Ever since 2009 headwind car SPIRIT participates in the Racing Aeolus competition where headwind cars from all around the world compete to be the fastest and most efficient. SPIRIT uses the wind as a power source by aiming a rotor into its direction. Using a chain transfer and a gear box the movement is transferred to the wheel axle which makes the car move forward.
During its first participation in the Racing Aeolus competition in 20009 headwind car SPIRIT crowned itself champion at the Stauning Airport in Denmark. It successfully defended it’s title a year later. Starting the 2011 edition the competition was held on the dike in the Dutch city of Den Helder. With competitors gaining ground SPIRIT eventually finished in third place. The Racing Aeolus 2012 competition was marked by mechanical failures which let to a disappointing fifth place. In 2013 both a regular SPIRIT as well as a SPIRIT 2 participated to test out a newly developed system. The original car finished in eighth place whilst the new model finished fourth. As there weren’t enough participating students SPIRIT eventually had to withdraw from the competition in 2014. In 2015 a fresh team of students developed an entirely new vehicle which ended up finishing in fifth position. Racing Aeolus 2016 saw the further development of the new SPIRIT which let to an overall sixth position. The addition of a new gear system in 2017 had SPIRIT finish fifth.
