Year Tour, spanned the length of California.

The tour, a partnership of Audi and the Green Car Journal, used RenDiesel, a synthetic fuel produced by Colorado-based Rentech Inc. The tour began in Eureka, California on October 18.

“The benefits of modern clean diesels like the Audi A3 TDI are apparent on many levels, from improved environmental performance to providing the kind of driving performance people expect,” said Ron Cogan, editor and publisher of the Green Car Journal. “Operating on advanced, clean-burning fuels like synthetic RenDiesel simply makes the diesel equation even more compelling.”

The RenDiesel used on the tour was made from natural gas at Rentech’s demonstration plant in Colorado; it can also be made from synthetic gas produced from biomass and waste resources. The fuel is expected to be produced in commercial quantities from green waste and other organic materials at the company’s new project in Rialto, California.
