Toyota won the 6 Hours of Shanghai 2017 at Shanghai International Circuit. The #8 Toyota TS050 Hybrid of Toyota Gazoo Racing covered 195 laps over 6 hours, a race distance of 1,063 km. The winning crew: Sébastien Buemi, Anthony Davidson and Kazuki Nakajima. The margin to second place was 1 lap — 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 2 different cars in the LMP1 class. At the closest point, first and second were only 0.4 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.

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 (185.2 km/h), Porsche (184.7 km/h).

Between the fastest and the slowest manufacturer in the LMP1 class lie 0.5 km/h. That is a tight field — the balance of performance is doing its job.

Reliability by Class

2 of 26 cars did not make the finish — an overall retirement rate of 8%. The heaviest toll fell on LMGTE Am with 20%, while LMP2 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 Toyota with 1.014. 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, 88% of the field held position within ±1 place (n = 26). The race was settled well before the flag. The biggest single move came from #38 Oreca, 3 places back.

Fastest Lap and Class Gaps

The fastest single lap of the race belongs to #8 Toyota (Toyota Gazoo Racing): 1:45.892 at 185.3 km/h. Crew: Sébastien Buemi, Anthony Davidson and Kazuki Nakajima.

Between LMP1 and LMP2 sits a pace gap of 6.2 s per lap. That number decides how much traffic the leaders have to work through.

Class winners — LMP1: #8 Toyota (Toyota Gazoo Racing), LMP2: #31 Oreca (Vaillante Rebellion), LMGTE Pro: #67 Ford (Ford Chip Ganassi Team UK), LMGTE Am: #98 Aston Martin (Aston Martin Racing).

Putting the Race in Context

The winner averaged 176.8 km/h across 1,063 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 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.
