Toyota won the 8 Hours of Portimão 2021 at Autódromo Internacional do Algarve. The #8 Toyota GR010 Hybrid of Toyota Gazoo Racing covered 300 laps over 8 hours, a race distance of 1,396 km. The winning crew: Sébastien Buemi, Kazuki Nakajima and Brendon Hartley. The margin to second place was just 1.800 s — a sprint finish after a full endurance race. The quickest manufacturer over one lap was Alpine — but the win went to Toyota. 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 HYPERCAR class. At the closest point, first and second were only 1.8 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.

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: Alpine (184.2 km/h), Toyota (184.0 km/h), Glickenhaus (181.2 km/h).

Between the fastest and the slowest manufacturer in the HYPERCAR class lie 3.0 km/h. That is a wide spread. At this track, the concept differences show clearly.

Reliability by Class

2 of 32 cars did not make the finish — an overall retirement rate of 6%. The heaviest toll fell on LMGTE Am with 15%, while LMGTE Pro 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 1.051. That is the winning car — speed and durability came from the same package.

The Closing Phase

In the final hour, 91% of the field held position within ±1 place (n = 32). The race was settled well before the flag. The biggest single move came from #20 Oreca, 3 places back.

Fastest Lap and Class Gaps

The fastest single lap of the race belongs to #36 Alpine (Alpine Elf Matmut): 1:30.919 at 184.2 km/h. Crew: André Negrão, Nicolas Lapierre and Matthieu Vaxiviere.

Between HYPERCAR and LMP2 sits a pace gap of 1.3 s per lap. That number decides how much traffic the leaders have to work through.

Class winners — HYPERCAR: #8 Toyota (Toyota Gazoo Racing), LMP2: #38 Oreca (JOTA), LMGTE Pro: #51 Ferrari (Ferrari AF Corse), LMGTE Am: #47 Ferrari (Cetilar Racing).

Putting the Race in Context

The winner averaged 174.4 km/h across 1,396 km. On a 4.653 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 2021 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.
