International Congress : SIA Powertrain - Versailles 2015

  • 27-28 May 2015


Since the creation of automobiles, their propulsion has been dominated by internal combustion engines, controlled either through spark or compression ignition. However, the last few years have seen the emergence of alternative technologies, mostly based on hybridization or even full electrification of the motive power.
Worldwide environmental concerns have seen more and more stringent CO2 emission regulations and the targets are increasingly difficult to achieve. Similarly, regulation of conventional IC engine pollutants (NOx, PM, HC and CO) has continued to be tightened, both through reduced emissions levels and by the adoption of new test cycles and procedures which are more and more severe.
Whilst important progress can still be made with the spark ignition engine by itself, which has seen significant evolution in the last decade, the key to meeting future challenges will be the successful combination of electrification with IC engine technology. By 2025, it is forecast that internal combustion engines will still power around 90% of the vehicle market, but it is expected that approximately 50% of these will have some level of electrification (Hybridization). Joint development of both thermal and electric vehicle technologies will therefore be decisive to making this large deployment become a reality.

What’s new for this edition?
• New content, more focus
• SIA has decided to merge two successful events
The "Spark Ignition Engine" conference, formerly held in Strasbourg, and the one-day conference dedicated to powertrain electrification, which used to be organized with the support of IFP Energies Nouvelles.
• New recurrence
SIA POWERTRAIN conferences are now the biggest gathering of experts in the powertrain field; there is now an SIA POWERTRAIN conference every year at the end of May (Diesel and Spark Ignition engines, alternately)
• New exciting venue
SIA organization teams always strive to host attendees in the best possible way and we think the famous royal city of Versailles will be the perfect place for this event. Versailles region is also well-known as the prime area for French automotive research and development.

And we improved the key factors of our success
• International representation with more than 400 participants
• Parallel sessions to cover all aspects of the Spark Ignition Powertrain field
• Panel discussion with executive participants from the automotive industry
• Several special moments dedicated to discussions and networking
• Students Forum to make the automotive industry an attractive environment for future engineer
