SEM History
• Started in 1985
• The Shell Eco Marathon is an energy economy race conducted every year and the primary competitive parameter is minimizing the energy consumption of the vehicle
• 2013-2015 in Rotterdam, Holland. Before that Germany
• 2016 in London, around the old Olympic stadium. Teams from all continents → world championship in fuel economical racing.
• Europe edition 197 teams, >3,000 students from 26 countries

AAU History
• AAU has participated in the race since 2009
• 5 years with two different prototypes
• Since 2014 AAU has participated with the fuel cell power car Cimbre in
the Urban concept category
• In 2014 the team achieved the second place (575 km/L eq) and in 2015
third place (640 km/L eq)
