About us

0-60calc.com is an independent automotive calculator site. It exists to answer one question well: how quick is a car, a motorcycle or an EV, and what would change that. Every tool on the site runs in your browser, is free to use and needs no account.

What we make

Our calculators estimate 0-60 mph and 0-100 km/h times, quarter-mile and 1/8-mile ET and trap speed, horsepower from torque or from a time slip, and drivetrain loss, with more tools on the way. They share one consistent model, so a car that estimates at 5.2 seconds to 60 on the homepage runs the same 13.17-second quarter mile on the quarter-mile page.

Who writes 0-60calc

Every calculator and guide on this site is built and written by the 0-60calc Team. We compare our estimates with published instrumented road tests from outlets such as Car and Driver, MotorTrend and Edmunds, and we show where they differ instead of hiding the misses. Each guide shows the month it was last updated, and we revise guides when newer tests change the numbers.

Found something wrong? Tell us and we will check it against the source and correct it.

How the estimates work

Acceleration is driven mostly by power-to-weight ratio. We start from that and apply small, published adjustments for drivetrain, gearbox and vehicle type. Quarter-mile figures use the Hale formulas that drag racers have relied on since the 1980s. Every page shows its formula and constants in full, so you can check the maths or reproduce it yourself.

These are estimates. Real runs depend on traction, tires, weather, altitude, gearing and the driver, and no formula captures all of that. We say so on every result slip, and we mean it: use our numbers as a target range, not a promise.

Accuracy and corrections

We test the model against published road-test figures and refine it when we find a consistent gap. If you spot a mistake, a broken calculation or a figure that doesn't match your own results, tell us. Corrections are made as soon as we can verify them.

How we check our numbers

We compare the calculators with instrumented road tests published by Car and Driver, MotorTrend, Road & Track, Edmunds and MotorWeek, and we publish those comparisons, including where our estimates miss. See our 0-60 estimates vs real road tests and our quarter-mile estimates vs real time slips.

How we build and update a calculator

Every calculator starts from a published formula or an exact unit definition. Unit converters such as mph to km/h, hp to kW and Nm to lb-ft use the conversion factors in NIST Special Publication 811, so nothing in them is estimated. Performance calculators, such as 0-60, quarter-mile and horsepower from a time slip, use power-to-weight models, and every one prints its formula and constants so you can check the maths.

Each calculator page shows the month it was last updated and ends with a Sources and method box that says what it is based on. When we change a formula, a factor or a table, we update that date, re-run the worked examples on the page and compare the results with the road tests we have on file. If a published test disagrees with our estimate, we show both numbers instead of quietly adjusting ours.

Tested times vs manufacturer claims

Whenever we quote a car’s 0-60 or quarter-mile time, we say whether it comes from an independent test or from the manufacturer, and who measured it. Testers differ in method: Car and Driver and Road & Track subtract a one-foot rollout, Edmunds does not, and manufacturers often use a prepared drag strip. We keep those numbers apart so you are never comparing a claim with a test.

Sources we rely on

• Engine ratings: manufacturer figures, which in the US are rated under the SAE J1349 net power standard.
• Road tests: Car and Driver, MotorTrend, Road & Track, Edmunds and MotorWeek, linked on every page that uses them.
• Dyno results: published articles and tuner test reports, labelled with who ran them and on what dyno.
