Porsche won the 6 Hours of Bahrain 2015 at Bahrain International Circuit. The #18 Porsche 919 Hybrid of Porsche Team covered 199 laps over 6 hours, a race distance of 1,077 km. The winning crew: Romain Dumas, Neel Jani and Marc Lieb. The margin to second place was 0 laps — a clear, controlled win. The fastest manufacturer also produced the winner.

How the Lead Was Won

Across the race we counted 2 lead changes among 3 different cars in the LMP1 class. At the closest point, first and second were only 0.5 s apart. For 4 of 4 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: Porsche (190.3 km/h), Audi (189.8 km/h), Toyota (186.3 km/h).

Between the fastest and the slowest manufacturer in the LMP1 class lie 12.8 km/h. That is a wide spread. At this track, the concept differences show clearly.

Reliability by Class

All 32 cars were classified at the flag. A race without a single retirement is rare and says a lot about how it was run.

Reliability decided nothing here, so the result came down to pace and strategy alone.

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 #18 Porsche with 1.080. That is the winning car — speed and durability came from the same package.

Efficiency score per car: average lap speed times laps, normalized to the class average.

The Closing Phase

In the final hour, 100% of the field held position within ±1 place (n = 32). The race was settled well before the flag.

Fastest Lap and Class Gaps

The fastest single lap of the race belongs to #18 Porsche (Porsche Team): 1:41.893 at 191.2 km/h. Crew: Romain Dumas, Neel Jani and Marc Lieb.

Between LMP1 and LMP2 sits a pace gap of 7.9 s per lap. That number decides how much traffic the leaders have to work through.

Class winners — LMP1: #18 Porsche (Porsche Team), LMP2: #26 Ligier (G-Drive Racing), LMGTE Pro: #92 Porsche (Porsche Team Manthey), LMGTE Am: #98 Aston Martin (Aston Martin Racing).

Putting the Race in Context

The winner averaged 179.1 km/h across 1,077 km. On a 5.412 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 2015 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.
