About the 0-60 Time Calculator
This 0-60 calculator estimates how quickly a car accelerates from a standstill to 60 mph, plus its 0-30 mph and 0-100 km/h (62 mph) times. Enter peak horsepower, the weight of the car with driver, which wheels are driven, the transmission or powertrain and the type of tyres, and it simulates the run step by step.
It is useful for comparing cars before you buy, judging what a power upgrade or weight reduction will do, or checking whether a claimed time is plausible. At low speed acceleration is limited by tyre grip, which is why all-wheel-drive cars launch harder; above that, it is limited by power, so the power-to-weight ratio dominates.
The model’s power and grip factors were tuned so typical sedans, V8 coupes and dual-motor EVs land near their published road-test times, but it is an estimate, not a measurement: gearing, torque curve and launch technique all matter. Launch control, dual-clutch gearboxes, very sticky tyres and the 1-foot rollout that magazines subtract can make real times quicker, while altitude, heat and traction aids cutting power can make them slower.
With the default inputs, the 0-60 mph time is 5.9 s. Change any value above to recalculate instantly.
How to use the 0-60 time calculator
- 1Enter the car’s peak horsepower from the spec sheet.
- 2Enter the curb weight plus the driver (about 150–200 lb).
- 3Choose the drivetrain and powertrain type.
- 4Pick the tyre and road condition.
- 5Read the 0-60 time and see how changes in power or weight affect it.
Formula and method
The calculator steps through the run in 0.01-second increments (0.1 s after the first 15 seconds for slow vehicles). At each step the driving force is the smaller of two limits: the traction limit (tyre grip μ × weight × the share of weight on the driven wheels d — 55% for FWD, 70% for RWD once weight transfers rearward, 100% for AWD) and the power limit (usable wheel power ÷ current speed). Aerodynamic drag (ρ = 1.2 kg/m³, CdA = 0.7 m²) and rolling resistance (Crr = 0.012) are subtracted, and the net force divided by mass gives acceleration.
Usable wheel power η × P accounts for drivetrain losses and the fact that an engine is not at peak power throughout the run (gear changes, rev range): about 63% of peak for automatics, 61% for manuals and 72% for EVs, calibrated to typical published 0-60 results. Times are from a true standstill without magazine-style rollout.

Worked examples
300 hp front-drive sedan, 3,600 lb
At 12 lb per horsepower, a 300 hp FWD sedan is grip-limited below about 36 mph and then power-limited. The simulation reaches 30 mph in about 2.5 s and 60 mph in about 5.9 s — in line with V6 family sedans.
460 hp rear-drive muscle car with a manual
With 8.4 lb/hp and rear-wheel drive the car is traction-limited early, then pulls hard. The estimate of about 4.4 s matches typical road tests of V8 pony cars.
Dual-motor EV, 346 hp and 4,000 lb
All-wheel drive puts all the weight on driven tyres, and an EV delivers a larger share of its peak power across the run, so it reaches 60 mph in about 4.2 s and 100 km/h in about 4.5 s.
Frequently asked questions
How do you calculate 0-60 time from horsepower?+
A 0-60 estimate needs both horsepower and weight. This calculator simulates the run: grip limits acceleration at low speed and power ÷ speed limits it after that, with drag and rolling resistance subtracted. The power-to-weight ratio is the single biggest factor.
What is a good 0-60 time?+
Most modern family cars run 0-60 mph in about 6–9 seconds. Under 6 seconds feels quick, under 4 seconds is sports-car territory, and the fastest EVs and supercars break 3 seconds.
Why are electric cars so quick 0-60?+
Electric motors deliver strong torque from zero rpm, there are no gear changes, and power is controlled precisely to the limit of traction. Many EVs also have all-wheel drive, which puts all of the car’s weight on driven tyres and nearly doubles the usable grip at launch.
How much does weight affect 0-60?+
Once a car is power-limited, its time scales roughly with weight per horsepower. Removing 100 lb from a 3,500 lb car (about 3%) typically saves around 0.1–0.2 s, similar to adding 3% more power.
Why do magazine 0-60 times look faster?+
US magazines commonly subtract a 1-foot rollout, which removes the slowest first moment of the run and can trim around 0.2–0.3 s. They also use launch control and ideal conditions. This calculator estimates from a true standstill.
