0-60 mph Time Calculator

It uses an empirical power-law regression on the power-to-weight ratio: time equals 0.706 times (weight in pounds divided by horsepower) raised to the 0.823 power, then multiplied by a drivetrain factor. The constants were fit to a panel of real production cars from economy sedans to supercars, with rear-wheel drive as the baseline.

You need curb weight in pounds and rated crank horsepower, plus a drivetrain choice. Use the ready-to-drive curb weight (not dry weight or payload) and the manufacturer's power figure. Picking the right drivetrain (FWD, RWD, AWD, or electric AWD) sharpens the estimate by accounting for how the car puts power down off the line.

Two cars with the same power-to-weight can post different 0-60 times because of launch traction. Front-wheel drive tends to spin or lose grip at launch and reads slightly slower (factor 1.04), all-wheel drive hooks up harder (0.95), and an electric AWD car adds instant torque from a standstill (0.86). Rear-wheel drive is the regression baseline at 1.00.

Across the sample of production cars used to fit the model, predictions land within about a quarter second of the published 0-60 time on average. Individual cars still vary by several tenths because gearing, tire compound, surface, launch technique, temperature, and altitude all matter and are not in the formula. Treat the number as a ballpark, not a tested track result.

Enter crank horsepower, the rated figure manufacturers publish, because that is what the regression was fit against. Wheel horsepower measured on a dyno is lower than crank power due to drivetrain losses (roughly 10 to 15 percent), so using a wheel figure would make the estimated 0-60 time slower than reality.

Yes. Choose the custom drivetrain option and enter your own factor between 0.5 and 2.0. The factor multiplies the rear-wheel-drive baseline estimate, so a value below 1.0 makes the car quicker (better launch) and above 1.0 makes it slower. This is handy for sticky drag tires, poor surfaces, or unusual setups.
