Porsche won the 6 Hours of the Americas 2016 at Circuit of the Americas. The #1 Porsche 919 Hybrid of Porsche Team covered 186 laps over 6 hours, a race distance of 1,025 km. The winning crew: Timo Bernhard, Mark Webber and Brendon Hartley. The margin to second place was 23.6 s, close enough to keep the result open late. The quickest manufacturer over one lap was Audi — but the win went to Porsche. Pace and result do not always match.
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 3.7 s apart. For 6 of 6 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: Audi (185.4 km/h), Porsche (183.2 km/h), Toyota (182.9 km/h).
Between the fastest and the slowest manufacturer in the LMP1 class lie 14.0 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
2 of 31 cars did not make the finish — an overall retirement rate of 6%. The heaviest toll fell on LMP2 with 20%, 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 #8 Audi with 1.051. The winner, #1, is not on top here. Track position and strategy turned into a result that raw efficiency alone does not explain.
Figure 4 ranks the cars by that score.
The Closing Phase
In the final hour, 77% 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 #44 Oreca, 19 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 #8 Audi (Audi Sport Team Joest): 1:47.052 at 185.5 km/h. Crew: Lucas di Grassi, Loïc Duval and Oliver Jarvis.
Between LMP1 and LMP2 sits a pace gap of 8.5 s per lap. That number decides how much traffic the leaders have to work through.
Class winners — LMP1: #1 Porsche (Porsche Team), LMP2: #36 Alpine (Signatech Alpine), LMGTE Pro: #95 Aston Martin (Aston Martin Racing), LMGTE Am: #98 Aston Martin (Aston Martin Racing).
Putting the Race in Context
The winner averaged 170.2 km/h across 1,025 km. On a 5.513 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 2016 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.
