Limitations and reproducibility
- Only acceleration, stock configuration and the documented simulation conditions are covered. No price, reliability, fuel-cost or handling verdict is inferred.
- Race results are model estimates even when calibration anchors come from instrumented tests. Source fields and estimated inputs are listed per vehicle.
- Null speed gates mean not reached during this 1 km run. Rolling intervals are differences within this standing-start run.
- The configured stock top-speed ceiling and the maximum speed achieved within 1 km are different values.
- A replay uses these frozen stock inputs with the currently deployed engine. The versioned citation result remains fixed if the engine later changes.
- Canonical vehicle-ID order fixes lane assignment. Each lane retains the production simulator’s slight throttle variation; reversing the query does not change this published comparison.
