Orion
The Lausanne Racing Team is a rookie Formula student team in 2019. It gathered 50 people around this project. For its first season Orion went racing in Germany at Hockenheim and in Spain at Barcelona. The design focus was on reliability in order to build a solid basis for the years to come. It is also a more environmental friendly EV thanks to the use of flax fiber for most of the composites.
