Lamborghini's Next HPEV Super Sports Car To Feature Hybrid Twin-Turbo V8 Engine
The second super sports car in Lamborghini's High Performance Electrified Vehicle (HPEV) line-up will feature a new engine capable of reaching 10,000 rpm. Sant’Agata Bolognese, 22 May 2024 – The Lamborghini 634, the code name for the successor to the Huracán, will join the HPEV line-up with a twin-turbo V8 engine. This engine will be combined with a hybrid system incorporating three electric motors and an eight-speed dual-clutch gearbox, optimized for the new model with a maximum output of over 900 CV.
The all-new engine is a clean-sheet design from Sant’Agata Bolognese, aimed at delivering performance and driving emotion that surpass those of the current Huracán range. The twin-turbo V8 combines the high linearity of progression that made the Lamborghini V10 famous with the high power and specific torque of a new-generation turbocharged engine. The twin-turbo V8 features a displacement of 4.0 liters and an exceptional specific power of 200 CV/liter.
The maximum power delivered by the internal combustion engine (ICE) will be 800 CV between 9,000 and 9,750 rpm, reaching a maximum engine speed of 10,000 rpm—a figure normally reserved for racing engines. This makes the new V8 unique among road-going super sports cars. It also boasts a maximum torque delivery of 730 Nm between 4,000 and 7,000 rpm, with an exhilarating progression similar to that of a racing engine, thanks to the perfect integration of the electric unit with the combustion engine.
The rear electric system designed and developed for the new V8 is positioned between the combustion engine and the dual-clutch gearbox. It includes the inverter as well as the axial electric unit. This system is capable of generating high torque and power values, with a maximum of 300 Nm and 110 kW at 3,500 rpm, while still maintaining compact dimensions and low weight.
Another crucial element of the design process was to define the sound, giving the new powerplant a unique and distinctive character. The characteristics of the new V8 intensify in a crescendo that at high revs reaches its peak in terms of volume and frequency content. This, in harmony with the vibrations transmitted to the chassis by the flat-plane crankshaft, creates an all-encompassing sensory experience for drivers.
The launch of the Lamborghini 634 is scheduled for 2024 and marks another milestone in Lamborghini's ‘Direzione Cor Tauri’ program. This initiative is steering Lamborghini towards progressive electrification of its range, beginning in 2023 with the première of the Revuelto and continuing with the unveiling of the Urus SE in April 2024.
