On 17 May 2022, Lamborghini formally announced its entry into both the FIA World Endurance Championship and the IMSA SportsCar Championship starting from the 2024 season. During the 2022 Le Mans press conference, Lamborghini confirmed it would work with Ligier as its chassis supplier, making it the first manufacturer in the LMDh ruleset to select Ligier as a partner.
The SC63 uses a hybrid powertrain consisting of a 90° V8 twin-turbo internal combustion engine paired with standardized hybrid drivetrain components provided by Williams Advanced Engineering, Bosch and Xtrac, for a maximum possible combined output of 671 hp (500 kW).
In November 2022, Iron Lynx was announced as the team responsible for running the factory effort in both series. Lamborghini's Head of Motorsport, Giorgio Sanna, stated the manufacturer aimed to run a single car in the 2024 editions of the WEC and IMSA, with a double entry planned for the 24 Hours of Le Mans. Sanna confirmed Iron Lynx would remain the sole operator of the SC63 during its four-year life cycle ending in 2027.
The car was revealed on 13 July 2023 at the Goodwood Festival of Speed. Its first shakedown took place at Vallelunga Circuit in early August 2023, followed by a first full test at Imola on 10 and 11 August 2023. Driving duties were split between Mirko Bortolotti, Andrea Caldarelli and Daniil Kvyat, covering over 1,500 km. Notable modifications from the demo-spec car at Goodwood included a more squarish cockpit, flaps on the roof before the air intake, and new elements on the rear wing.
For 2024, Lamborghini announced two driver lineups: Andrea Caldarelli, Matteo Cairoli and Romain Grosjean for the IMSA Michelin Endurance Cup, and Mirko Bortolotti, Daniil Kvyat and Edoardo Mortara for the FIA WEC.
The SC63 made its global debut at the 2024 Qatar 1812 km alongside fellow series newcomers BMW, Alpine and Isotta Fraschini. Despite hopes of being competitive, the car qualified 18th, ahead of only the last-placed Isotta Fraschini. It finished 13th overall, demonstrating strong reliability. Two weeks later at its IMSA debut at the 12 Hours of Sebring, the car finished 7th overall. Grosjean performed a strong defensive stint against the race-leading Porsche to avoid the SC63 falling a lap down for an extended period.
Iron Lynx entered two SC63s at the 24 Hours of Le Mans. The No. 63 full-season WEC car finished 10th overall, marking the team's only WEC points finish of the season. The second car, No. 19, driven by the IMSA lineup of Cairoli, Caldarelli and Grosjean, also finished the race.
At the 2024 IMSA Battle on the Bricks, the SC63 exploited wet weather to lead for nine laps. After a drive-through penalty the car used an alternate strategy to return to the front, before retirement following a collision with a Proton Competition Ford Mustang GT3 that damaged the rear suspension.
At season's end, Lamborghini confirmed it would not return to the WEC in 2025, as a mandate requiring two-car Hypercar entries was not viable. Iron Lynx subsequently switched to Mercedes-AMG following a communication breakdown with Lamborghini. Riley Technologies was confirmed to assist with factory operations for the SC63 in IMSA.
In 2025 Lamborghini competed only in the Michelin Endurance Cup rounds of the IMSA SportsCar Championship. The campaign began with retirements at the 24 Hours of Daytona and the 12 Hours of Sebring due to technical issues. The car returned for the Sahlen's Six Hours of the Glen, finishing 7th overall after Romain Grosjean led for 23 laps following a climb through mixed conditions.
On 4 August 2025, Lamborghini announced a pause of the LMDh programme for 2026 and withdrawal from IMSA at the end of the 2025 season, citing a "strategic realignment of its motorsport activities" and a choice to focus on the upcoming Lamborghini Temerario GT3. Lamborghini stated it remained open to resuming the project in 2027 with a suitable factory partner.
Ahead of the 2025 IMSA Battle on the Bricks, Lamborghini introduced an "Evo joker" update featuring an all-new rear suspension package. The car climbed to 5th before a collision in turn 7 with the lapped No. 7 Porsche and a late full-course yellow neutralized its fuel strategy. The SC63 ended its campaign at the 2025 Petit Le Mans, making a late charge against Cadillac and Aston Martin to finish 4th overall — its best performance to date.
