New Lamborghini Temerario leverages AM for improved cylinder heads

Lamborghini has unveiled its latest marvel, the Temerario, at Monterey Car Week 2024. This super sports car, equipped with a revolutionary 920 CV twin-turbo V8 hybrid powertrain, is not just a leap forward in performance but also a showcase of cutting-edge technology, including the use of 3D printing in the engine’s development.

The Temerario stands as a testament to Lamborghini’s commitment to pushing the boundaries of automotive engineering. As the second model in Lamborghini’s High Performance Electrified Vehicle (HPEV) range, following the Revuelto, the Temerario marks the completion of Lamborghini’s hybridization strategy. This new entrant is not only a powerhouse on the road but also a pioneer in sustainable performance, bringing Lamborghini closer to its ambitious electrification goals but also using AM to improve the ICE.

3D printing to redefine engine cooling

One of the most remarkable aspects of the Temerario is its use of 3D printing technology in the engine’s development, specifically for the casting core of the cylinder heads. This innovation plays a critical role in enhancing the engine’s cooling efficiency—a crucial factor when dealing with the extreme performance demands of a super sports car.

The twin-turbo V8 engine, a completely new design developed in Sant’Agata Bolognese, is engineered to achieve peak performance while maintaining high durability under intense conditions. The 3D-printed casting cores allow for a more refined and uniform cooling system within the cylinder heads. This uniform cooling is vital for maintaining high knock resistance and ensuring optimal combustion conditions, which are essential for the engine’s ability to rev up to an astonishing 10,000 RPM.

The new V8 engine, internally designated as L411, is a masterpiece of engineering. With a specific output of 200 CV per liter, the engine delivers a peak power of 800 CV from 9,000 to 9,750 RPM, with 730 Nm of torque available between 4,000 and 7,000 RPM. This engine is supported by three electric motors—one integrated within the V8 housing and two on the front axle—creating a system output of 920 CV.

The integration of 3D printing technology in the engine’s cooling system not only enhances performance but also showcases Lamborghini’s dedication to utilizing advanced manufacturing techniques. This approach allows for more complex geometries in the engine components, which traditional manufacturing methods could not achieve, leading to improved efficiency and performance.

A new benchmark in super sports cars

The Temerario is more than just a high-performance vehicle; it represents a new paradigm in automotive design and engineering. Its aerodynamic efficiency, combined with the innovative use of materials and manufacturing technologies like 3D printing, sets it apart from its predecessors and competitors alike.

In addition to its technological advancements, the Temerario offers a driving experience that is both exhilarating and refined. With a top speed exceeding 340 km/h (210+ mph) and a 0-100 km/h (0-62 mph) time of just 2.7 seconds, it delivers unmatched performance while also providing enhanced comfort and space for its occupants.

Lamborghini’s Temerario is not just a car; it is a statement of what the future holds for super sports cars—where traditional high-performance engineering meets the latest in digital manufacturing technologies. The use of 3D printing in critical engine components highlights Lamborghini’s forward-thinking approach and its ability to merge innovation with the brand’s storied legacy of performance excellence.

As Lamborghini continues to evolve in this electrified era, the Temerario is a shining example of how the brand is leading the way, setting new standards in both performance and technological sophistication.
