Toyota won the 6 Hours of Portimão 2023 at Autódromo Internacional do Algarve. The #8 Toyota GR010 Hybrid of Toyota Gazoo Racing covered 222 laps over 6 hours, a race distance of 1,033 km. The winning crew: Sébastien Buemi, Brendon Hartley and Ryo Hirakawa. 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 0 lead changes among 1 different car in the HYPERCAR class. At the closest point, first and second were only 0.7 s apart. For 2 of 3 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 (181.6 km/h), Ferrari (180.6 km/h), Cadillac (180.0 km/h).
Between the fastest and the slowest manufacturer in the HYPERCAR class lie 5.8 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 37 cars did not make the finish — an overall retirement rate of 5%. The heaviest toll fell on HYPERCAR with 9%, 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 1.056. That is the winning car — speed and durability came from the same package.
Figure 4 ranks the cars by that score.
The Closing Phase
In the final hour, 73% of the field held position within ±1 place (n = 37). Most of the order was set, but a few fights ran to the end. The biggest single move came from #4 Vanwall, 15 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 #7 Toyota (Toyota Gazoo Racing): 1:32.135 at 181.8 km/h. Crew: Mike Conway, Kamui Kobayashi and Jose Maria Lopez.
Between HYPERCAR and LMP2 sits a pace gap of 2.1 s per lap. That number decides how much traffic the leaders have to work through.
Class winners — HYPERCAR: #8 Toyota (Toyota Gazoo Racing), LMP2: #23 Oreca (United Autosports), LMGTE Am: #33 Chevrolet (Corvette Racing).
Putting the Race in Context
The winner averaged 171.5 km/h across 1,033 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 2023 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.
