Lamborghini Squadra Corse has launched its first hybrid endurance racing prototype, the SC63, at the Goodwood Festival of Speed. The SC63, which will begin testing within weeks, is set to compete in the Hypercar class of the 2024 FIA World Endurance Championship, including the 24 Hours of Le Mans, and in the GTP class of the IMSA WeatherTech Sports Car Championship Endurance Cup, comprising classic races such as the 24 Hours of Daytona and 12 Hours of Sebring. Lamborghini has partnered with Italian team Iron Lynx to run the car in international competition and has signed world-class drivers from the world of Formula 1 and endurance racing.

“The SC63 is the most advanced racing car ever produced by Lamborghini and it follows our roadmap ‘Direzione Cor Tauri’ laid out by the brand for the electrification of our product range,” says Stephan Winkelmann, Lamborghini Chairman and CEO. “The opportunity to compete in some of the biggest endurance races in the world with a hybrid prototype fits with our vision for the future of high-performance mobility, as demonstrated for road legal cars with the launch of the Revuelto. The SC63 LMDh is the step into the highest echelons and into the future of motorsports for our Squadra Corse.”

The SC63 features an all-new 3.8-liter twin turbo V8 engine that has been developed by Lamborghini engineers specifically for the racing program. The engine is a ‘cold V’ configuration, meaning that the turbos are mounted outside the vee angle of the engine which makes them easier to cool and to service. Furthermore, the ‘cold V’ solution lowers the mass and optimizes the car’s center of gravity. This solution, combined with a specifically developed aero balance and attitude, has been identified as the most effective to achieve the best tire grip, and perfect balance, drivability and consistent speed both over a single lap but also across long-distance races.

Power from the engine and the hybrid system, which is standard across the LMDh-category cars, is limited by regulation to 500kW (680 CV). The Power Unit is managed by a Bosch electronic control unit. The LMDh rule set specifies a standard gearbox, battery and motor generator unit (MGU), which helps to contain the development costs for the prototype.

Lamborghini has selected renowned experts Ligier as its partner to develop and build the monocoque. As the first manufacturer to select Ligier on an LMDh project, there was freedom for Lamborghini to specify its requirements, including the development of the push rod front suspension design, overall weight distribution and ease of service for critical parts of the car. The bellhousing, which fills the gap between the rear of the engine and the front of the gearbox, positively affects torsional stiffness, and has been designed to house the electric engine.

Another key aspect of development is the braking system, which must deliver the highest level of performance and reliability in all conditions. The bodywork has been designed by Lamborghini’s Centro Stile design department, in conjunction with the race design team. It features very clear brand styling cues throughout the car, including the iconic y-shaped lights at the front and rear.

The cars will be dressed in a familiar livery, in keeping with the branding seen on the Huracán GT3 challenger. The SC63s will run in Verde Mantis green, with a black Nero Noctis strip over the cabin, front hood, carbon diffuser, rear fin and wing. The cars will also feature green, white and red Italian Tricolore colours, and will carry the branding of longtime partner of Lamborghini, Swiss watch manufacturer Roger Dubuis.
