Rebellion won the 6 Hours of Silverstone 2018 at Silverstone Circuit. The #3 Rebellion R13 of Rebellion Racing covered 193 laps over 6 hours, a race distance of 1,137 km. The winning crew: Mathias Beche, Thomas Laurent and Gustavo Menezes. The margin to second place was 1 lap — a clear, controlled win. The quickest manufacturer over one lap was Toyota — but the win went to Rebellion. Pace and result do not always match.

How the Lead Was Won

Across the race we counted 3 lead changes among 2 different cars in the LMP1 class. At the closest point, first and second were only 1.3 s apart. For 5 of 5 measured hours the gap stayed under 30 seconds.

That is a real head-to-head fight, not a comfortable lead.

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: Toyota (212.9 km/h), Rebellion (208.7 km/h), BR Engineering (205.6 km/h).

Between the fastest and the slowest manufacturer in the LMP1 class lie 14.2 km/h. That is a wide spread. At this track, the concept differences show clearly.

Reliability by Class

3 of 34 cars did not make the finish — an overall retirement rate of 9%. The heaviest toll fell on LMP1 with 25%, 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 #7 Toyota with 1.324. The winner, #3, is not on top here. Track position and strategy turned into a result that raw efficiency alone does not explain.

The Closing Phase

In the final hour, 9% of the field held position within ±1 place (n = 34). The closing hour stayed busy, with position changes across the field. The biggest single move came from #7 Toyota, 32 places back.

Fastest Lap and Class Gaps

The fastest single lap of the race belongs to #7 Toyota (Toyota Gazoo Racing): 1:39.602 at 213.3 km/h. Crew: Mike Conway, Kamui Kobayashi and Jose Maria Lopez.

Between LMP1 and LMP2 sits a pace gap of 5.6 s per lap. That number decides how much traffic the leaders have to work through.

Class winners — LMP1: #3 Rebellion (Rebellion Racing), LMP2: #38 Oreca (Jackie Chan DC Racing), LMGTE Pro: #51 Ferrari (Ferrari AF Corse), LMGTE Am: #77 Porsche (Dempsey - Proton Racing).

Putting the Race in Context

The winner averaged 188.4 km/h across 1,137 km. On a 5.891 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 2018-2019 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.
