Team Description
KTH Formula Student is a project where we design, manufacture, test and compete with a car in Formula Student. The project is all about learning to work as a team and produce a high quality product together. The experiences gained from the year long project provides the members with a head start in the transit between academic studies and the future workplace.
KTH Formula Student was founded 2003 by Dr. Fredrik Westin, former PhD student at KTH. Since then we have competed continuously in Formula Student competitions. Today, the team consists of around 80 students from different educational programs and phases at KTH.

Info
Built upon lessons learnt from Dev17, KTH Formula Student is now back with its next generation human- and autonomous-driven racecar, Dev18. A completely new aero package, combined with refined power delivery system and driver aids that allows for better grip and performance both in driver and driverless mode. With our biggest and strongest team to date we are confident to push our own and formula student boundaries' further.

Info
Driven by our core values: innovation, challenge, and teamwork, KTH Formula Student has developed a unique racecar, which is a complete redesign from the previous generations of cars. Not only the looks but also the innovation implemented in the DEv17 means that we are proud to present our first 4wd car with our first carbon fiber monocoque in over a decade! On completing the first generation of this car, the team will focus on improving this concept in the future, as still a lot can be learned!
Engineering Design Priorities:
Carbon fibre monocoque
3x decoupled heave/roll
LV hardware architecture
4WD with hub motors
Ground effect aeropackage

2012
Info
This season KTH Racing, the FS-team of the Royal Institute of Technology Stockholm, designed and engineered its 9th car so far, the R9e. The highly motivated and multinational team from all levels of university education decided to completely start from scratch to set a sustainable basis for the next years. The design goals of the R9e were an agile and easy-to-drive racing car, which was achieved by a low inertia and a low centre of gravity. Contrary to the last year, the electric drivetrain is driven by two AC motors, that deliver 85kW peak power. The purchased build-in motors are integrated in a fully self-developed motor housing that is attached to a self-developed two stage gear box. The powertrain represents a fully integrated and lightweight unit delivering independent torques to each of the rear wheel, managed by a torque vectoring system. KTH Racing want to thank all sponsors and collaborators and is looking forward to having a successful competition on Hockenheim this summer.

2011
Info
KTH Racing was founded in 2003 and has built one car per year since then, focusing on the European FS competitions. This year we have a highly motivated multinational team of around 30 students from all 3 levels of university education. Our aim in the concept ideation of our newest car, the KTH R8e, was to have medium power in a low-to-medium weight car to make it both maneuverable and efficient. In the design of specific parts we strive to make them as simple and robust as possible, with the goal to ease manufacturing and servicing as much as possible. What makes our car stand out is the fact that the chassis is built in a modular way to allow us to switch out its rear part in a matter of hours. This added flexibility allows us to run the car as either a internal combustion engine car or an electric car. In this competition we are focusing on the latter application, as we make our debut into the electric class of FS.
