About this calculator
This rough estimate uses a historical horsepower-to-weight relationship. Actual results depend on gearing, launch, tires, surface, weather and how power is measured. Enable comparison to enter a second car. A positive time difference means the comparison car is estimated to be slower.
Worked example
calculated with the default values below
Engine horsepower 300 hp · Curb weight 3,400 lb · Compare another car Off · Comparison car horsepower 250 · Comparison car weight 3,600 Estimated 0–60 mph 4.85 s · Power to weight 0.0882 hp/lb · Estimated quarter-mile time 13.08 s · Estimated quarter-mile trap speed 104.2 mph
General background references
Disclaimer
These calculators give estimates for general information only. Real fuel consumption, performance and range vary with driving style, load, terrain, temperature and vehicle condition. Do not rely on these results for towing limits, payload or braking decisions — use the rating plate of your vehicle.
Implementation source
This record describes the implementation used by this page. It is not independent validation. External references, when available, support only the stated formula or definition; estimates and custom rules retain their own assumptions.
Formula and variables
t = (0.3542 ÷ (P ÷ W))^(1 ÷ 0.88)
- t
- Estimated 0–60 mph time (s)
- P
- engine horsepower (hp)
- W
- vehicle weight (lb)
The fit is based on historical light-duty-vehicle data from 1978–2014. Quarter-mile elapsed time and trap speed use separate empirical estimates; all results are approximate.
Frequently asked questions
How should I interpret the 0–60 estimate?
It applies a historical horsepower-to-weight fit, then estimates quarter-mile time and trap speed from separate empirical formulas. It is a comparison aid, not a prediction of a specific car’s tested result: gearing, launch control, tires, surface, weather, vehicle condition and measurement method all matter.
