Porsche won the 24 Hours of Le Mans 2017 at Circuit de la Sarthe. The #2 Porsche 919 Hybrid of Porsche LMP Team covered 367 laps over 24 hours, a race distance of 5,001 km. The winning crew: Timo Bernhard, Earl Bamber and Brendon Hartley. The margin to second place was 9 laps — a clear, controlled win. The quickest manufacturer over one lap was Toyota — but the win went to Porsche. Pace and result do not always match.
How the Lead Was Won
Across the race we counted 3 lead changes among 4 different cars in the LMP1 class. At the closest point, first and second were only 1.6 s apart. For 4 of 8 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: Toyota (246.7 km/h), Porsche (246.2 km/h), ByKolles (238.3 km/h).
Between the fastest and the slowest manufacturer in the LMP1 class lie 8.4 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
11 of 60 cars did not make the finish — an overall retirement rate of 18%. The heaviest toll fell on LMP1 with 67%, while LMGTE Am came through best at 6%.
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 #2 Porsche with 1.609. That is the winning car — speed and durability came from the same package.
Figure 4 ranks the cars by that score.
Night Versus Day
Top-class cars averaged 245.0 km/h in daylight and 245.1 km/h at night. The difference is 0.04 km/h — faster after dark.
In other words: no measurable night effect. Darkness costs concentration and makes traffic harder to read, but it does not slow modern prototypes down.
Figure 5 puts both phases next to each other.
The Closing Phase
In the final hour, 87% of the field held position within ±1 place (n = 60). The race was settled well before the flag. The biggest single move came from #31 Oreca, 6 places forward.
Figure 6 shows how settled the finish really was.
Fastest Lap and Class Gaps
The fastest single lap of the race belongs to #8 Toyota (Toyota Gazoo Racing): 3:18.604 at 247.0 km/h. Crew: Sébastien Buemi, Anthony Davidson and Kazuki Nakajima.
Between LMP1 and LMP2 sits a pace gap of 11.5 s per lap. That number decides how much traffic the leaders have to work through.
Class winners — LMP1: #2 Porsche (Porsche LMP Team), LMP2: #38 Oreca (Jackie Chan DC Racing), LMGTE Pro: #97 Aston Martin (Aston Martin Racing), LMGTE Am: #84 Ferrari (JMW Motorsport).
Putting the Race in Context
The winner averaged 208.2 km/h across 5,001 km. On a 13.626 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 2017 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.
