Interesting, I thought that a diesel-electric hybrid would have much better fuel economy than a gasoline-electric one. But then again, I do recall hearing something about how diesel have a lot of their torque in the low end of the RPM range, just like an electric motor, and so that may have something to do with the less than spectacular mileage. However, a real world improvement (assuming the 318 TD is size and powerwise a comparable car to the Prius) is something to be glad for.
