Method version: 29 August 2026 · Coverage is expanded and corrected as stronger evidence becomes available.
What one record represents
A Time to 100 record describes a specific vehicle variant rather than a model name in general. Its useful identity fields include model year, make, model, engine or motor configuration, transmission, drivetrain, body style, market status and region. Two cars that share a badge can have different acceleration because their powertrain, mass, tyres or calibration changed.
Evidence order
- Official manufacturer material. Used for a claimed result when the page or document identifies the relevant vehicle.
- Instrumented independent testing. Used when the publication, vehicle and timing basis are identifiable.
- Engine- and generation-level specification data. Used to support catalogue coverage and explicitly labelled estimation where an exact measured result is unavailable.
A manufacturer claim and an independent road test are not merged into a fictional average. The evidence label remains attached to the number so readers can make the comparison appropriate to their purpose.
Standards we do not silently mix
0–100 vs 0–60
One hundred kilometres per hour is 62.14 mph. A 0–60 mph test ends at 96.56 km/h and is not relabelled as 0–100 km/h.
Rollout
A result timed after initial movement is kept separate from a true standing-start result whenever the source discloses the timing method.
Claim vs test
An official claim and an independently instrumented result answer different evidence questions. Both can be useful when clearly labelled.
Exact vs estimated
A missing performance field may be estimated from the closest defensible engine or comparable vehicle, but the interface marks it as estimated.
Quality checks and corrections
New records are checked for plausible units, exact variant identity, source accessibility and internal consistency. Outliers receive extra review. Model availability and manufacturer pages can change; an old result is not automatically applied to a new model year. The index is versioned with the website so corrections can be traced in the publication history.
How to cite Time to 100
If you use a comparison in an article, research note or video, link to the relevant page and name the exact vehicle, figure, evidence basis and access date. A suggested web citation is:
Time to 100, “Global Vehicle 0–100 km/h Acceleration Index,” timeto100.com, accessed [day month year].
Underlying engine and generation data includes the vehicle-makes-models dataset under its stated ODbL terms. Manufacturer names and specifications remain the property of their respective owners. Citation does not imply manufacturer endorsement.
