Team Profile
We, Kaiserslautern Racing Team – KaRaT, are a small Formula Student team from Kaiserslautern that has been developing combustion cars for four years now. This season we build our first electric racer. As we only made it to Silverstone once, in our first season, we are glad to return this year.
As we have no previous experience with electric drive trains we want to start with a basic yet competitive concept. For this reason we chose to use two motors that drive the rear wheels. We’re developing an electric differential but leave out torque vectoring for future seasons. Also all-wheel drive is a future topic for us.
Building an electric race car comes at higher costs than building a combustion car. Thus we reorganized our non-technical department this year and extended our group dealing with sponsor acquisition and care team.
– first electric drivetrain
– team founded in 2007
– second partitipation in FS UK
