  • Batteries: Upgraded 12V and 48V batteries with an integrated Battery Management System and the provision of LIMP modes.
  • 48V Power Delivery Unit: Intended to remove cranking issues and improve stability.
  • Emergency Braking: Full hydraulic active braking system based on speed to reduce the incidence of flat spot tires and decrease stopping distance in Emergency braking conditions.
  • Secondary IMU: Used on an alternative CAN bus for redundancy.

  • Torque Limiter: The steering actuator now has a torque limiter, preserving the power steering actuator (PSA) in the event of a crash.
  • Top Ring: The Top Ring has been fitted with a damper to isolate components from vibrations.
  • Skid Layout: Implementation of quick-release connectors and a substantial weight reduction of around 50kg.
  • HLPC RAM: Tested different RAM and connectors.
  • GNSS & 5G: New antennas with serviceable connectors that should reduce noise and improve ease of maintenance/replacement.
  • Camera: New, faster connection to the camera with a new lens.
  • Hard Disk: New PCIe hard drive with improved vibration resistance.
  • Looms: All wiring looms have been upgraded to motorsport standards, including connectors.

  • Alternator: The alternator has been upgraded to a new Honda OEM unit that is smaller with less inertia while also offering more stable voltage output.
  • Fuel Pipe: To address fuel leakage and fire issues, a new fuel line has been validated and put into use.
  • Gearbox: Shorter gear ratios will enable teams to extract greater performance from the engine on the tracks used by A2RL.
  • Gearbox Calibration: Reduced the harshness of upshifts and downshifts while making power delivery more progressive.
