The Lamborghini 634, the code name for the successor to the Huracán that will join the High Performance Electrified Vehicle (HPEV) line-up, will be equipped with a twin-turbo V8 engine, combined with a hybrid system incorporating three electric motors and an 8-speed dual clutch gearbox for a maximum output of over 900 horsepower.
The all-new engine is a clean-sheet design from Sant’Agata Bolognese. The twin-turbo V8 combines the linearity of the normally-aspirated Lamborghini V10 with the high power and specific torque of a new-generation turbocharged engine.
The twin-turbo V8 features displacement of 4.0 liters and an exceptional specific power of 200 horsepower per liter. The maximum power delivered by the internal combustion engine alone will be 800 horsepower between 9,000 and 9,750 rpm, reaching a maximum engine speed of 10,000 rpm: a figure normally reserved for racing engines and making the new V8 unique in the landscape of road-going super sports cars. It is also unique in terms of the maximum torque delivery of 730 Nm between 4,000 and 7,000 rpm.
The rear electric system designed and developed for the new V8 is positioned between the combustion engine and the dual-clutch gearbox and includes the inverter as well as the axial electric unit. It can generate high torque and power values, with a maximum of 300 Nm and 150 horsepower (110 kW) at 3,500 rpm, while keeping compact dimensions and low weight.
The launch of the Lamborghini 634 is scheduled for 2024 and is another landmark in the ‘Direzione Cor Tauri’ program that is leading Lamborghini towards the progressive electrification of the range.
