ER18

Based on evaluations and priorities, the management took the decision to switch back to the CBR600RR engine as powerplant for ER18 to improve the power to weight ratio. The main technical goals for ER18 were increased reliability and power to weight ratio. This car should become the first in LiU Formula Student’s history to pass endurance with the Honda engine, which it did. Twice.

With features such as equal length headers, a custom made engine map and a 3D-printed air intake, the engine was optimized for power. The car also featured electric throttle control, launch control, redesigned front suspension and a redesigned aero package for improved dynamic performance. The car competed in both FSUK and FSG finishing 21th and 46th respectively.
