/ 26 ELECTRIFICATION/HYBRIDIZATION 2001 Internal Combustion Engine versus Fuel Cell – Potential and Limitations as Automotive Power Sources sel engine is best in class in terms of fuel consumption; further emission reduction is required. (...) The gasoline engine meets the most stringent emission requirements, but its fuel consumption needs to be reduced. (...) During a transition phase, it makes sense from an engineering point of view to pursue hybrid technology solutions; after all the development of important components is also highly useful for the further development of fuel cell technology.” Dr. Uwe Dieter Grebe Potential for optimizing the internal combustion engine and the fuel cell as energy conversion system for vehicle drives were on the agenda of the conference in September 2001. Dr.-Ing. Manfred Fortnagel of DaimlerChrysler held the keynote address, entitled “Internal combustion engines and fuel cells - Potential and limitations as automotive power sources” and summarized the state of development and his assessment of future development as follows: “The dietechnology 2004 In 2004, the focus was on the duel between classic powertrain and hybrid drive. Dr. Takehisa Yaegashi explained Toyota’s hybrid strategy: To limit the costs of the hybrid drive, Toyota opted exclusively for combination with a gasoline engine in the introduction phase. He continued to say that with regard to the diesel engine the costs would increase further given the stricter exhaust regulations in future and that acceptance on the global markets is not given. Hybrid (Opel Powertrain GmbH, since 2012 member of the AVL Executive Board) compared the systems of fuel cell and internal combustion engine and drew the following conclusion: “Combustion engines that are optimized as an overall system together with the powertrain will be the dominant automotive power source in the next 25 years. (...) After successful series launch of the fuel cell, combustion engines and fuel cells will certainly be used in parallel for an extended period of time.” Highly Flexible Classic Powertrain or Hybrid Concept? is a key technology for Toyota and would be expanded to many other applications in future. The head of the department for hybrid drive systems at DaimlerChrysler, Prof. Dipl.-Ing. Karl E. Noreikat, definitely saw potential in the diesel hybrid drive: “The future challenge lies in further reduction of NOx emissions (note: of the diesel engine). Current development shows that hybrid drive systems are necessary from an ecological point of view and feasible Dr. Takehisa Yaegashi, Toyota Motor Corp. from the economic perspective. Thus, the diesel hybrid offers the chance of meeting future requirements.” Manfred Fortnagel, Uwe Dieter Grebe, Bernd Lange, Helmut Tschöke, Peter Prenninger, Theodor Sams Igor Demay, Takehisa Yaegashi, Karl E.
