Lamborghini has lifted the curtain on the powertrain details of its highly anticipated Huracán successor, currently code-named “Lamborghini 634.” The new model, set to debut later this year, will mark a significant evolution in Lamborghini’s lineup by incorporating a sophisticated plug-in hybrid system.
The heart of the new Lamborghini 634 is a twin-turbocharged 4.0-liter V-8 engine, a clean-sheet design featuring a flat-plane crankshaft. This advanced engine boasts a stratospheric redline of 10,000 rpm, far exceeding the 8,500 rpm redline of the outgoing Huracán’s 5.2-liter V-10. The V-8 engine alone delivers an impressive 739 horsepower between 9,000 and 9,750 rpm, with 538 pound-feet of torque available from 4,000 to 7,000 rpm.
This internal combustion powerhouse is complemented by a trio of electric motors. One motor is positioned between the engine and the eight-speed dual-clutch automatic transmission, which is adapted from the Lamborghini Revuelto PHEV. The other two motors are expected to be mounted on the front axle, providing torque vectoring capabilities and enhancing both performance and handling.
The combined output of the hybrid system has not been fully disclosed, but it is anticipated to surpass 800 horsepower, making the new model a formidable successor to the Huracán. The rear electric motor, integrated with an inverter and axial electric unit, contributes 148 horsepower and 221 pound-feet of torque. This setup promises not only exhilarating acceleration but also improved efficiency and the ability to drive short distances on electric power alone.
Lamborghini’s shift to a hybrid powertrain reflects a broader strategy of electrification across its lineup. The Huracán successor follows the introduction of the Revuelto, Lamborghini’s first series-produced plug-in hybrid super-sports car, and the recently unveiled plug-in hybrid Urus SE.
In terms of design, hints from BMW’s head of design Domagoj Dukec and BMW Group Design chief Adrian van Hooydonk suggest the new model will feature a distinctive rear design with a central ridge and a panel gap outlining the trunk lid. The concept, teased with the phrase “the sky is the limit,” suggests a potential open-top or targa configuration, adding to the excitement surrounding the car’s unveiling.
As Lamborghini continues to refine the hybrid system, the company has emphasized maintaining the iconic exhaust note that defines its supercars. Extensive tuning efforts aim to ensure that the new V-8 hybrid sounds as thrilling as its naturally aspirated predecessors.
The official name for the Huracán successor remains under wraps, though “Temerario” has been speculated. Lamborghini CEO Stephan Winkelmann has confirmed that the final name will be inspired by a fighting bull, consistent with the brand’s tradition.
The full reveal of the Lamborghini 634 is expected later in 2024, with more details anticipated in the coming months. This new model will complete Lamborghini’s transition to an all-electrified lineup, setting a new benchmark for performance and innovation in the supercar segment.
