Lafayette Motorsports started the construction of the current design after successfully competing in 2018. The new design’s mission was to build on the previous design which had placed fourth and compete for silverware at the Formula Hybrid competition. 

Design Breakdown & Overview

The current car design is broken up into subsystems that each are in charge of the development of specific systems within the design.

Top level Electrical System / Interconnect

Interconnect is the connection of all subsystems through proper cabling and connectors on each enclosure with the purpose of providing guidelines of how the car functions on a higher scale. Cabling and other interface systems must be rules compliant and be able to drive in certain conditions using strain relief and waterproofing.

Battery Packs

A battery-based power system that is responsible for providing adequate and accurate current supply to the vehicle. It is regulated by two AMS Boards known as PacMan and CellMan.

EPAL (External Panels & Lights)

The dashboard display provides indicators to the driver regarding the status of the vehicle.

VSCADA (Vehicle Supervisory Control and Data Acquisition)

The VSCADA system stores, displays, and reacts to sensor data.

Cooling System

Provides cooling to the motor/motor controller and keeps it at a safe operating temperature

Motor & Motor Controller

Takes throttle signals and high voltage and inputs control signal to the motor.

Drivetrain System

The drivetrain system provides power to the wheels so the car can move.


The body or frame of the car


Delivers braking pressure to calipers, and accelerometer data to Carman.

Brake System

The brake system that stops the car

Steering System

The steering system that controls the car’s direction


The car’s suspension system
