The Kaiserslautern Racing Team was founded by students of the technical university of kaiserslautern and the university of applied science of kaiserslautern in 2007. This year we focused on building a more stable electrical system without gaining to much extra weight. The Electronyte e15 has got an aerodynamic kit comprising front and rear wings. It is driven by two self-designed rotary current synchronous motors placed in the back of our carbon fiber monocoque.

The Kaiserslautern Racing Team consists of 34 students from the TU and UAS Kaiserslautern. This year we built our third electric car. It has a carbon-fibre monocoque and is driven by two self-designed electric motors on the rear axle. Our latest innovation is an aero-kit composed of rear wing, front wing and a diffuser. In comparison to last years car we could reduce the weight at 40 kilograms to a total empty weight of 185kg.

The Kaiserslautern Racing Team was founded in 2007 as the team of the Technical University. In 2008 we started with the first first-year car with monocoque at the Formula Student competitions. Since the beginning of 2010 we are also officially working together with the UAS Kaiserslautern. After building four combustion cars we developed our first electric car for last year's competition on basis of the slightly adapted combustion chassis. This year we made a huge step and designed a completely new monocoque and kinematics to be able to deal with the specific problems of an electrically driven car better. The accumulator concept got a little more progressiv and was also completely manufactured by ourselves this year. Our concept furthermore includes several improvements in the two motors that drive the rear wheels as well as in the inverters controlling them and that have been programmed to realize an electric differential.
