D e a r R e a d e r,
After the competition in China the season 2013 is now complete – now it`s time to look back. We started with
high goals and expectations into the season 2013. The 36-person team was aware of the risk going along with
the high grade of innovation. The four-wheel-drive, the self-developed control unit and accumulator management, the full-monocoque and the advanced aerodynamics was not to be underestimated.
At first, the season went according to plan. Until the rollout in April the E4 was nearly ready, less than two
weeks later the race car drove its first meters. Indeed we were one of the first Formula Student Electric teams
with a working race car, but the problems did not wait long to come. First the EMC did not work properly,
then software-problems occurred which let the E4 shut down. Due to the complexity it was not always easy to
determine the reason for the problems and eventually we even had to skip the important test event “ZF Race
Camp“ to get fix the car in time for the competition at Silverstone.
Despite a dream start, we could not finish the Formula Student UK as we wanted to - although the 14th place
overall was not that bad. Nevertheless the first endurance failure in the history of the GreenTeam was hard
to take. Even in the most important competition of the season at Hockenheim we did not make it through
the Endurance – which certainly was the saddest moment for the entire team, especially since everyone knew

what potential the car has. This potential could not be obtained because of small things...
In Austria the E4 finally completed all dynamic disciplines except Skid Pad. The 5th place overall gave proof
that the E4 could prevail against the top competitors. For the last European competition in Italy we wanted to
do everything right – and we succeeded. With the Rennteam we achieved a historic double victory. While only
a few days remained before the start of the 2014 season, half of the team was preparing for the competition
in China.
In June we started recruiting for the 2014 season. This early start allowed us to begin working on the new car
already in September. Since then every team member has worked at full speed for the next generation, the
E0711-5. At the same time, the team management has changed. At the same time, the team management has
changed and is officially presented to you in this newsletter.

S P E C I A L:
Saison 2012/2013
One year full of ups and downs
›› STATION 1: Silverstone
In early July the entire team left the European continent towards Silverstone for the Formula Student UK,
the oldest Formula Student competition in Europe. In
bright sunshine the E0711-4 took part in its first competition and recorded its first successes: 1st place in
Acceleration, 2nd place in the Autocross and participation in the Design finals. Sadly in the crucial discipline everything changed: while in only the second
lap of Endurance, the stress-test of Formula Student
competitions, the E0711-4 failed to finish due to a mechanical problem in the steering.
After a long emotional season in 2013, GreenTeam looks back in both sorrow and joy. The whole range from gre-

sign of the E0711-4 was a big challenge for the thirty-six students of the 2012/2013 team. Therefore the rollout of
the car this past April in front of families, friends, and sponsors, was a moment to remember.
The rollout was an important milestone, but nevertheless the car hadn’t driven before this event. Exactly two weeks
after the first revealing of the E4 the car finally drove around the GreenTeam container for the first time. From this
day on, testing was all the team did. Not only the car had to get ready for the competitions, but also the drivers
needed to practice to get a feeling for the car.
Besides testing there are lots of other things to prepare for the competitions, for example planning and calculating
the participation in five events in four months. But not enough: it is not just the fastest car on track that wins a
competition, but it`s the overall concept and execution that is most important. The cost report and design presentations as well as a business plan presentation need to be prepared and practised before the events. To win a
competition, a team needs to be close to perfect in both dynamic and static disciplines.
›› STATION 2: Hockenheim
Only a few weeks later, in early August, it was time for
the highlight of the season: Formula Student Germany.
During the competition which takes place in Hockenheim
the team got to meet many of its sponsors, as well as
many friends and family members who come to cheer for
their rarely seen friends and children. They now could finally take a look at what the team achieved during many
day and night shifts in the container and while testing the
car.
Unfortunately, problems hit the car again at Hockenheim
and the E0711-4 was only able to take part in the Autocross and Endurance dynamic events, where the car was
not able to finish for the 2nd time. After Hockenheim, the
entire team forced themselves to redouble their efforts,
because one thing was certain: The E0711-4 was built to
win. The will and the motivation to prove this fact was to
be demonstrated in Austria and Italy. The expectations
were huge leading into the last two crucial events.

TEAM NEWS:
Testing the limits
First team building activity in a high ropes course
›› Stuttgart.
Shortly after the team was built
and started to meet regularly, the first teambuilding
activity was scheduled. One sunny day in October
we met at the University and went by train to Zuffenhausen where we spent some time conquering
a high ropes course. After a brief safety introduction we could get started. Everyone began in the
practice course, and then we were ready for the lofty heights.
The course was up to eleven meters high. Everyone
climbed at its own pace and was glad when receiving advice from the teammates. As often, from
another perspective things were seen quite differently. We all had fun together and were able to test
our limits.

creatively. These various individual concepts from each
subteam then need to be merged together into a single,
integrated concept which is quite a challenge.
As you can see, the E0711-5 continues to be very interesting as the time frame from design is very ambitious and
tight. Stay tuned for the next part of “Loading - E0711-5” in our next newsletter.

EVENTS:
ETAS Inside Event
The GreenTeam displayed the E0711-3 in Feuerbach
›› Feuerbach. On October 2nd our sponsor ETAS invited seven Formula Student teams to Feuerbach to the ETAS
inside event. The day began with testimonials from ETAS employees, who talked about their work and career at ETAS.
During lunch break, the ETAS associates had the opportunity to get a glimpse of the „Fascination Formula Student“ by
speaking with team members. In the afternoon there was a workshop in which the teams were faced with the task of
building a bridge and a marble run out of old magazines and tape. The results were presented in front of three judges,
who already knew most of the team members from the judging at the Formula Student Germany at Hockenheim. The
day ended with a get-together at the Cannstatter Wasen, which has already become a beloved tradition.
