TheAston Martin Valkyrie AMR-LMH^[3] is asports prototype developed byAston Martin Racing andMultimatic to compete in theFIA World Endurance Championship in the Hypercar category and theIMSA SportsCar Championship in the GTP category respectively.^[4][5] The car is a heavily modified racing version of theAston Martin Valkyrie AMR Pro fitted toLe Mans Hypercar regulations, making it the only car in its class to be derived from a preexisting production car.^[6]

The Valkyrie AMR-LMH made its debut at the2025 Qatar 1812 km.^[7] The car was originally slated to make its first appearance at the2025 24 Hours of Daytona, however, Aston Martin opted to skip the event in favour of completing more internal testing.^[8] It is the first sports prototype to race with aV12 engine in top class endurance racing in 14 years since thePeugeot 908 HDi FAP and theLola-Aston Martin B09/60 each raced in 2011.

Aston Martin was one of the first manufacturers to commit to theLe Mans Hypercar class in 2019, with plans to start competition with at least two factory cars in the2021 FIA World Endurance Championship. The car was planned to compete without a hybrid system, despite the road car containing one.^[9] Alongside the factory entries, which were to be fielded byMultimatic Motorsports,R-Motorsport were set to run two customer cars.^[10][11]

In February 2020, Aston Martin announced that they would be cancelling the project, citing theAutomobile Club de l'Ouest's decision to allowLMDh sports cars to participate in the Hypercar class.^[11] The LMDh regulations were a more cost-effective solution for manufacturers, which meant customer racing programs were less expensive to invest in for brands and running costs were viable for customer teams. The convergence of the two rulesets significantly impacted Aston Martin's financial model for the Valkyrie race car, as they had anticipated that sales of the Valkyrie to customer teams would constitute a substantial portion of the program's funding.^[12] According toAston Martin executive David King, the development of the project had nearly progressed towards the construction of a fully operational model at the time, with testing set for spring that same year.^[11]

Around this time, Aston Martin had also joinedFormula One for the first time in 61 years, which was followed by an internal restructuring of the British marque's racing division with a primary focus on the company's Formula One andLM GTE programmes.^[11] Despite Aston Martin's decision to pause the project, they remained open to future participation in the Hypercar class.^[13]

The project was revived in October 2023.^[14] Aston Martin planned to enter at least one car in both theFIA World Endurance Championship and theIMSA SportsCar Championship in 2025, run by factory teamThe Heart of Racing.^[4][5] This made them the firstLe Mans Hypercar manufacturer to enter the IMSA series, which up to that point only hadLMDh cars participate.^[15]

The original plan to compete without a hybrid system was carried over to the new car. It uses the same 6.5-litreCosworthRAV12 used by all versions of theValkyrie sports car, but is extensively modified to run leaner in order to meet the Le Mans Hypercar class performance window and to stay reliable throughout all stages of an endurance race.^[3][16] The gearbox is a 7-speedsequential manual developed byXtrac.^[17] Despite not using a hybrid, the car is able to launch from a standstill without requiring engine power, using a combinedstarter andalternator motor system that Aston Martin calls a 'starternator'.^[18]

The car, officially named the Valkyrie AMR-LMH,^[3] was rolled out in the summer of 2024, ahead of an extensive testing program by Aston Martin and The Heart of Racing atSilverstone Circuit andDonington Park with driversDarren Turner,Harry Tincknell, andMario Farnbacher.^[19][20] The team also participated in sanctioned tests with the car later that year, testing atBahrain International Circuit andDaytona respectively.^[21] In November 2024, Aston Martin announced that the car would make its global racing debut at the2025 Qatar 1812 km, opting to skip the2025 24 Hours of Daytona to perform further testing and development.^[8] They also announced that both cars that would be racing in theFIA World Endurance Championship would be using numbers #007 and #009, both taken from their Le Mans-winningAston Martin DBR9.^[22]

In celebration of their return to top class endurance racing at the24 Hours of Le Mans, Aston Martin introduced an unrestricted track-only version of the Valkyrie AMR-LMH in June 2025 called the Valkyrie LM.^[23] The car is nearly identical to its racing counterpart, with only certain racing equipment removed such as ballast and the mandated electronics required for competition in both theFIA World Endurance Championship and theIMSA SportsCar Championship. The Cosworth V12 powertrain was carried over from the race car, reconfigured in order to use standard fuels.^[24] Production is limited to 10 examples.^[25] Through Aston Martin's 'Unleashed' program, owners of the Valkyrie LM are able to drive the car on different racing circuits worldwide with comprehensive support from Aston Martin engineers.^[26]

The driver lineups for all three cars were confirmed in February 2025, primarily consisting of experiencedsports car racing drivers fromAston Martin Racing,The Heart of Racing, andMultimatic Motorsports. Two cars were entered for theFIA World Endurance Championship; the #007, driven byHarry Tincknell andTom Gamble, and the #009, andAlex Riberas andMarco Sørensen.^[22][27]Ross Gunn andRoman De Angelis completed the #23 crew for theIMSA SportsCar Championship.^[22]

The Valkyrie AMR-LMH endured a difficult debut at the2025 Qatar 1812 km, with the #007 retiring with a transmission issue and the #009 completing the race 23 laps down, though the team remained encouraged by the car's potential.^[28] Positive progress continued following Qatar,^[29] recording top 10 finishes in every round of the first half of the IMSA season,^[30] running in points-scoring positions at the2025 6 Hours of Spa-Francorchamps,^[31] and completing the2025 24 Hours of Le Mans without mechanical issues.^[32] Aston Martin showed further competitiveness in subsequent races, including a 6th-place finish at the2025 SportsCar Grand Prix,^[33] fighting in the top 5 at the2025 Lone Star Le Mans before retiring due to overheating issues,^[34] and qualifying in 3rd before finishing 5th with the #009 in the2025 6 Hours of Fuji.^[35][36] At the2025 Petit Le Mans, the Valkyrie AMR-LMH scored its first podium finish in either series, finishing 2nd overall just five seconds behind the race-winningCadillac.^[37]
