This document summarizes the Umicore Electra team's involvement with the Shell Eco Marathon competition over several years. It discusses their partnership with Umicore starting in 2013, their results in the 2014 and 2015 competitions, and their plans for improvements to compete in 2016 and 2017. Their best result was in 2015 when they achieved a fuel efficiency of 121 km/kWh, equivalent to 0.1 L/100km, placing them 5th in their category. They have undertaken student projects to develop new front and rear suspension systems, and have plans to test new components like motors, wheels, and gearing to further improve performance. Their goal is to develop a new vehicle for 2017 that will be lighter, more efficient, and

6. Shell Eco Marathon
Competition
Shell Eco Marathon 2014:
Shell Eco Marathon 2015:
 Major failure of the front shafts  Unable to finish the race  first
time over a decade without result !!!
 Need for reliability !!!
 New concepts of front and rear axles for 2017 (students projects)
 No problem detected  the vehicle is reliable !
 Best result achieved :
121 km/kwh  0,1 l/100 km (best result for the Ulg team ever !!!)
5th position of our category BUT first without solar panels

7. Mechanical Integrated Project 2014-2015
Goal: Suspension system on both the front and the rear axle
Achieved System: Manufacture of a prototype for both mechanism
Pending works: Validation, improvement and final design before manufacturing
