Rebellion won the 4 Hours of Shanghai 2019 at Shanghai International Circuit. The #1 Rebellion R13 of Rebellion Racing covered 125 laps over 4 hours, a race distance of 681 km. The winning crew: Bruno Senna, Gustavo Menezes and Norman Nato. The margin to second place was 0 laps — a clear, controlled win. The quickest manufacturer over one lap was Ginetta — but the win went to Rebellion. Pace and result do not always match.
How the Lead Was Won
Across the race we counted 1 lead change among 2 different cars in the LMP1 class. At the closest point, first and second were only 0.9 s apart. For 1 of 3 measured hours the gap stayed under 30 seconds.
The leader was never fully out of reach, but the pressure came in waves rather than all race long.
Figure 1 shows how that gap moved over the distance.
Manufacturer Pace
We rank pace by the average of each manufacturer’s fastest lap. That measures real speed over the distance instead of one lucky lap. The order at the top: Ginetta (180.3 km/h), Rebellion (178.9 km/h), Toyota (178.0 km/h).
Between the fastest and the slowest manufacturer in the LMP1 class lie 2.3 km/h. That is a wide spread. At this track, the concept differences show clearly.
Figure 2 sets the pace order side by side.
Reliability by Class
1 of 31 cars did not make the finish — an overall retirement rate of 3%. The heaviest toll fell on LMP2 with 12%, while LMGTE Am came through best at 0%.
Over this distance, reliability is a result in itself. A car that stops scores nothing, no matter how fast it was.
Figure 3 compares the classes directly.
Efficiency Over the Distance
Our efficiency score multiplies average lap speed by laps completed and compares that to the class average. It rewards cars that were fast and stayed out of trouble. A value of 1.000 is exactly class average.
The top score goes to #1 Rebellion with 1.005. That is the winning car — speed and durability came from the same package.
Figure 4 ranks the cars by that score.
The Closing Phase
In the final hour, 84% of the field held position within ±1 place (n = 31). Most of the order was set, but a few fights ran to the end. The biggest single move came from #77 Porsche, 4 places back.
Figure 5 shows how settled the finish really was.
Fastest Lap and Class Gaps
The fastest single lap of the race belongs to #6 Ginetta (Team LNT): 1:48.428 at 181.0 km/h. Crew: Charlie Robertson, Michael Simpson and Guy Smith.
Between LMP1 and LMP2 sits a pace gap of 3.7 s per lap. That number decides how much traffic the leaders have to work through.
Class winners — LMP1: #1 Rebellion (Rebellion Racing), LMP2: #38 Oreca (JOTA), LMGTE Pro: #51 Ferrari (Ferrari AF Corse), LMGTE Am: #90 Aston Martin (TF Sport).
Putting the Race in Context
The winner averaged 169.7 km/h across 681 km. On a 5.451 km lap, that is the pace the whole strategy had to sustain.
We calculate the same metrics for every race in the archive: pace order, reliability by class, lead changes, winning margin, closing stability and efficiency. That makes this race directly comparable with every other round of the 2019-2020 season — and with the seasons before it.
All figures are derived from the full classification of every race hour and are recalculated with each build.
