Lamborghini has officially confirmed that its upcoming replacement for the Huracan will feature a groundbreaking hybrid powertrain. This new setup blends a twin-turbo 4.0-liter V-8 with electrification, boasting a jaw-dropping 10,000-rpm redline—an extraordinary achievement for any engine, especially a hybridized turbo.
Breaking the News Early
We initially broke this story back in 2022, predicting Lamborghini’s move towards a hybrid V-8 powerplant. Now, with Lamborghini’s public confirmation, we can delve into the specifics of this highly anticipated engine.
The New Engine: Code-Named “634”
The engine, referred to as “634,” will power the Huracan replacement. This codename has historical significance, having been used previously for the Revuelto Coupe in 2017 (LB634). Given this legacy, the new Huracan has big shoes to fill, but Lamborghini’s innovative hybrid V-8 is poised to exceed expectations.
Powertrain Details
Twin-Turbo V-8 with a “Hot Vee” Design
The V-8 engine features twin turbochargers positioned in the valley of the V, known as a “hot vee” configuration. This design is not entirely new, as it’s been utilized by luxury car manufacturers like BMW and in performance engines like Ford’s 6.7-liter Power Stroke. The “hot vee” setup enhances performance by reducing turbo lag and improving throttle response.
Axial Flux Electric Motor
Assisting the V-8 is a 148-hp, 221-lb-ft of torque axial flux motor. This motor provides additional power and efficiency, contributing to the hybrid’s impressive performance metrics. The power is managed by an eight-speed dual-clutch automatic transmission, the same one that debuted on the Revuelto.
High-Revving Performance
What truly sets this engine apart is its 10,000-rpm redline, facilitated by a flat-plane crankshaft—a feature typically found in high-end sports cars. This allows the engine to produce a peak of 789 hp between 9,000 and 9,750 rpm. Despite this high-revving nature, low-end torque remains robust thanks to the axial flux motor, delivering 516 lb-ft of torque from 4,000 to 7,000 rpm.
Additional Traction Motors
Lamborghini has revealed that the Huracan successor will also include two additional traction motors. While specifics on their layout and integration are still under wraps, these motors will further enhance the vehicle’s performance, likely providing improved traction and handling.
Expected Unveiling
Lamborghini plans to unveil the “634” later in 2024, although an exact date has not been announced. The anticipation is building as enthusiasts and industry watchers alike await the debut of this innovative supercar.
Conclusion
Lamborghini’s confirmation of a hybrid V-8 engine with a 10,000-rpm redline for the Huracan successor marks a significant milestone in automotive engineering. By blending high-revving performance with hybrid efficiency, Lamborghini is set to redefine the boundaries of supercar capabilities.
Expect the “634” to deliver exhilarating performance, continuing Lamborghini’s tradition of pushing the envelope in automotive technology. As more details emerge, the excitement surrounding this groundbreaking vehicle will only grow.
