/ 13 2012 95 – 70 – 50 g CO2/km – Evolution or Revolution? Last year‘s “Engine & Environment” on September 13th and 14th focused on the increasing legislative squeeze on CO2 targets. Axel Eiser, Executive Director Powertrain Development Audi AG, gave the introductory speech. Under the title “Shifts in mobility. Between idealism and realism”, he referred to the waning hype around e-mobility: “Current surveys and press reports illustrate that the hype about electric vehicles is turning into general disappointment and that disillusionment is spreading. (...) Drawbacks, such as high acquisition costs, short range, a lack of charging infrastructure and long charging times are so grave they can scarcely be compensated by the benefits listed.” A major contribution to a break-through of e-mobility “could be made by developing the battery systems further”, as “large packaging space required and their high weight are the main reasons preventing satisfactory ranges.” The forecast of Axel Eiser was: “Even if the share of electrified vehicles were to be 80 percent in 2020, traditional combustion engines would still be used in 80 percent of powertrains (as drives in HEVs/PHEVs or range extenders in EREVS).” Prof. Dr. Uwe Dieter Grebe (AVL Executive Vice President Global Business Development & International Operations, Powertrain Engineering), delivered his keynote speech under the title “CO2 reduction – THE major challenge for the automotive industry” and said that CO2 reduction was a team sport and that all components of the powertrain would have to contribute their share to it. At the end of the conference, Dipl.-Ing. Wolfgang Hall, Director Communality Projects of the BMW Group, introduced the measures taken by the BMW Group to reduce fuel consumption and CO2- emissions, respectively, ranging from the introduction of the Efficient Dynamics strategy in 2007, to the launch of the BMW Active Hybrid models and the BMW i3 and i8 EVs. In his conclusion, Dipl.-Ing. Wolfgang Hall said: “Conventional drives – appropriately developed and optimized – will remain the important backbone of the solution portfolio responding to future fuel consumption requirements, but given their limits, alternatives will also be needed for the near future. These alternatives are primarily electrified powertrains and vehicles, always with accompanying fuel consumption-reducing efforts geared at the total vehicle”.
