Delft University of Technology Racing Team<br />

14<br />

The Delft University of Technology Racing Team consists of 80 team<br />

members from eight different faculties of the university. After building ten<br />

combustion cars the team decided to start building lightweight electric<br />

cars. The team is divided into 5 technical departments and a management-team consisting of 4 people. The<br />

newest car, the DUT14, can be described as an extremely lightweight four-wheel driven electric car<br />

enhanced with aerodynamic devices, a slip ratio controller and a yaw rate controller. All four motors are<br />

placed inside the wheels together with a one-stage planetary transmission. With the self-designed tyres the<br />

team was able to fully optimize the wheel assembly and improve tyre behaviour. This year, aluminium<br />

honeycomb is used as core material for the composite monocoque, reducing the weight of the chassis.<br />

Based on wind tunnel tests and CFD calculations, 725 N of downforce at 60 km/h is achieved with a rear<br />

wing, front wing, and diffuser.<br />
