DUT09

DUT09 The DUT09 design was significantly different from the DUT08. New rules defined minimum dimensions for several cross sections of the monocoque. The monocoque was completely redesigned to meet these new requirements, resulting in a significantly larger cockpit. The spring-damper system was relocated from the top to the bottom of the fore body. Also the ergonomics have been adapted, the steering wheel has been set more vertical and the entire driver position has been improved. Furthermore a backlash free steering system has been installed. All electronic systems have been designed and built by the team itself, including the ECU, Data Acquisition System and load cells in every suspension arm on one side of the car. The car has lightweight LiFePo4 batteries which are 3,5 kilos lighter than the regular lead acid battery. Despite being larger, the DUT09 was 10 kg lighter than its predecessor.

For the third year in a row, the team came second overall in the UK competition (out of over 80 teams), but this time with a tiny margin of 5 points, after a very eventful endurance race on a wet, oily track. A month later in Germany the team was headed for another top 2 position, when a drivetrain component failed with barely 2 laps to go in the endurance. However, the team could still look back on a successful event overall after performing very well in the static events and becoming the first team to win the prestigious Engineering Design event in both the UK and Germany in the same season.
