# 0-60 MPH Calculator

Estimate 0-60 mph and quarter mile times from horsepower, weight, and drivetrain. See power-to-weight ratio and wheel horsepower after drivetrain losses.

## What this calculates

Curious how fast your car could hit 60? Enter your horsepower, curb weight, and drivetrain type to get an estimated 0-60 mph time, quarter mile, and power-to-weight ratio. Useful for comparing stock specs, planning modifications, or just settling arguments.

## Inputs

- **Horsepower (at crank)** (hp) — min 10, max 5000 — Brake horsepower as rated by manufacturer
- **Curb Weight** — min 500, max 20000
- **Weight Unit** — options: Pounds (lbs), Kilograms (kg)
- **Drivetrain** — options: FWD (Front-Wheel Drive), RWD (Rear-Wheel Drive), AWD (All-Wheel Drive) — AWD launches harder due to better traction
- **Transmission** — options: Manual, Automatic / DCT — Automatic/DCT shifts faster for better 0-60 times

## Outputs

- **Estimated 0-60 mph** — formatted as text — Estimated 0-60 mph time
- **Estimated 0-100 km/h** — formatted as text
- **Power-to-Weight Ratio** — formatted as text
- **Est. Wheel Horsepower** — After drivetrain losses
- **Est. Quarter Mile** — formatted as text — Rough estimate based on weight and power

## Details

This calculator uses an empirically-tuned power-to-weight formula along with the Hale formula for quarter mile estimates. Real-world times vary based on traction, elevation, temperature, tire compound, and driver skill.

What affects 0-60 time:

  - Power-to-weight ratio -- the single biggest factor. Less weight and more power = faster.

  - Drivetrain -- AWD launches harder because all four tires grip. FWD can spin and bog at high power levels.

  - Transmission -- modern automatics and dual-clutch gearboxes shift faster than most humans can with a manual.

  - Tires -- sticky summer tires can knock 0.3-0.5 seconds off vs all-seasons.

  - Traction -- cold tires, wet pavement, or gravel will add time regardless of power.

Drivetrain losses:

  - FWD: ~15% loss from crank to wheels

  - RWD: ~15% loss from crank to wheels

  - AWD: ~20% loss (more drivetrain components), but better traction at launch

## Frequently Asked Questions

**Q: How accurate is this estimate?**

A: For typical street cars, this calculator is usually within 0.5-1.0 seconds of real-world results. Extreme cases (very high-power, turbo lag, launch control, drag slicks) can differ more. Real magazine test numbers always trump calculated estimates because they account for traction, launch technique, and conditions.

**Q: Why is AWD faster to 60 even with more drivetrain loss?**

A: AWD loses more power through the drivetrain, but all four tires share the load at launch. This means the car can put down more power without spinning the tires. On paper, a RWD car with the same power is faster, but in practice the AWD car often wins the 0-60 sprint because it can use more of its power off the line.

**Q: What is a good power-to-weight ratio?**

A: Under 10 lbs/hp is sports car territory (5-6 second 0-60). Under 7 lbs/hp is genuinely fast (under 4 seconds). Under 5 lbs/hp is supercar level. Most economy cars sit around 15-20 lbs/hp.

**Q: Does the quarter mile estimate account for aerodynamics?**

A: No. The Hale formula is a weight-and-power estimate that works well for most street cars but does not factor in aerodynamic drag, gearing, or turbo lag. At very high speeds (above 130 mph), aero drag becomes a significant factor.
