What measured acceleration time tells you
Average acceleration is the change in speed divided by elapsed time. A 0–100 km/h run uses a 100 km/h speed change converted to m/s. Other intervals, such as 60–100 km/h, work the same way. For a 0–60 mph run, enter 96.56064 km/h as the final speed.
a = (final km/h − initial km/h) ÷ 3.6 ÷ seconds
Example: 0–100 km/h in 10 seconds
The speed change is 27.78 m/s. Dividing by ten seconds gives 2.78 m/s² average acceleration, or approximately 0.283 g. If acceleration were constant, average speed would be 50 km/h and the vehicle would cover about 138.89 m.
Why this is not a horsepower-based prediction
This tool analyzes an entered time rather than predicting it from vehicle weight and horsepower. Real acceleration changes during shifts and depends on traction, resistance and the engine curve. Exact distance needs a speed-time record; quarter-mile ET or horsepower from a drag run requires a different model.
