Transmission & Friction Losses
Last Updated: February 2, 2026In an Electrathon vehicle, the drivetrain is a series of “Force Transformers”. Any resistance in this system acts as an unwanted force that cancels out the forward movement provided by the motor. 1. The Cost of Friction Efficiency is the key to winning a one-hour rally. Even small mechanical issues create cumulative losses: 2. Alignment...
Battery Management: Discharge & Voltage Curves
Last Updated: February 2, 2026Understanding your voltage levels is essential for maintaining “peak efficiency” throughout a one-hour race. Since you only have a limited energy budget, monitoring your battery’s state of charge ensures you don’t run out of power before the final lap. 1. Voltage Benchmarks For a standard 24V Lead-Acid system (two 12V batteries in series), use these...
Steering Geometry: Ackermann Angle
Last Updated: February 2, 2026Ackermann Steering is a geometric arrangement of linkages designed to ensure that during a turn, the inside and outside wheels follow their own natural paths without “scrubbing.” Why It Matters The Geometry of the Turn When a vehicle turns, the inside wheel must turn at a sharper angle than the outside wheel because it is...
The Physics of Stability
Last Updated: February 2, 2026Vehicle Stability & Weight Distribution To ensure your vehicle remains stable under high lateral loads—especially during tight cornering—adhere to the following center of gravity (CG) and weight distribution standards: 1. Vertical Center of Gravity Maintain a low Center of Gravity. Ideally, the CG should be located below the axles. This minimizes the “lever arm” effect...
Aerodynamic Drag Theory
Last Updated: February 1, 2026In Electrathon racing, wind resistance (drag) is the primary obstacle to maintaining high efficiency. Understanding the relationship between speed and air resistance is vital for any builder. The 15 MPH Threshold Wind resistance becomes a noticeable factor above 15 mph. Unlike mechanical friction, which grows linearly, aerodynamic drag grows exponentially as your speed increases. Design...
Energy Efficiency Calculations
Last Updated: February 1, 2026When comparing the energy density of gasoline to electric propulsion, the numbers for Electrathon vehicles are staggering: Gasoline Energy Baseline: 1 US gallon of gasoline contains approximately 36.6 kWh of energy. Vehicle Power Draw: An Electrathon vehicle drawing 40 amps at 24 volts for one hour uses: Energy Consumption: This equates to 0.960 kWh. Fuel...
