How the estimate works
Quarter-mile ET and trap speed use the well-known Huntington drag-racing relationships, which correlate elapsed time and trap speed with power-to-weight:
ET = 5.825 × (lb ÷ hp)⅓ · trap = 234 × (hp ÷ lb)⅓
0–60 is estimated from power-to-weight and adjusted for drivetrain (AWD launches best, FWD spins sooner). Treat all figures as a ballpark — a great launch, sticky tyres or short gearing can beat them; a bad launch won't.
FAQ
Crank or wheel power?
Use crank (flywheel) power to match the formulas and manufacturer figures. Wheel hp will read a bit slower.
Why include driver weight?
Acceleration is about total moving mass. Add ~75–90 kg for a driver (and fuel) for a realistic figure.
