0-60 Calculator for cars and pickups. It estimates the 0-60 mph time from curb weight, power, drivetrain and tires, or works backward to find the horsepower a target time requires.
Use the curb weight and advertised horsepower from the spec sheet. Samples match a 2024 Mustang GT with the automatic.
Tires, Road and Timing
Grip decides how hard the car can launch. Car and Driver and MotorTrend start the clock after the car rolls one foot, which trims a few tenths from the time.
Speed Splits
| Split | Time |
|---|---|
| 0 to 10 mph | 0.38 s |
| 0 to 20 mph | 1.06 s |
| 0 to 30 mph | 1.74 s |
| 0 to 40 mph | 2.58 s |
| 0 to 50 mph | 3.32 s |
| 0 to 60 mph | 4.24 s |
| 0 to 100 km/h | 4.46 s |
Times from the same simulation. Early splits depend mostly on grip, and later ones mostly on power.
What Upgrades Would Do
| Change | 0-60 | Saves |
|---|---|---|
| +25 hp | 4.17 s | 0.07 s |
| +50 hp | 4.11 s | 0.13 s |
| +100 hp | 4.02 s | 0.22 s |
| −100 lb | 4.2 s | 0.04 s |
| −250 lb | 4.15 s | 0.09 s |
| Track or drag tires | 3.85 s | 0.39 s |
| All-wheel drive | 3.57 s | 0.67 s |
Each row changes one thing and keeps the rest of your setup, so you can see whether power, weight or tires help most.
Same Car, Different Conditions
| Condition | 0-60 |
|---|---|
| Magazine test, dry | 4.24 s |
| Dead stop, dry | 4.55 s |
| Dead stop, wet | 6.58 s |
| All-season tires, dry | 5.05 s |
Why the same car posts different numbers in different tests. Magazine times use a one-foot rollout on dry pavement.
Estimate Acceleration With the 0-60 Calculator
The 0-60 Calculator simulates a full launch, one tiny time step at a time. It tracks tire grip, engine power, air drag and the pause for a gear change. That lets it show when the tires limit the car and when the engine does.
Owners use it to see what a power upgrade, lighter parts or stickier tires would actually change. Shoppers use it to compare cars on equal terms. It works in pounds and horsepower or in kilograms and kilowatts, converting at 2.2046 lb per kg and 0.7457 kW per hp.
How the Launch Is Simulated
Every 2 milliseconds the tool works out the force pushing the car forward. That force is the smaller of what the engine can deliver at the current speed and what the tires can grip. Drag and rolling resistance are then subtracted.
$$a = \frac{\min\left(\dfrac{\eta P_w}{v},\ \mu g\, m f_d\right) – 0.42\,v^2 – 0.012\,m g}{m}$$
In this formula, Pw is power at the wheels in watts and v is speed in m/s. m is the mass with driver and cargo, μ the tire grip and fd the share of weight on the driven wheels. The 0.42 term covers air drag and the 0.012 term covers rolling resistance.
These are model settings, not a published standard. Summer tires grip at 1.1 g, all-season tires at 0.95 and drag radials at 1.3, and wet pavement cuts grip by about a third. Rear-wheel drive puts 62% of the weight on the driven tires, front-wheel drive 55% and all-wheel drive 100%. The engine is assumed to deliver 75% of peak wheel power on average across the gears.
At the defaults, a 3,850-pound Mustang GT with a 150-pound driver and 480 horsepower has about 408 horsepower at the wheels. Its tires grip at 0.68 g. The car is grip-limited up to 42 mph and reaches 60 mph in 4.55 seconds from a dead stop.
Match the “Power Measured At” setting to your number. Entering a 408 wheel-horsepower dyno figure with “Crank” selected takes the drivetrain loss off a second time. The result becomes 4.87 seconds instead of 4.55.
The tool accepts curb weights from 1,000 to 12,000 pounds, 20 to 3,000 horsepower and up to 1,500 pounds of driver and cargo. Target times must fall between 1.5 and 30 seconds.
Why Magazine Times Look Quicker
U.S. magazines start the clock after the car has already rolled one foot, a drag-strip habit called rollout. Racelogic, which makes GPS timing gear, says skipping that first foot can cut up to 0.3 seconds. On the default car, the tool shows 4.24 seconds with rollout and 4.55 from a dead stop.
