Porsche will mark the 50th anniversary of its first overall Le Mans 24 Hours victory with special liveries on its pair of 911 RSR-19s at this weekend's race.
The colour schemes on the two GTE Pro class entries celebrate the Weissach marque's 1970 Le Mans win with the Porsche 917 driven by Richard Attwood and Hans Herrmann.
Porsche's #91 car will share the same red and white colours as used by Attwood and Herrmann that year, while the #92 machine will run a variant with black sections in place of red.
The cars will be driven by the same trio of drivers for a third year in a row, with Gianmaria Bruni, Richard Lietz and Frederic Makowiecki aboard the #91 car and Laurens Vanthoor, Kevin Estre and Michael Christensen sharing the #92.
Porsche is running only two cars in the GTE Pro ranks for the first time since 2017 owing to the withdrawal of its two CORE autosport-operated IMSA SportsCar Championship cars due to the global coronavirus pandemic.
They face opposition from two-car entries from regular FIA World Endurance Championship rivals Ferrari and Aston Martin, as well as two privateer Ferraris entered by the Risi Competizione and Scuderia Corsa teams.
It is also the first time the 911 RSR-19, which replaced the previous-generation 911 RSR at the start of the 2019/20 WEC season, will be raced at Le Mans.
"We're competing under completely different circumstances," commented Porsche's head of WEC operations Alexander Stehlig. "The climatic conditions in September are different compared to June.
"There are still some unknowns in terms of weather, temperatures, performance and tyres.
"We'll use the existing data from our WEC and IMSA campaigns as well as the insights gained from testing so that we can hopefully be well sorted for the first free practice session.
"We're competing for the first time with the Porsche 911 RSR-19 here.
"It's not only new for us, but also for the ACO, which handles the BoP. We have complete confidence in the expertise and experience of the specialists.
"Remaining unchanged, however, are the two driver trios in the cockpits. This will be their third year of working together at Le Mans. That's a strength we will build on."
