Bjorn,
I always appreciate your input even if it is sometimes... inflammatory (might not be the right word) towards the hybrid people. Anyway, regarding the diesel-hybrid, you might be right, it might not be cost-effective. Perhaps it could be a primarily electric-driven PZEV, while the diesel engine was designed less for torque. The engine could be for charging the batteries and highway cruising only, while the electric motors were for accelleration and most of the driving. Perhaps it could have cylinder management like the Hondas or Dodge Magnum??? I dunno.
