Cross-check: the classic Hale formula says 13.0 s @ 105 mph for this power and weight. It ignores traction and gearing, so it tends to flatter heavy, high-power and FWD cars.
KNOW THE TERMS
- Rollout
- Magazines and drag strips start the clock after the car has moved about 1 ft. These estimates do the same, which takes roughly 0.2–0.3 s off a true standing start.
- Trap speed
- Speed at the end of the quarter mile. It tracks power-to-weight closely and barely depends on the launch, so it's a good check on real power.
- Traction-limited
- The tires can't put down all the power, so more grip helps and more power doesn't. Most cars are traction-limited for the first part of the run.
- Hale formula
- A classic quarter-mile estimate from power and weight alone. Quick and well known, but it can't see traction, gearbox or tires.
ASSUMPTIONS
- A good launch on a prepared, dry surface at sea level, around 20 °C. Heat, altitude and a dusty road all slow things down.
- Peak power is the spec-sheet figure unless you choose wheel power. Driveline loss is assumed by layout (12–20%).
- Gearing is a typical close-ratio road car. Very long or very short gearing will move the numbers.
- The model was fitted to published road tests of eleven very different cars; across those its average error was about 0.3 s to 60 and 0.1 s in the quarter. The likely range is shown wider than that on purpose.
- Not for street racing. Drag strips and track days are the place for this.
