0-60 MPH Calculator
Estimate your car's 0 to 60 mph acceleration time from horsepower and curb weight.
Uses the power-to-weight formula with real-world correction factors.
0–60 mph acceleration time is the standard automotive performance benchmark measuring how quickly a vehicle reaches 60 miles per hour from a standing start. It combines physics equations of motion with real-world variables like traction, launch control, and drivetrain efficiency.
Physics-based estimation formula: Time = (Velocity × Mass) ÷ (Force − Drag)
Simplified for estimation: 0–60 Time (seconds) ≈ (Weight in lbs × 60 mph) ÷ (Horsepower × 375 × Drivetrain Efficiency)
Or using Newton’s second law: a = F ÷ m → t = v ÷ a
Where:
- F = net tractive force = Engine Torque × Gear Ratio × Final Drive Ratio × Efficiency ÷ Wheel Radius
- m = vehicle mass in kg
- v = 26.82 m/s (60 mph in SI units)
- Drivetrain Efficiency — typically 0.85 for RWD, 0.88 for FWD, 0.83 for AWD
Quarter-mile ET correlation (ET Index): Quarter-Mile ET ≈ 6.269 × (Weight ÷ Horsepower)^0.3333
What each variable means:
- Horsepower vs. torque — torque determines acceleration force; horsepower is torque × RPM / 5,252; high-torque engines (diesels, electric motors) launch harder
- Power-to-weight ratio — the true predictor of acceleration; measured in hp/ton or W/kg
- Traction — ultimate limit below ~300 hp; above that, drivetrain and tires become the constraint
- Launch RPM — manual cars can launch at peak torque RPM; automatic/DSG transmissions optimize this automatically
Reference: 0–60 mph benchmarks:
- Under 3.0s: Supercar / EV performance (Tesla Model S Plaid: 1.99s)
- 3.0–5.0s: Sports car territory
- 5.0–7.0s: Performance sedan / hot hatch
- 7.0–9.0s: Average modern car
- 9.0–12.0s: Economy cars, budget vehicles
- Over 12s: Trucks, heavy SUVs, older economy cars
Worked example: Vehicle: 3,600 lbs, 320 hp, RWD with good tires.
- Power-to-weight = 320 hp ÷ (3,600 ÷ 2,000) = 320 ÷ 1.8 = 177.8 hp/ton
- Simplified estimate: (3,600 × 60) ÷ (320 × 375 × 0.85) = 216,000 ÷ 102,000 ≈ 5.5 seconds
This matches real-world performance of cars like the Ford Mustang GT — validated against published manufacturer specs.
