Gear Ratio

Gear ratio refers to the relationship between the rotational speeds of two interlocking gears. In FSAE cars, achieving a top speed of 120 kph before the motor enters field weakening at 6500 RPM requires selecting gear ratios that balance torque and speed to optimize acceleration and performance.

Battery Calculations

Sizing the battery for an FSAE EV is crucial for balancing performance, weight, energy density, safety, and cost. It directly impacts performance, weight distribution, and overall agility on the track, while also affecting safety and budget considerations.
