Seat & restraining system: two-part seat made of CFRP-sandwich-structure with optimised driving ergonomics, 6-point performance belt
Steering wheel: CFRP with ergonomical 3D-printed handles, customized to each driver

ELECTRONICS

System concept: modular structure, expandable, communication via CAN-bus
Live-telemetry: self-developed, customizable 
Control unit: control of the drivetrain, regulation of the cooling system, regulation of driving dynamics (torque vectoring, traction control), regulation of recuperation, control of the drag reduction system (DRS)
Battery: lithium-polymer-battery with self-developed battery management
Cable Harness: self-made, 4-part harness, reduced power demand through intensive use of the CAN-bus, < 400 m cable length, < 2 kg weight
