The "eleven-four", first car of the Rennteam with a carbon fiber monocoque, could continue the streak of success of its precursors. Due to the fundamental change of the frame concept the competitiveness was difficult to assess, however the "eleven-four" rejected all doubts at the Formula Student UK at Silverstone Circuit, which we won in spite of difficult weather conditions.
After the failure at Hockenheim the year before the objective of 2009 was to win. The probably strongest field of competitors on European ground could not keep up with the "eleven-four" and the Rennteam won the Formula Student Germany clearly.
"Hat trick" in Italy: The high expectations after the two victories could be fully met. The victory of the Formula SAE Italy was not only the third victory in three contests for the "eleven-four", but also the third victory of the Rennteam in Italy in a row.
Since this season has been very successful so far, the Rennteam decided to compete in the biggest Formula SAE competition in Michigan in May 2010. Hopefully this final challenge of the "eleven-four" with the rest of the world will be as successful as the others were.
