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. ## Cite or rerun - [Canonical DragGap result](https://draggap.com/race-results/v1-6be2c1211ea001df/1970-opel-gt-b7288aa18fcc--vs--1970-porsche-914-ae856b85c3a8/) - [JSON](https://draggap.com/race-results/v1-6be2c1211ea001df/1970-opel-gt-b7288aa18fcc--vs--1970-porsche-914-ae856b85c3a8/result.json) - [Rerun these exact stock configurations](https://draggap.com/race-results/v1-6be2c1211ea001df/1970-opel-gt-b7288aa18fcc--vs--1970-porsche-914-ae856b85c3a8/rerun) - [Methodology](https://draggap.com/methodology/)