That gap explains why published times for the same model disagree. Edmunds recorded 4.8 seconds for a 2024 Mustang GT in one comparison test. Launch technique, test surface and rollout all move the number.
Grip Limit or Power Limit
Below the grip-limited speed, the engine is making more force than the tires can use. Extra power does little there, while better tires or all-wheel drive help a lot. The table shows how each single change affects the default car.
| Change From the Default Car | 0-60 With Rollout | Time Saved |
|---|---|---|
| None (480 hp, RWD, summer tires) | 4.24 s | — |
| +50 hp | 4.11 s | 0.13 s |
| +100 hp | 4.02 s | 0.22 s |
| −250 lb | 4.15 s | 0.09 s |
| Track or drag tires | 3.85 s | 0.39 s |
| All-wheel drive | 3.57 s | 0.67 s |
Grip also sets a floor no engine can beat. On summer tires with rear-wheel drive, even unlimited power cannot get this car much below 3.96 seconds. With all-wheel drive, the floor drops to about 2.44 seconds.
The transmission matters too, because each shift is a short gap in power. The tool allows 0.15 seconds for a modern automatic, 0.10 for a dual-clutch and 0.35 for a manual. On the default car, that turns 4.24 seconds into 4.19 with a dual-clutch and 4.44 with a manual.
Quarter Mile From Hale’s Formula
The first card estimates the quarter mile with Patrick Hale’s drag-racing formulas, as documented by stealth316. Both use crank horsepower and race weight in pounds.
$$ET = 5.825 \left(\frac{W}{hp}\right)^{1/3} \qquad MPH = 234 \left(\frac{hp}{W}\right)^{1/3}$$
At 4,000 pounds with the driver and 480 horsepower, that gives an 11.8-second pass at 115.4 mph. Hale’s constants assume a good launch on a prepared track. Older fits by Huntington and Fox predict slower times, and the Horsepower Quarter Mile Calculator covers the full quarter-mile picture.
Working Out the Power a Target Time Needs
Switching “What to Find” to “Power Needed for a Target” runs the simulation again and again until it lands on your time. The default Mustang needs about 349 horsepower for 5.0 seconds and about 600 for 4.0 seconds, both timed with rollout.
If the target is below what the tires allow, the tool says so instead of giving a huge horsepower figure. A 3.5-second run is out of reach for this car on summer tires, whatever the power. The Power To Weight Ratio Calculator shows how the pounds-per-horsepower figure compares with other cars.
Entries That Skew a 0-60 Calculator Result
Taking weight from the door sticker is a common slip. That label shows the gross vehicle weight rating, the most the car may weigh fully loaded, not its curb weight. Use the curb weight from the spec sheet and add the driver in the payload field.
Leaving summer tires selected on a car that wears all-seasons flatters the result. The default car goes from 4.55 to 5.05 seconds from a dead stop on all-season tires. Tire choice matters more than most bolt-on power upgrades.
Comparing a GPS meter reading with a magazine number without matching the timing method is the third. Pick “From a Dead Stop” if your meter’s rollout option is off, and “Magazine Test” if it is on.
What Changes a Car’s 0-60 Time
Why is my GPS meter slower than the magazine time?
Most of the gap is usually rollout. Magazines skip the first foot of movement, which Racelogic puts at up to 0.3 seconds. Turn on your meter’s one-foot rollout option before comparing.
The rest comes from conditions and launch. Street pavement grips less than a prepared test surface. Heat and altitude also cut engine power, which the Hp Loss At Altitude Calculator estimates.
Does cutting weight help as much as adding power?
Pound for pound, weight cuts help less than their share of the total suggests on a grip-limited car. On the default Mustang, removing 250 pounds saves 0.09 seconds, while adding 50 horsepower saves 0.13. Both matter more once the car is past its grip-limited speed.
A lighter car also stops, turns and uses fuel better, so the benefit goes beyond straight-line speed. The Wheel Horsepower Calculator shows how much of an upgrade actually reaches the pavement.
Why are electric cars so quick to 60?
An electric motor makes full torque from a standstill, has no gear changes and loses less power in the drivetrain. The tool models EVs with a 10% drivetrain loss and 95% of power used, against 75% for gas engines.
Set to 480 horsepower with all-wheel drive and a single-speed transmission, the default weight reaches 60 in about 2.68 seconds with rollout. That is 1.56 seconds quicker than the gas car. Once past 60, top speed depends on power and drag, which the Top Speed Calculator works out.
