ELECTRICAL POWERTRAIN

MONOCOQUE

Construction: CFK - Single chassis in sandwich construction with HV and LV cable ducts in the foam core
Safety:  Safety side, front and rear impact structure with aluminum milled front roll bar, hybrid crash element
Seat & Belt: Two-piece seat in CFK - sandwich construction as part of the firewall, custom 6-point harness
Steering wheel: CFK steering wheel with integrated driver information system

System concept: Modular design, can be supplemented as required, communication via CAN bus

Live telemetry: self-developed, customizable live telemetry

Control unit: control of the drive system, control of the cooling system, vehicle dynamics control (torque vectoring, traction control), recuperation control, control of the Drag Reduction System (DRS)

LV battery: Lithium polymer battery with proprietary battery management

Wiring harness: self-made, four-part wiring harness, reduced power requirements through intensive use of the CAN bus, <400m cable length, <2kg weight

ELECTRONICS

System concept: high downforce at max. Efficiency, easiest disassembly and assembly of each wing, curve-optimized

Front wing: adjustability of the overall wing in height, finest aerodynamic balance adjustment via flaps

Rear wing: adjustability via CFK rods, drag reduction system for minimal air resistance on the straight

Side wing: Optimized flow around the tires, downforce via integrated wings

Thermal Management: Two sidepods with both external and internal airflow
