Diecast Endurance has kept a Spark Oreca Gibson and a MiniGT Cadillac V running on its homemade rolling-road rig for more than a month. The original report said the run had passed 784 hours, with the Oreca showing a wobbly wheel while the Cadillac appeared to be running with less visible trouble. The final distance and how the test will end are not confirmed.
A Spark Oreca Gibson and a MiniGT Cadillac V have run on a homemade rolling-road rig for more than a month, with the livestream tally passing 784 hours when The Drive reported on the test. The ongoing endurance run has surpassed the earlier mark set by smaller model cars, though the cars’ final running time and distance remain unknown.
The test is being streamed by Diecast Endurance, a YouTube channel hosted by a creator who goes by Mr. Endurance. The homemade setup places scale cars on a moving, belt-sander-like surface, with components intended to hold them in position as their wheels turn. The two current entrants are miniature Le Mans prototypes: an Oreca Gibson made by Spark and a Cadillac V made by MiniGT.
The Drive reported that the run began on Sept. 20 and had continued beyond a month. Its report described the Oreca as showing signs of strain, including a wobbly wheel, while the Cadillac appeared to be running with little visible trouble. The channel’s streams for the test had accumulated across 73 separate broadcasts; individual streams generally lasted about 12 hours, according to The Drive.
The report estimated that, using a scale-up calculation, the cars had covered the equivalent of 92,600 miles. It also said their small wheels had turned enough to represent more than 1,400 miles at full size. Those are estimates based on the test’s distance and scale, not measured road travel, and the figures would change as long as the cars continued running.
A New Benchmark for Model Endurance
The run offers a public, continuously streamed stress test of two commercially made diecast models. Its appeal is partly the direct comparison: the Oreca and Cadillac are on the same rig, so viewers can watch how each holds up under the same ongoing conditions. The visible wheel wobble on the Oreca gives the stream a clear sign of wear, while the Cadillac’s apparently smoother run makes the outcome uncertain.
The figures also put this run well beyond the previous marks described by The Drive. The report said an earlier record belonged to a miniature Ford GT, and that a Mazda 787B model had previously run for almost two weeks. The newer test had already passed those durations. It is not a formal laboratory evaluation, however: the source does not provide controlled testing data, a standardized protocol, or independent verification of the distance estimates. The demonstration shows how these particular models performed on this rig, not how every model from either maker would perform in other conditions.

How the Rolling-Road Test Works
Diecast Endurance began publishing its model-car endurance runs in June, according to The Drive. The rig simulates motion by carrying a model over a moving surface, rather than sending it along a conventional track. The arrangement keeps the cars in view as their wheels spin and allows the channel to leave the test running for extended periods.
The channel’s production setup had grown to five camera views by the time of the report, including overhead, side and front angles, plus a movable camera that was focused on the Oreca’s wobbly wheel. Rather than one uninterrupted month-long broadcast, the test was shown through a sequence of live streams. The Drive counted 73 streams for this run at the time it checked the channel’s live page.
The previous endurance comparisons provide a measure of the run’s length, but the source does not give detailed specifications for the rig, such as its speed, maintenance schedule or how distance is calculated. Those limits matter when comparing a model’s time on the device with mileage on a full-size car.

The Finish Line Is Still Unknown
The source report does not establish when the test will stop or which model will fail first. It also leaves open whether the channel will end the whole run when one car can no longer continue or remove that model and let the other keep running. The status described is a snapshot: the Oreca’s wheel was wobbling, while the Cadillac appeared less affected, but neither the cause nor the eventual outcome was confirmed.
The reported 92,600-mile equivalent and more than 1,400 miles of wheel rotation are estimates that depend on scaling and the point at which the run was recorded. They should not be treated as a final result. The report does not specify the rig’s exact operating speed, whether the cars received maintenance, or whether the channel independently measured and validated the total distance.
The Models Keep Running for Now
At the time covered by The Drive’s report, the endurance test was still underway, and the channel’s successive live streams were continuing to document it. The next clear milestone is whether the Oreca’s wobbling wheel gives out, whether the Cadillac develops visible problems, or whether the organizers stop the run for another reason.
Diecast Endurance had not, in the source material, announced a finish time or a final distance. The eventual result will depend on how the cars and rig hold up and on whether the channel ends the comparison when the first model stops. Until that is clear, the hour count and distance estimates remain provisional.
Key Questions
Which toy cars are being tested?
The test pits a Spark-made Oreca Gibson against a MiniGT-made Cadillac V, both miniature Le Mans prototype models.
How long had the models been running?
The Drive reported that the run began on Sept. 20 and had continued for more than a month, passing 784 hours when the article was published. The exact current runtime is not established by the source material.
How are the cars being tested?
They sit on a homemade, moving rolling-road-style rig that keeps them in place while their wheels turn. Diecast Endurance documents the run through a sequence of livestreams.
Which model is showing more wear?
The report described the Oreca’s wheel as wobbling. It said the Cadillac appeared to be running with little visible trouble at that time, but the final condition of either model is not known.
When will the test end?
No end time was announced in the source material. It is also unclear whether the organizers will stop the entire run when one car fails or continue with the remaining model.
