This 0-60 mph calculator estimates how quickly a car accelerates from a standstill to 60 mph using its horsepower and weight. It's a quick way to predict acceleration for a build or mod, compare two cars, or sanity-check a manufacturer's published 0-60 time — though real launches depend heavily on traction and drivetrain.
0-60 MPH Formula
0-60 mph (or 0-100 km/h) is the most widely quoted acceleration benchmark for road cars. It's driven by power-to-weight ratio: more horsepower per pound means quicker acceleration. But unlike a steady-state top-speed number, 0-60 is dominated by what happens in the first second — how well the tires hook up and how fast the driver or launch control can put power down without wheelspin.
Why Traction and Drivetrain Decide the Real Number
This is an estimate based purely on power and weight, so it can't see the single biggest variable: grip. All-wheel-drive cars launch hard because all four tires share the load, often beating the math by half a second or more. Front-wheel-drive cars suffer wheelspin and weight transfer off the nose, so they typically run slower than predicted. Rear-wheel-drive sits in between and is highly sensitive to tire compound and launch technique. Turbo lag, gearing, and whether 60 mph falls in first or second gear all shift the result too.
0-60 and Power-to-Weight Ratio
A useful rule of thumb for grippy cars: 0-60 time in seconds ≈ 0.7 ÷ (power-to-weight in hp/lb). So 0.100 hp/lb gives roughly 7 seconds, and 0.150 hp/lb about 4.7 seconds. The relationship breaks down at the extremes, where tire grip — not power — becomes the limiting factor. Use our power-to-weight ratio calculator to see where your car lands.
0-60 Times by Power-to-Weight
| Power-to-Weight | Est. 0-60 (ideal) | Category |
|---|---|---|
| 0.050 hp/lb | ~9–11 s | Economy car |
| 0.075 hp/lb | ~6.5–7.5 s | Hot hatch |
| 0.100 hp/lb | ~5–6 s | Sports sedan |
| 0.150 hp/lb | ~3.5–4.5 s | Performance / muscle |
| 0.200+ hp/lb | ~2.5–3.5 s | Supercar (with grip) |

Frequently Asked Questions
Traction is the main limiting factor. If your tires spin, your 0-60 time will increase dramatically.
Electric vehicles deliver maximum torque instantly at 0 RPM, unlike gas engines which must rev up. They also have highly advanced traction control.
They're rough guides. Real 0-60 times depend heavily on traction, gearing, transmission type, and launch technique, which a power-and-weight formula can't fully capture.
Weight, drivetrain layout, tire grip, and gearing all differ. An AWD car often launches harder than a RWD car of equal power because it puts more power down without wheelspin.
It's the best single predictor, but traction sets the ceiling. Below a certain weight or above a certain power level, grip — not power — limits acceleration.
