ELECTRONIC SYSTEMS AND COST OPTIMIZATION in lower development costs and enhanced development quality.” DaimlerChrysler’s perspective on the delicate balance between legislation and customer requirements was presented by Dr.-Ing. Leopold Mikulic, Director of Development Passenger Car Engines & Drivetrain DaimlerChrysler AG. Taking into consideration the demands of the market and legislation for highvalue technologies, he named the following “important factors in successful cost optimization”: - Modular concepts with favorably priced basic units - Adjusted choice of sustainable technologies to achieve objectives - Development of technological strategies taking various environmental scenarios into account. Heribert Scherer of ZF Getriebe GmbH presented the new step automatic transmission range of ZF. He had prepared his paper on “The ZF 6-speed automatic transmission range - A contribution to increased customer benefits, preservation of resources and reduction of environmental impacts at minimum efforts” together with Dr. Gerhard Wagner. Scherer stressed: “With the transmission system and design measures, the number of components was reduced by 30 %, the space requirement by approx. 6 % and weight by some 15 %. The production time of the 6-speed transmissions has been cut back by some 40 %. The fuel consumption with these transmissions has been reduced by about 5 %, while acceleration has also been improved.” The presentation of Dipl.-Ing. Günter Alberter, Head of Development Chassis & Transmission at Continental Temic revolved around system integration as a “key to enhanced customer benefit and reduced total cost”. He came to the following conclusion: “Simplified mechanical systems and/or components gain added value through intelligent controls. (...) New systems or components can only fully realize their potential if they are intelligently interconnected with existing systems.” / 20 2005 Modern Powertrain Systems: High-Tech – Low-Cost. A Contradiction? Finding the balance between technological innovations and cost squeeze was the topic of the “Engine & Environment” conference 2005. Against a background of growing customer demand for “vehicles below 10,000 Euros”, Philippe Boudinot (Economic Manager of Logan Program) and Alain Vignaud (Vice President Conception and Technology Powertrain at Renault) gave a presentation on “Logan and market-driven engineering: How powertrain systems contributed to meeting the cost challenge of the project”. The other side of the automotive spectrum was presented by Dipl.-Ing. Richard Bauder, Head of Diesel Engine Development at Audi, who presented the Audi-V diesel engine family (V6-V8-V10). Summarizing his talk, Dipl.-Ing. Bauder said: “The uniform base engine concept for all Vengines is modular and so flexible that the highest technologies can be implemented without compromises at reasonable cost. The high proportion of identical and synergy parts reduces the time needed for development, which in turn results Left: The conference participants at the reception in the extended and newly opened AVL headquarters in Graz.
