How it works

On WFR26-E nearly every electronic part is student designed and built, including the TSAL, the low voltage motherboard, two vehicle control units and the power distribution module.

The accelerator uses two redundant position sensors; any disagreement, lost signal or fault commands zero torque.

Electronic fuses log fault events, and the brake system plausibility device was rebuilt from scratch with analog parts only. The rear harness was split into dedicated harnesses and bench tested before going in the car.

Build the next one.

Recruitment is open. You do not need to be an engineer or know anything about racing. Bring your curiosity and we will teach you the rest.
