What is it that has elevated the Stuttgart International Symposium – hosted by the
Research Institute of Automotive Engineering and Vehicle Engines Stuttgart (FKFS) –
to a real can’t-miss event for years now? Is it the broad range of current and important
topics that line the agenda? The expert presentations guiding the way for the future?
Or is it because the event takes place in Stuttgart, the heart of the automotive state,
Baden-Wuerttemberg, and is attended by prominent participants from both the business
and research sectors? The answer is: All of the above!
For the 16th installment of the Conference, I am glad to be assuming patronage for the
event and welcome all the participants and speakers.
This year’s focus topic, “Global products versus non-global requirements”, addresses
the challenges facing both the economy in general and the automobile industry in par-
ticular: What are the consequences resulting from the contrast between global sales
and adaptation to country-specific norms? How can these be overcome?
The Transatlantic Trade and Investment Partnership (TTIP) that is currently being ne-
gotiated between political decision makers in the US and the EU is intended to resolve
exactly these issues, such as this conflict of interests in the automotive sector. One of
the key intentions of this agreement is to standardize the respective national regula-
tions and requirements for products sold globally on both sides of the Atlantic – such
as: side mirrors, blinkers and crash tests – and introduce a unified, high standard of
safety and security. This will lead to the removal of expensive duplicate standards,
which, despite nearly identical safety norms, have up to now required redundant develop-
ment and certification processes. Consumers ultimately stand to benefit once this burden
is lifted. Such a development will likewise be significant for the automotive industry
in Baden-Wuerttemberg – and for the associated machinery, metal and electronic in-
dustries – in that Germany, as an export country, will be able to set the standards ac-
cording to which our worldwide trading partners will have to adapt – not the other
way around! Our high level of precision, reliability, quality and safety together present
a strong sales argument. As such, these high standards should not be weakened in the
course of the TTIP negotiations. The Government of Baden-Wuerttemberg fundamen-
tally supports the TTIP agreement, but also insists that the high safety standards asso-
ciated with products “made in Baden-Wuerttemberg” are not lowered in any way.
I would like to thank all those who have been involved in organizing and executing
this event. I hope that all the attendees will benefit from the exciting discussions,
interesting presentations and also gain new ideas for their own work.

Demands on the automotive industry in terms of research and development are con-
stantly in flux. Producers and suppliers are forced to create global solutions while also
considering individual customer needs as well as the legislative requirements in each
market. Even emissions regulations are anything but unified globally. Starting in Sep-
tember 2017, Europe plans to implement a measurement termed “real-driving emis-
sions” (RDE). Evaluating pollutant emissions will be done on the street rather than at
a testing station, with far-reaching consequences for engine development. Many re-
gions around the globe are, at the same time, calling for localized zones with emis-
sions-free traffic. This all overlaps with the ongoing process of reducing CO2 limits
for vehicle fleets, with all world regions having defined various steps to achieve re-
ductions in this area. This is topped by rising demands in terms of the comfort and
emotionality of cars. How will the automotive industry respond to the growing con-
flict between increasing globalization and maximized global product marketing, on
the one hand, and diverse, particular regional requirements for vehicles, on the other?
What are the technical impacts of this? Industry and research experts will report on
and discuss these issues and many more at the
16th Stuttgart International Symposium for “Automotive and Engine Technology”
on 15 ---- 16 March 2016.
In six parallel sessions with over one hundred presentations, leading experts will ad-
dress the current state of technological development, their most recent research find-
ings, and concepts for the future. The program spans the entire process of vehicle cre-
ation, from research and development through to production. This year, we have also
been able to invite excellent keynote speakers and participants for the subsequent po-
dium discussion. This will be supplemented by numerous opportunities for exchang-
ing ideas, be it in relation to technical discussions, at the accompanying trade exhibi-
tion, or in the social context of breaks and the evening event.
We look forward to seeing you in Stuttgart, the birthplace of the automobile!
