1. What is the Torque-based 0-60 Equation?

The torque-based 0-60 equation estimates a vehicle's acceleration time from 0 to 60 mph based on its weight, torque, gear ratio, and a constant factor. This provides a theoretical estimate of a vehicle's performance.

2. How Does the Calculator Work?

The calculator uses the torque-based equation:

Where:

• \( T \) — 0-60 time in seconds
• \( W \) — Vehicle weight in pounds (lbs)
• \( TQ \) — Engine torque in pound-feet (lb-ft)
• \( GR \) — Gear ratio (dimensionless)
• \( C \) — Constant factor (dimensionless, typically around 1.0)

Explanation: The equation accounts for the relationship between a vehicle's weight, torque output, and gearing to estimate acceleration performance.

3. Importance of 0-60 Calculation

Details: The 0-60 time is a key performance metric for vehicles, helping compare acceleration capabilities and overall performance potential.

4. Using the Calculator

Tips: Enter vehicle weight in lbs, torque in lb-ft, gear ratio, and constant factor. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this calculation?
A: This provides a theoretical estimate. Actual 0-60 times depend on many factors including traction, drivetrain losses, and shift times.

Q2: What's a typical constant (C) value?
A: Most vehicles fall between 0.9-1.1, with 1.0 being a good starting point for estimation.

Q3: Which gear ratio should I use?
A: Use the overall gear ratio in the gear you'll primarily use for 0-60 (often 1st or 2nd gear ratio multiplied by final drive ratio).

Q4: Does this account for turbo lag or traction limits?
A: No, this is a simplified calculation that assumes immediate torque availability and perfect traction.

Q5: How does weight affect 0-60 time?
A: Time increases with the square root of weight, so doubling weight increases 0-60 time by about 41%.
