UCalgary Racing continued making strides in their development of competitive electric vehicles with the UCR-02 during the 2024-2025 season. The UCR-02 was an iteration of its predecessor, focused on improved driving characteristics, electrical system integration, efficiency, and manufacturing practices. A redesigned battery pack increased the maximum capacity and voltage while decreasing weight. Serviceability was also drastically improved with the new pack design. Data was collected through two CAN channels and recorded to a Kvaser Memorator Pro data logger, allowing us to make data driven improvements and improve our simulations.

The UCR-02 featured a new architecture for the Tractive System Junction Box (TSJB), allowing all its components to be centralized above the UniTek Bamocar D3 motor controller. This controller sent power to the Emrax 228 motor, which transmitted its kinetic energy to the wheels through a torque-optimized gear ratio and a Drexler limited-slip differential.

A remodeled 4130 chromoly spaceframe allowed for the integration of the front suspension within the nosecone which improved both the aerodynamics of the vehicle and the visibility for the driver. The UCR-02’s suspension package built off the 01’s success with a 50% decrease in the drivers steering forces while maintaining the optimized tire performance window. A custom pedal box was developed through intensive kinematic analysis, allowing the driver to customize the throttle resistance to their preference. Additionally, its mounting system redesign greatly eased adjusting the pedal box placement.
