Aston Martin returns to action in the Mobil 1 12 Hours of Sebring on Saturday, 21 March, as the British ultra-luxury, high-performance brand celebrates a year of IMSA WeatherTech SportsCar Championship competition with the stunning Valkyrie hypercar, ahead of Round 2 of the 2026 season.
The Aston Martin THOR Team-run Valkyrie’s participation in the 74th running of one of North America’s most prestigious endurance races, which takes place in Florida, marks precisely one year and six days since the competition variant of Valkyrie made its series debut at the same venue in 2025.
The Aston Martin Valkyrie – the pure racing expression of the world’s ultimate road-going hypercar – is in its second season of competition after an encouraging debut year. The racecar is developed from its production sibling by Aston Martin and The Heart of Racing [THOR] and blends a race-optimised carbon fibre chassis with a modified 6.5-litre V12 powerplant that revs to 11,000rpm and produces over 1000bhp in standard form, but adheres to a strict 500kw (680bhp) power limit as per regulations.
The solitary V12-powered car entered at Sebring, Valkyrie is also the only entry derived from a road-going hypercar competing in either North America’s premier sports car series or the FIA World Endurance Championship [WEC]. It will embark on its 10th IMSA race when it takes the green flag at 1010 EST on Saturday.
Full-season works IMSA drivers Roman De Angelis (CAN) and Ross Gunn (GBR), will once again be joined in the driver line-up by works WEC Valkyrie racer Alex Riberas (ESP). The trio, who were also partnered with works driver Marco Sørensen (DEN) for the Rolex 24 at Daytona in January, finished 10th in the GTP class of the opening race of 2026.
Valkyrie’s maiden IMSA campaign culminated in a brilliant second place overall in the finale, the 2025 Motul Petit Le Mans at Road Atlanta. All told, Valkyrie passed the chequered flag inside the top 10 seven times from eight starts, having finished an admirable ninth on its Sebring debut this time last year.
