What formula does this calculator use?

The calculator uses a power-to-weight ratio formula: Time = (Weight / (HP × Drivetrain_Efficiency)) ^ 0.333 × Constant. The constant is calibrated to match real-world 0-60 measurements for a wide range of production vehicles. Drivetrain efficiency accounts for parasitic losses in the transmission and driveline.

How accurate is this estimate?

Results typically fall within 10–15% of measured times for street cars under normal conditions. Variables such as traction, launch technique, altitude, temperature, tire type, and gear ratios are not modeled. Use results as a directional guide, not a guarantee.

What drivetrain efficiency values are used?

Front-wheel drive (FWD) uses 0.90 (90%), rear-wheel drive (RWD) uses 0.88 (88%), and all-wheel drive (AWD) uses 0.85 (85%). AWD systems have more rotating mass and driveline components, reducing efficiency, though they often launch better in practice. This calculator models mechanical efficiency, not traction advantage.

Should I use horsepower at the wheels or at the crank?

Use the advertised (crank) horsepower figure, which is what manufacturers publish. The drivetrain efficiency factor already accounts for the power lost between the engine and the wheels.

What weight should I enter?

Enter the vehicle's curb weight plus the driver's weight (approximately 180 lb / 82 kg). For the most accurate result, use the actual total weight of the vehicle as it will be driven during the run.

Why does AWD show a slower time than RWD with the same power?

The calculator models drivetrain efficiency only. In practice, AWD cars often achieve faster 0-60 times by eliminating wheel spin on launch. If you want to model a perfect AWD launch, try increasing the effective HP by 5–8% to simulate the traction advantage.

Drivetrain Efficiency Reference

RWD — 88% efficiency

Classic layout. Good mechanical efficiency; traction-limited on launch.

FWD — 90% efficiency

Fewer driveline components. Best mechanical efficiency of the three.

AWD — 85% efficiency

Most driveline losses, but superior traction compensates in practice.

Formula: T = (Weight ÷ (HP × Eff)) ^ 0.333 × K where K is a calibration constant (6.29 for mph, 6.70 for km/h).
