Info
Who are we? The Rennteam Uni Stuttgart was founded in 2005 and has since built up an impressive history in Formula Student. What are we planning to do this season? Besides the switch to a new tire size we developed a plug and play hybrid system, which marks a big step in our history. Since it will be the last year combustion vehicles are allowed to participate at FSG we tried to maximize our performance on track. But trust us, it won't be the last time you will see the Rennteam in action. ;)

Info
Since the foundation in 2005 one of the most important reasons for success of Rennteam Uni Stuttgart was to set clear goals and milestones right from the beginning of the development of every new car. Get the car done in time. Finish the endurance and win the competition. The long period of intensive car testing ensures a reliable and powerful racecar. The concept is a lightweight 10” wheeled car with a powerful 4 Cylinder Honda CBR engine. The CFRP Monocoque with a tubular space frame rear was chosen to improve accessibility and maintenance of the entire powertrain. Through optimization our wings guarantee a well balanced aerodynamic package with maximized efficiency, regarding downforce to drag ratio. Looking forward to meeting the international competition, the team is excited for the Formula Student Germany Event 2013. We will try our best to defeat our overall victory from 2012. Thanks to all our sponsors who gave us the opportunity to build the F0711-8.

Info
Since the foundation in 2005 one of the most important reasons for success of Rennteam Uni Stuttgart was to set clear goals right from the beginning of development of every new car. By having the focus on completing the car as fast as possible the aims of finishing the endurance and winning the competition complete the three major goals in development of the F0711-6. The long period of intensive car testing ensures a reliable and powerful racecar. In order to reduce both, weight and fuel consumption, several new concepts have been implemented. The CFRP Monocoque with a tubular space frame rear was chosen to improve accessibility and maintenance of the entire power train. Every detail of the suspension system was redesigned resulting in further weight reduction. With the F0711-6 the Rennteam has once more managed to build a competitive car. Looking forward to meeting the international competition, the team is excited for the Formula Student Germany Event 2011.

Car #1
Info
Right from the beginning of building our first race car we worked according to some basic principles. Set clear goals and milestones. Get the car done in time. Finish the endurance and win the competition.Keeping the time schedule tight allows us to have the first test run in the middle of April. So our 2010 car, the F0711-5, was actually tested for more than two months before it took part at the first competition. Our technical goals for the F0711-5 have been to reduce weight of our CFRP monocoque and to improve our engine design to save fuel and to have higher torque at lower rpms. The self built 4 speed gear box improves drivability and a strict lightweight design forced every detailed part to raise performance. So we are really looking forward to be competitive again and to be able to repeat last year’s success. Thanks to all our sponsors who gave us the opportunity to compete at FSG once more. We will try our best to defeat our overall victory from 2009.

Car #29
Info
From the beginning of the existence of our team we worked according to some basic principles. One of them is that we set clear goals at the beginning of a season. Our goals for this year are: get the car done in time - finish - win. Especially the first point is important to be able to have a competitive car at the competitions. The first test run of our 2009-car, the F0711-4, was at the end of April. So we could test it for more than two months before we took it to the first competition. The biggest change this year is that we built a CFRP-Monocoque instead of a spaceframe. The monocoque gave us more freedom in designing the suspension kinematics and higher stiffness. We also optimized our engine design to save fuel and to have higher torque at low rpms. Of course we also tried to optimize every detail of the car to be very competitive again and to have a good chance to win this year.

Info
The Rennteam Uni Stuttgart competes its 3rd year in Formula Student Germany. After being the best German team 2006, the team finished 1st Overall in 2007. The second-year car "F0711-2B" started in three other Formula SAE Events, bringing home impressive results: Silverstone: 3rd place. Italy: 1st place. Michigan, USA: 2nd place. The "F0711-2B" therefore was a solid basis for designing the new car. In fact, most of our team members were satisfied with the existing solutions and therefore took a year off instead of working hard on improving an outstanding racing car. We just made little adjustments like a dry sump oil supply or carbon fibre rims. After that the car was sent out on the track for fitness improvements with two main goals: Reduce weight and gain power.The result is amazing: The achieved weight reduction adds up to 15 per cent whereas the engine power was increased by 13 per cent. The "F0711-3" is looking forward to meeting its competitors, burning a lot of fuel and rubber.
