Toyota won the 24 Hours of Le Mans 2019 at Circuit de la Sarthe. The #8 Toyota TS050 Hybrid of Toyota Gazoo Racing covered 385 laps over 24 hours, a race distance of 5,246 km. The winning crew: Sébastien Buemi, Kazuki Nakajima and Fernando Alonso. The margin to second place was 17.0 s, close enough to keep the result open late. The fastest manufacturer also produced the winner.

How the Lead Was Won

Across the race we counted 5 lead changes among 2 different cars in the LMP1 class. At the closest point, first and second were only 1.3 s apart. For 8 of 12 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 (247.9 km/h), Rebellion (245.7 km/h), BR Engineering (244.2 km/h).

Between the fastest and the slowest manufacturer in the LMP1 class lie 7.8 km/h. That is a wide spread. At this track, the concept differences show clearly.

Reliability by Class

12 of 61 cars did not make the finish — an overall retirement rate of 20%. The heaviest toll fell on LMP1 with 38%, while LMGTE Am came through best at 12%.

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 1.356. The winner, #8, is not on top here. Track position and strategy turned into a result that raw efficiency alone does not explain.

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

Night Versus Day

Top-class cars averaged 244.9 km/h in daylight and 245.0 km/h at night. The difference is 0.09 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.

The Closing Phase

In the final hour, 39% of the field held position within ±1 place (n = 61). The closing hour stayed busy, with position changes across the field. The biggest single move came from #68 Ford, 37 places back.

Fastest Lap and Class Gaps

The fastest single lap of the race belongs to #7 Toyota (Toyota Gazoo Racing): 3:17.297 at 248.6 km/h. Crew: Mike Conway, Kamui Kobayashi and Jose Maria Lopez.

Between LMP1 and LMP2 sits a pace gap of 9.6 s per lap. That number decides how much traffic the leaders have to work through.

Class winners — LMP1: #8 Toyota (Toyota Gazoo Racing), LMP2: #36 Alpine (Signatech Alpine Matmut), LMGTE Pro: #51 Ferrari (Ferrari AF Corse), LMGTE Am: #56 Porsche (Team Project 1).

Putting the Race in Context

The winner averaged 218.6 km/h across 5,246 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 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.
