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 the eight-speed dual-clutch gearbox that recently debuted on the Lamborghini Revuelto, optimized for the new model with a max output of over 900 CV.
The all-new engine is a clean-sheet design from Sant’Agata Bolognese, intending to deliver performance and driving emotion that surpass those of the current Huracán range, if the recent trademark registration from Lamborghini is an indication, the new PHEV Bull could be called Temerio and comes with a twin-turbo V8 combining 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 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 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, 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 and includes the inverter as well as the axial electric unit. It is capable of generating high torque and power values, with a maximum of 300 Nm and 110 kW at 3,500 rpm, while still keeping compact dimensions and low weight, this would mean the power output from the rear electric system delivers about 147 hp, so overall power output of the Huracan successor could be 950 hp, albeit I doubt it would surpass the 1,001 hp of the Revuelto, that wouldn’t make sense marketing wise.
Another crucial element of the design process was to define the sound, to give the new powerplant a unique and distinctive character, and deliver the driver an unparalleled driving experience. The characteristics of the new V8 intensify in a crescendo that at high revs reaches its peak in terms of volume and frequency content and this, in harmony with the vibrations transmitted to the chassis by the flat-plane crankshaft, creates an all-encompassing sensory experience, we are talking about an engine that goes up to 10,000 rpm, that’s Formula One territory, so I’m sure this Raging Bull will scream at high speed.
The launch of the Lamborghini 634 is scheduled for 2024, rumor has it the new Bull will be introduced during Monterey Car Week, which is held in August in California, the United States of America, setting another landmark in the ‘Direzione Cor Tauri’ program that is leading Lamborghini towards the progressive electrification of the range, beginning in 2023 with the première of the Revuelto and continuing with the unveiling of the Urus SE in April 2024, and let’s not forget there should be an all-electric Gran Turismo model on the horizon too by 2025.
