0-60 Calculator
There is no published formula for 0-60 mph, so this simulates the run instead: grip first, power after. The answer is a range, and every assumption behind it is on the page.
The car
Include the driver and the fuel that will be in the car. A published curb weight does not include a driver, so add about 170 lb or 77 kg to it. The default is the 2,454 lb curb weight of a 2024 Mazda MX-5 Miata RF Club plus a driver.
How it puts the power down
The drivetrain sets two things at once: how much power is assumed to reach the road, and how much of the car's weight sits over the driven wheels during the launch. Both are stated assumptions with bands, not measurements of your car.
An engine only makes its rated power at one point on the tachometer. This is the average share of peak power available across the rpm the launch actually uses, and it is a labelled assumption rather than a reading off your dyno sheet.
Hit a target time? (optional)
The same simulation run backwards: the power that lands this car, on these assumptions, on the time you type. The answer is a range across the band, and near the grip floor it is no power at all. The target is yours; the tool has none.

Why there is no 0-60 formula
The quarter mile has several formulas worth quoting. Huntington fitted his in 1958, Hale his in 1986, Fox last revised his in 2001, and a 2008 regression against 243 Road and Track road tests freed the exponents as well as the constants. The quarter mile calculator runs all four and prints their R² values: 0.86 to 0.93 against real trap speeds. Nothing of that quality exists for 0-60 mph, and the reason is visible in those same numbers. The very same regressions fit elapsed time far worse than trap speed, as low as R² 0.62, because elapsed time is dominated by the launch and the launch carries no information about power. A 0-60 run is almost entirely launch. So this page does not pretend to have a fitted constant. It integrates the physics forward in two-millisecond steps, names every assumption it had to make, and prints the range those assumptions produce rather than a single number that would be false precision.
Two phases: grip first, then power
From rest, the limit is not the engine. It is what the tires can put down, which is roughly the coefficient of friction times gravity times the share of the car's weight sitting over the driven wheels. That gives a flat ceiling on acceleration that no amount of extra power can lift, which is why a 700 hp rear-drive car on all-season tires is no quicker to 30 mph than a 400 hp one on the same tires. Above a crossover speed the picture inverts: available power divided by mass and speed falls below the grip ceiling, the engine becomes the limit, and grip stops mattering. That crossover sits at power divided by mass, grip, gravity and axle share, and the tool prints where it lands for your car. Aerodynamic drag and rolling resistance are subtracted the whole way, but to 60 mph they are small: at 60 mph the aero term on a typical car is about a quarter of a metre per second squared against four to six of acceleration. Shift pauses and the first foot of travel that magazines subtract sit on top of all of that, and the tool shows both separately rather than folding them into one figure.
How the model did on five published tests
Every case below was read from the Car and Driver instrumented test that produced it, using the published power rating and the published curb weight plus 170 lb for a driver. The tires were set to summer performance and the shift count to one for every car with a gearbox. Published 0-60 figures carry the one-foot rollout, so they are compared against the with-rollout band.
| Car, as entered | Published | Model band | Central |
|---|---|---|---|
| 2024 Mazda MX-5 Miata RF Club, 181 hp, 2,624 lb, RWD manual | 5.5 s | 4.8 to 6.8 s | 5.7 s |
| 2024 Subaru BRZ tS, 228 hp, 3,030 lb, RWD manual | 5.5 s | 4.5 to 6.5 s | 5.3 s |
| 2015 Volkswagen GTI, 220 hp, 3,295 lb, FWD manual | 6.1 s | 5.2 to 7.1 s | 6.0 s |
| 2024 Tesla Model 3 Performance, 510 hp at the wheels, 4,216 lb, AWD, no shift | 2.8 s | 2.6 to 3.1 s | 2.8 s |
| 2025 BMW X5 M Competition, 617 hp, 5,620 lb, AWD automatic | 3.4 s | 3.2 to 4.0 s | 3.5 s |
All five landed inside the band, and the central estimate was out by 0.18 s at worst, on the BRZ. That is a check on five cars, not a regression on hundreds, and the honest reading of it is narrow. The set spans 181 to 617 hp and 2,454 to 5,450 lb of curb weight, which is a real spread, but it contains no car launched on drag radials, no naturally aspirated engine with a peaky curve, and no turbocharged car with enough lag to matter. The Tesla was entered on the at-the-wheels basis, because a motor rating is not a crank rating with a gearbox behind it, and the tool would otherwise subtract a drivetrain loss that an electric car does not have. Notice also what the Miata and the BRZ show: 26 percent more power and 17 percent more weight, and the same published 5.5 seconds. That is the launch talking, not the engine.
What this tool will not do
It will not tell you your car's time to a tenth, and no calculator can. Two of the five assumptions behind the answer are not physics at all: the drivetrain loss is a workshop convention repeated for decades rather than a measured quantity, and the weight share over the driven axle is a guess about what happens during a launch. Neither of them is a variable the simulation could look up. It also does not know your gearing, so it places shifts at fixed fractions of 60 mph rather than at your rev limiter, and it does not model launch control, torque converter multiplication, tire temperature or a driver's clutch. It will not recommend a tire, a gear or a launch technique. If you want the question asked in the direction that actually works, the horsepower from trap speed calculator reads power from a timing slip, because trap speed washes the launch out and fits real data at R² 0.93. To compare two cars without any of this modelling, the power to weight calculator gives the one ratio that does most of the work, and the top speed calculator handles the other end of the range, where aerodynamics rather than grip sets the limit.
