Quarter Mile Calculator
Calculate your vehicle’s quarter mile time, trap speed, and performance metrics. Understand how weight, power, and aerodynamics affect acceleration.
Step 1: Vehicle Details
Understanding Quarter Mile Performance
The quarter mile is a standard measure of acceleration performance. Your time depends on power-to-weight ratio, traction, and aerodynamic efficiency. Lower times indicate better performance.
Step 2: Additional Options
About Traction Factor
Traction factor accounts for how effectively power is transferred to the ground. Higher values (0.9-1.0) represent optimal conditions like drag slicks on prepped surfaces. Lower values (0.7-0.8) represent street tires on normal pavement.

Power-to-Weight Ratio Analysis
Quarter Mile Calculation Formula
ET = K × (Weight/Power)1/3
The quarter mile time is calculated using a simplified physics-based formula that considers the power-to-weight ratio. Actual performance may vary based on traction, gearing, aerodynamics, and driver skill.
