What formula does this calculator use?

The calculator estimates 0–60 mph as 0.70 × (Weight / (HP × Drivetrain_Efficiency))^0.80, then applies a simple launch floor of 2.8 seconds for FWD, 2.5 seconds for RWD, or 2.3 seconds for AWD. The 0–100 km/h estimate is 1.06 times the 0–60 estimate. These are broad empirical heuristics, not a vehicle dynamics simulation.

How accurate is this estimate?

Treat the result as a directional power-to-weight estimate rather than a measured prediction. Traction, launch technique, gearing, torque delivery, aerodynamics, altitude, temperature, tires, and hybrid or EV boost can move an actual time substantially.

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. The separate launch floor is only a coarse allowance for that traction difference.

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.

Does engine torque affect 0 to 60 acceleration?

Yes. While peak horsepower defines overall power-to-weight potential, low-end torque and power curve shape heavily influence off-the-line launch acceleration and real-world times.

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.

Estimate: T₆₀ = 0.70 × (Weight ÷ (HP × Eff))^0.80, subject to a simple drivetrain launch floor. This is a comparison heuristic, not a full traction and gearing simulation.
