In an official statement, the brand said it will now "pause" as it "considers whether to continue in any future prototype class". Development of a track-only Valkyrie has been cancelled as a result.
The company cited uncertainty over the recent Automobile Club de l’Ouest (ACO) and International Motor Sport Association (IMSA) decision to combine the hypercar class with the World Endurance Championship's upcoming LMDh prototype category from 2021 and the American WeatherTech Sportscar Championship from 2022.
"We entered the Valkyrie in the WEC and at Le Mans with the understanding that we would be competing with similar machinery and like-minded manufacturers," said Aston Martin CEO Andy Palmer. "The situation has changed and it makes sense for us to pause and reconsider our options."
In response, the FIA Endurance Commission and WEC called the decision "very regrettable but perhaps not unexpected", citing "persistent rumours over the last six months concerning the fragility of the brand’s exposure" and a decision to enter Formula 1 in 2021 as possible reasons for the exit.
The Valkyrie racer was being readied as a competitor to the Toyota GR Super Sport, a new Peugeot hypercar and potentially entrants from Lamborghini and Porsche in the new top-rung endurance category, which replaces the LMP1 class.
Aston’s exit from the hypercar category leaves reigning Le Mans champion Toyota as the sole manufacturer to have confirmed its entry for the 2020-2021 season. Peugeot has announced an intention to race in 2022, while American manufacturer Glickenhaus plans to compete with its new SCG007 racer from 2021 onwards.
It remains to be seen if the FIA racing body, which oversees the World Endurance Championship, will reconsider the launch date for the new class.
