I'm still waiting for diesel hybrids to make it on the car scene. I know they are trying this out, but haven't seen any for sale yet.
Steve, it's getting closer everyday. A number of European and Japanese car manufacturers will have biodiesel cars for sale in model year 2010 including M-B, Audi, Nissan, Subaru. Save your nickels and dimes and maybe you can get one of the new Audi R8's with the diesel.

Have to wait and see if biodiesel fuel will be any cheaper that regular diesel or gas. When you blend supply and demand along with greed, it might be too expensive. Might want to hold out for a solar powered electric car.
