1. What is the Time-Torque-Weight Relationship?

The relationship between time, torque, and weight is fundamental in vehicle performance calculations. Higher torque generally results in better acceleration and lower mile times, while increased weight has the opposite effect.

2. How Does the Calculator Work?

The calculator uses the simplified equation:

Where:

• \( Time \) — Estimated mile time (minutes)
• \( Torque \) — Engine torque in Newton-meters (Nm)
• \( Weight \) — Vehicle weight in kilograms (kg)
• \( k \) — Empirical constant (0.2 for typical vehicles)

Explanation: The equation shows that mile time is directly proportional to weight and inversely proportional to torque.

3. Importance of Torque in Performance

Details: Torque is crucial for acceleration and pulling power. Higher torque values typically correlate with better performance, especially for overtaking and hill climbing.

4. Using the Calculator

Tips: Enter torque in Nm and weight in kg. Both values must be positive numbers. The calculator provides an estimate based on typical vehicle characteristics.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this calculation?
A: This provides a rough estimate. Actual performance depends on many factors including gearing, aerodynamics, and traction.

Q2: Should I use peak torque or torque at specific RPM?
A: For most estimates, peak torque is sufficient, but detailed analysis would consider the torque curve.

Q3: Does this account for transmission losses?
A: No, the calculation assumes perfect transmission efficiency. Real-world times will be slightly longer.

Q4: What's a good torque-to-weight ratio?
A: Generally, ratios below 10 kg/Nm are considered good for performance vehicles.

Q5: Can I use this for electric vehicles?
A: Yes, but EV torque characteristics are different - they often have maximum torque at zero RPM.
