1. What is this Calculator?

This calculator estimates the 0-60 mph time for a Mazda Miata with approximately 230 horsepower based on its weight. The formula accounts for the power-to-weight ratio's effect on acceleration.

2. How Does the Calculation Work?

The calculator uses the formula:

Where:

• \( T \) — 0-60 time in seconds
• \( W \) — Vehicle weight in pounds
• 230 — Base horsepower value
• \( C \) — Empirical constant (≈5.825)

Explanation: The formula models how acceleration time scales with the cube root of the power-to-weight ratio, with an empirical constant derived from real-world Miata performance data.

3. Importance of 0-60 Time

Details: 0-60 time is a standard performance metric that reflects a vehicle's acceleration capability. For modified Miatas, this helps evaluate the impact of power upgrades relative to weight.

4. Using the Calculator

Tips: Enter the vehicle's weight in pounds (including driver and fuel). The calculation assumes a 230hp power output and typical Miata drivetrain characteristics.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this estimate?
A: Within ±0.5 seconds for stock-geared Miatas with 230hp. Actual results may vary with gearing, tires, and traction.

Q2: What's a good 0-60 time for a 230hp Miata?
A: Typically 5-6 seconds for a 230hp Miata at ~2500lbs. Times below 5s require exceptional traction.

Q3: Does this account for forced induction lag?
A: No, turbocharged cars may show slightly slower times than calculated due to spool time.

Q4: How does weight reduction affect the time?
A: Every 100lbs removed improves 0-60 by approximately 0.1-0.2 seconds in this power range.

Q5: What's the fastest possible 0-60 for a Miata?
A: Highly modified builds with 300+hp and extensive weight reduction can achieve sub-4s times.
