The Dubspeed kids go out for a roll in the hay with Mercedes-Benz's diesel E-Class and come back all sweaty about the powerplant, although they don't really say much about the car. Still, they, as does Herr Doktor Zetzche, think diesel's the way to go as far as the perfect balance between performance and economy go. And we have to say, we come down on the side of the KISS-simplicity of a well-cleansed diesel over the technological mishmash of hybrid powertrains. Still, we kinda would've liked to know a bit more about the car.
