ER17

For 2017, the team focused on going from the four cylinder Honda CBR 600 to the much smaller and more compact KTM 450 engine. A lot of work therefor had to be done toward redesigning the powertrain, leading to the design choice of keeping the suspension and frame geometry of ER16. Instead work was shifted towards optimizing manufacturing, with the introduction of lasercut steel for the frame and watercutting for low manufactoring cost as well as a new body and overall look. In the end, the car weighed 23 kilos less than its predecessor and competed in Formula Student UK 2017 where it finished all events for the first time in LiU FS history and finished 18th place.
